ABSTRACT
Bamboo forest carbon sequestration has strong
development potential in coping with global climate
change. The management of Moso bamboo forest can exert
its own strong carbon sequestration ability and promote
farmers' income, which is the fundamental point of bamboo
industry development and can integrate ecological,
economic, and social benefits. In this study, two Moso
bamboo forests with different management modes in
Lin'an and Yuhang of Zhejiang Province were used as
research points. Using the system dynamic thinking
method, a dynamic system model was constructed to
simulate the growth process of Moso bamboo and its
carbon sink supply. Then comparative analysis was made
of its carbon sink supply potential. It is easy for bamboo
forest managers to change management measures
according to their requirements and create a dynamic
balance between ecology and economics when determining
the optimum management mode for the bamboo forest
under the supply potential of carbon sink. According to the
study results, the carbon sink supply under the intensive
model is the most ideal, while the carbon sink supply under
the extensive peach blossom model is the least ideal.

I. INTRODUCTION
With the development of industrialization,
global climate change, mainly characterized by the
greenhouse effect, is severe. It is urgent to reduce the
concentration of carbon dioxide in the atmosphere. In
contrast to the potential economic slowdown associated
with industrial Emissions reduction, forest carbon sinks
absorb carbon dioxide from the atmosphere and fix it in
vegetation or soil, effectively lowering the atmospheric
carbon dioxide concentration, which is viewed as a
beneficial attempt to address climate change.
Phyllostachymosa has become the focus of attempts
among all forest resources due to its fast growth rate,
early timbers, and strong carbon sequestration ability
(Dai Jingsheng, Tan Sanqing, Chen Chunxi, 2009).
Furthermore, in the context of the global forest resources
decreased significantly, the distribution of bamboo forest
area has continued to grow at a rate of 3%. Among them,
the area of bamboo forests in China is nearly 5.381
million hm2, which provides a solid foundation for
studying the carbon sink of bamboo (Xia Enlong , Jiang
Zehui, Li Zhiyong, 2014).
With the development of economy and the
change of environment, the management types of Moso
bamboo forest include timber forest, bamboo shoot
forest and bamboo shoot forest, and Moso bamboo
carbon sequestration forest with the primary objective of
ecological benefit. Therefore, further scientific research
is needed. However, the growth of the bamboo forest is a
complex and comprehensive system, which is affected
by natural growth, human management, and the
economy at the same time. Therefore, we need to
comprehensively consider the mutual influence among
various factors and think about it systematically and
dynamically.
II. OVERVIEW OF THE STUDY
Located in the south of the Yangtze River,
Hangzhou is a subtropical monsoon area with four
distinct seasons and abundant rainfall. Superior natural
climate conditions have become a traditional bamboo
planting, planting a long history, planting a wide area.
According to the inventory report of Hangzhou Forestry
and Water Resources Bureau, in 2016, there was a total
bamboo forest area of 164,100 hm2 in Hangzhou,
including 112,400 hm2 of bamboo forest.
In 2007, initiated by the International Bamboo
and Rand Organization, the world's first bamboo carbon
sequestration forest base was set up in Yanjia Village,
Lin’an, in cooperation with China Green Carbon Fund,
China National Petroleum Corporation and Zhejiang
Agriculture and Forestry University. The base covers
about 800 mu and is located at the southern foot of
Tianmu Mountain with an average altitude of about 300
meters. It is a high mountain and hilly terrain with a
general trend of inclination from northwest to southeast.
There are many stones on the ground and the soil is
poor. Before the planting of bamboo, it was a secondary
forest dominated by Chinese fir. Lin'an Fudebao
Agriculture and Forestry Development Co., Ltd will
conduct initial afforestation and daily management and

maintenance of the base. The management style of
"peach blossom cultivation" (Chen Xin’an, 2010) is
used. Bamboo shoots are generated year but not
excavated; old bamboo is allowed to decay on the
mountain after being chopped down; weeding is done
manually every other year.
In 2013, the research group investigated the
growth status and carbon sink supply of
Phyllostachyspubescara in the base and compared the
growth status and carbon sink supply of
Phyllostachyspubescara in the ordinary operating
households Cibi village of Yuhang. The bamboo forest
in Cibi Village of Yuhang is a traditional timber forest.
The bamboo forest here adopts the management mode of
"big and small years" (ZouGuanhui, 2013), that is, in the
big year, bamboo shoots are kept to raise bamboo, while
in the small year, bamboo shoots are dug and cut down.
It was found that the carbon sink supply of
bamboo was affected by many factors. From the
biological point of view, the natural climate, soil, and
topography all had different effects on the carbon
storage of bamboo. From the economic point of view,
the carbon sink supply of bamboo is also significantly
affected by the price of bamboo, the price of carbon sink
and the management mode. The peach blossom pattern
adopted in the base was lower in bamboo number,
biomass and carbon sequestration supply potential than
that adopted in Yuhang. Because carbon sequestration
forest was still a new bamboo forest in 2013, the
research team conducted a follow-up survey in Yanjia
Village and Cibi Village in November 2016 and April
2018, respectively, to further investigate the difference
in carbon sequestration potential between carbon
sequestration base and common bamboo forest and to
ascertain the impact of management mode.
II. RESEARCH METHODS AND
THEORETICAL FRAMEWORK
2.1System Dynamics and Model Design
Systems thinking, also known as system
dynamics (SD), is a system simulation method that
builds mathematical or logical relationships between
variables based on the interrelationships between system
behavior and internal mechanisms. This way of thinking
about the nature of the overall operation is to integrate
structural methods, functional methods, and historical
methods into A whole and seek ways to improve the
system's behavior from the whole (Isagiy, Torii A,
1998).
Model including flow rate, the essential
elements and auxiliary variables, is not based on abstract
assume but grasps "every system and structure, the
system structure of decision system" the system of
scientific thought, on the premise of reality, on the basis
of social system dynamic behavior, careful
considerations the interaction relationship between all
the factors, build a simulation model of the system
simulations to predict the future behavior, Form a
negative feedback chain of information to provide
suggestions for development decisions.
Bamboo forest growth is a system in which
natural growth process, human management process and
economic process interact. The price of bamboo in
bamboo market will affect the management enthusiasm
and management level of bamboo forest managers. For
example, water and fertilizer will affect bamboo shoot
emergence rate, average DBH, biomass, and carbon
sequestration. The cutting rate will affect bamboo stand
number. Finally, these stand structures will affect
bamboo stand biomass and carbon storage. Bamboo
supply and carbon sink supply regulate bamboo market
and carbon sink market, respectively. A comprehensive
system of interactions is thus formed, as shown in Figure
2.1:
Figure 2.1: Influence mechanism of management mode on carbon sink supply
management model bamboo growth
bamboo price bamboo supply
Price of carbon sequestration Carbon sequestration supply

The software Stella 9.1.3 was used to build the
model. The growth system of bamboo forest was taken
as the core, and under the influence of management
mode, the bamboo market and carbon sink market were
synergistic connected. As shown in Figure 2.2:
Figure 2.2: Bamboo Forest growth system
The growth system of bamboo forest was
established based on the biological characteristics of
Phyllostachyspudostachys, and the flow consisted of
inflow and outflow, namely, the number of one-year
bamboo shoots and the number of eight-year old bamboo
shoots. The stock is the number of trees in each age
group, and the rate is the bamboo shoot cutting rate and
bamboo timber cutting rate. The natural growth cycle of
Phyllostachyspubescens is eight years, and the number
of bamboo shoots at one year is based on the number of
bamboo shoots at two, three and four years. The natural
survival rate is set to 80%, and it is affected by the
density of bamboo stands. More than four years of
bamboo can begin cutting, cutting is equal to the age of
bamboo amount multiplied by cutting rate.
Phyllostachyspuescens dies naturally in the eighth year
and its growth chain terminates. Considering the actual
situation, the natural loss rate of bamboo was set as 2%.
The total biomass of bamboo forest was calculated based
on the bamboo age and DBH according to the research
of scholars such as Zhou Guomao. The carbon sink is
obtained by multiplying the biomass by the carbon sink
coefficient.
The bamboo market takes the price of bamboo
as the center, influences the growth of bamboo forest by
controlling the cutting and cost input of bamboo, and
then establishes the connection with the growth system
of bamboo forest. Since Ci Bi Village is a timber forest
and Yanjia Village leaves bamboo shoots every year, the
income of bamboo forest operation refers to the income
of bamboo, which is equal to the amount of bamboo cut
multiplied by the price of bamboo. Profit is sales minus
costs, which mainly include management costs and
cutting costs. Management cost is the sum of fertilizer,
herbicide and daily maintenance cost, while cutting cost
is the sum of labor cost and transportation cost.
Therefore, the management of bamboo stands is
affected by the price, and there are different intensive
management inputs, which then affect the stand structure
of bamboo stands. On the one hand, stand structure
affects the growth rate of annual bamboo shoots. High
bamboo stand density will limit the growth space of
bamboo shoots. The other affects the overall biomass of
the bamboo forest and ultimately affects the amount of
carbon sink supply of the bamboo forest. The supply of
carbon sink is also affected by the price of bamboo and
carbon sink .
2.2 Bamboo Biomass and Carbon Sink calculation
Method
There are different calculation methods for the
relationship between stand structure factors and biomass.
At present, the most accurate is the binary biomass
model for a single plant established by Zhou Guomao et
al in 2010, as shown below:

Where, f (D, A) is the calculated biomass of A
single plant (kg), D is the DBH (cm) of A single plant, A
is the age of A single plant, and the total biomass is
obtained according to the sum of the biomass of all
single plants (Fan Yeqing, Zhou Guomao, Shi Yongjun,
2012).
Meanwhile, the study showed that the carbon sink
supply of Phyllostachymosa was determined by the
biomass of Phyllostachymosa, which was obtained by
the biomass multiplied by the carbon content coefficient
0.504 (Zhou Guomao, Jiang Peikun, Xu Qiufang, 2010).
2.3 The Influence Mechanism of Different
Management Modes on the Supply Potential of Carbon
Sinks
Different management modes of bamboo
forests adopt different management measures. Through
fertilization, weeding and cutting, combined with the
differences in management level, the non-spatial
structure of bamboo stands can be directly or indirectly
affected, which is mainly reflected in the bamboo stand
number, average DBH, bamboo height, bamboo age and
other factors (ZhengZerui, 2016). However, stand factors
will affect the biomass of bamboo stand, and then affect
the carbon sink, forming the chain of "management
model-stand structure-biomass -carbon sink".
But at the same time, the supply of carbon sinks
in turn affects management patterns. By regulating
carbon sink price through supply, the management
enthusiasm of bamboo forest managers will be affected,
resulting in different management mode and
management input. In this way, a complex system with
loop and negative feedback chain is formed.
III. DATA COLLECTION METHOD
AND SURVEY RESULTS
3.1 Data Collection Method
In this paper, two moso bamboo forests in Cibi
Village of Yuhang and Yanjia Village of Lin'an were
selected as the research points. Field measurements and
questionnaire interviews were carried out, and the
obtained data were simulated and compared. The two
research sites are also located in Hangzhou City,
Zhejiang Province, with similar geographical locations
and nearly the same natural climate conditions. Under
this premise, the effects of different bamboo forest
management patterns on carbon sink supply potential are
more comparable。
3.1.1 Field Survey
Through field survey to understand the growth
status of bamboo forests, two sample plots with similar
size and range were designated in two bamboo forests.
Under the guidance of local experienced villagers, the
area and slope were measured, the bamboo shoots and
the number of bamboo trees were counted, the bamboo
age of each bamboo was determined and the diameter at
breast height was measured. The diameter of the breast
was measured with a soft ruler at a distance of 1.3
meters from the root, and the value was accurate to
millimeters. After the measurement was completed, the
original data were recorded and simple processing was
done to show the basic growth condition of the bamboo
forest.
3.1.2 Interview with Key Informants
Through the information interview of the
bamboo forest operators, the development background of
each bamboo forest and the input and output under
different management modes were understood in detail.
The background includes the origin of bamboo forest
and the specific management and protection measures of
bamboo forest. The investment mainly includes the cost
of fertilizer, herbicide, pest control, bamboo cutting and
handling, manual management and maintenance,
transportation, capital interest, etc. The income includes
the sales income of bamboo shoots, sales income of
bamboo materials, carbon sequestration transaction
income and government subsidies, etc. In addition, the
operators are asked questions about the knowledge of
carbon sink, so as to understand their cognition of
carbon sink and reflect the prevalence of carbon sink in
China.

* Since bamboo shoots had been cut down during the survey in Cibi Village in 2018, the data was estimated with the
assistance of the householders.
As shown in Table 3.1, the measured areas
selected in Yanjia Village of Lin'an in 2013 and 2016 are
roughly similar, respectively 380m2 and 330m2, and the
total number of bamboo stands counted is 137 and 176,
respectively. In three years, the average DBH on the site
increased from 5.02cm to 8.03cm, but this was due more
to the natural growth of the new bamboo forest. Among
them, in the survey of moso bamboo forest in Yanjia
Village, Lin'an in 2013, because the project base newly
made moso bamboo in 2008, there were only four years
old or less bamboo. After four years of operation and
management, without cutting down bamboo and digging
bamboo shoots, the number of plants has not increased
significantly, which reflects the extensive management .
The measured area of Yuhang Cibi village is
similar, but the total number of standing trees is
obviously reduced. The mean DBH did not change much
and remained about 8.5cm. In addition, the moso
bamboo forest was in the "big year" when the survey
was conducted in 2013, and in the "small year" in 2018.
In the big year, bamboo shoots were kept to raise
bamboo, while bamboo shoots were dug and cut in the
small year. So, in both measurements, the bamboos 'ages
were staggered. In 2013, annual bamboo shoots, three-
year bamboo and five-year bamboo were added, while in
2018, biennial bamboo and quadrennial bamboo were
added. Among them, the number of 1-year-old bamboo
stands in 2018 was 138, which the operator estimated as
the number of bamboo shoots removed.

Source: Key person information interview, the above data are calculated at current prices.
It can be seen from Table 3.2 that the management
modes of the two bamboo forestlands are different. In
terms of fertilizer and pesticide input, Yanjia Village in
Lin'an has always been 0 yuan. This is because carbon
sink afforestation is for environmental protection, and
the project contract requires that no chemical fertilizer,
pesticide, and herbicide be used, and no mechanical
operation should be allowed. The only way to do this is
by weeding the grass by hand, so all this labor will be
transferred to the labor cost. In 2013, YuhangCibi
Village spent 500 yuan/mu on fertilizer and 20 yuan/mu
on pesticide, which is a fine management of bamboo
forest. However, in 2018, chemical fertilizers and
pesticides were stopped due to the low price of bamboo,
which led to a decrease in management enthusiasm.
In terms of labor costs, Yanjia Village in Lin'an
is about 150,000 yuan a year, mainly used for weeding
and chopping old bamboo for many years. The weeds
are left on the mountain and used as fertilizer for
bamboo groves. The labor cost of Cibi Village in
Yuhang was 280 yuan/mu in 2013, but decreased to 93
yuan/mu in 2018, because the latter had a low
willingness to invest in bamboo forest management,
relatively extensive management, and the labor cost was
only used for splitting the mountains.
In terms of transportation cost, both places are 0
yuan, but the reasons are different. At the early stage of
Yanjia Village in Lin'an, there was no demand for
transportation because of the newly built bamboo forest
and no bamboo to cut down. Later, because the price of
bamboo is down, operators are reluctant to cut bamboo
sales. Therefore, no bamboo has been sold in the project
so far, so there is no corresponding transportation cost
expenditure. Although YuhangCibi village is at a higher
altitude, the buyer is "door-to-door acquisition". The
operator only needs to transport the cut bamboo to the
intersection, and the transportation cost is almost zero.
It is worth noting that Yanjia Village in Lin'an
is a carbon sink afforestation with a large initial
investment cost, which is apportioned according to the
20-year operating period and the interest on the capital is
calculated at 5%. In 2013, the capital interest was 17
yuan/mu, and in 2016, it was 10 yuan/mu, indicating that
the investment is decreasing relatively.
According to the interview, the bamboo market
has changed greatly in recent years, especially the
bamboo price has plummeted from 1000 yuan/ton in
2013 to 400 yuan/ton in 2016 and 2018, which has a
great impact on the bamboo sales. On the carbon
exchange market, the carbon sink price has been
hovering at a low level, and the price has not been able
to rise to 100 yuan/ton as expected by experts.

peach blossom：Bamboo forest shoots and grows every year, but the amount of growth in adjacent years is similar.

It can be seen from the field investigation that
in 2013, the bamboo forest in Cibi Village of Yuhang
was carefully managed and maintained, and the bamboo
forest grew very well. The bamboo forest was solid and
robust due to the significant average investment per mu,
and it was a typical intensive management model for the
big and small years. However, in 2018, due to the low
price of bamboo market and the depressed market,
operators were unwilling to invest. The management was
relatively extensive, and the The number of established
trees was relatively reduced. In addition, cutting bamboo
and digging bamboo shoots in the junior year had a
sense of sparsity, which was the extensive management
mode of the big and small years.
In 2013, the bamboo base in Yanjia Village of
Lin'an was not long after the new bamboo forest was
built, so there were few weeds in the bamboo forest and
no lodging of bamboo. Due to the restriction of carbon
sink forest management, not fertilizer, pesticide, not
mechanized operation, its own management measures,
relatively large and small years more extensive, is a
semi-intensive peach blossom management mode. In
2016, weeds were overgrown in the bamboo forest, and
most bamboos were malnourished with more lodging.
And the old bamboo no felling, let its natural decay,
visible on weekdays basically no management. This
situation is far from the fine management degree in
afforestation. Relatively speaking, the management level
is obviously reduced and the management intensity is
low, which is the extensive management mode of peach
blossom.
IV. RESULTS AND ANALYSIS
Using the model to run the derived data, the
curve difference of carbon sink supply of bamboo forest
under different management modes was compared and
analyzed. Due to the difference in the total area of the
two bamboo forests, the carbon sequestration per hectare
was selected as the index to achieve effective
comparison. The simulation time of the system was set
as 20 years, and the trend of carbon sink supply from
2013 to 2033 was observed. At the same time, starting
from 2013, 2016 and 2018, the differences in simulation
results were compared. Finally, the degree of
intensification is taken as the influencing factor to
simulate the curve of carbon sink supply under different
intensification degrees.
4.1 Comparison between Peach Blossom and Chinese
New Year
Figure 4.1: Different carbon sink supply under different models
According to the survey in 2013, the carbon
sink supply potential of semi-intensive peach blossom
plantation was lower than that of intensive big and small
years, but the carbon sink forest in 2013 was newly
created bamboo forest. In order to eliminate the
influence of new and old bamboo forests on the contrast,
the peach blossom plantation after 2016 was compared
with that of big and small years in 2018. From Figure
4.1, we can see that the bamboo forest carbon sink
supply is more ideal under the management mode of the
big and small years. This is due to the more sophisticated
management model itself, the use of chemical fertilizers,
pesticides, reduce pests and diseases, provide sufficient
nutrients. It is beneficial to make better use of natural
conditions and site space by cutting bamboo regularly
and spacing mature bamboo ages reasonably. But the
peach blossom does not cut bamboo, bamboo for
nutrient absorption is competitive, too much bamboo
will not only affect the shoot growth rate, but also lead
to the development of bamboo, small DBH affects the
biomass accumulation, thus affecting the supply of
carbon sequestration. But paradoxically, the application
of chemical fertilizers and pesticides in the early and
early years has a greater negative impact on the
environment, which is environmental pollution to a
certain extent, and runs counter to the original intention
of carbon sink.

4.2 Comparison of Peach Blossoms with Different Intensification Degrees
Figure 4.2
Fig. 4.2 shows that the carbon sink supply of
semi-intensive and extensive peach blossom is not high,
and the carbon sink supply per hectare will fluctuate
between 0.75 to 1.5 tons around 2024. This value is very
different from the 5.26-6.51 tons of carbon sequestration
per hectare proposed by MengHaiyue, Liu Qiang et al in
2014. It shows that under the management mode of
peach blossom, the benefit of woodland is not high. The
reason why the two are similar is that the management of
peach blossom itself is relatively extensive.
However, the carbon sink supply of extensive
peach blossom plantation was higher than that of semi-

intensive peach blossom plantation, which did not
indicate that extensive peach blossom plantation was
more powerful in carbon sink supply. The reason was
that in 2013, the carbon sink forest base was at the initial
stage of afforestation, and there were only four years old
and less bamboo, which affected the carbon sink supply.
4.3 Comparison of Old and Young Years with Different
Intensification Degrees
Figure 4.3
As shown in Fig. 4.3, the carbon sink supply in
intensive years is obviously better than that in extensive
years, and the overall supply in extensive years
decreases greatly. It shows that the difference in
management input greatly influences the carbon sink
supply under the big year and small year model. The
carbon sink supply of intensive years is very large,
because under this management mode, bamboo forest
investment is very large, through pesticide, chemical
fertilizer and reasonable cutting fine management, so
that the forest bamboo growth is good, increase the
carbon sink supply.
The above comparison shows that intensive
operation is more conducive to carbon sink supply under
the same management model. In order to further
determine the impact of intensification degree on the
supply potential of carbon sink, the simulation
comparison is made as follows.
4.4 Comparison and Simulation of Different Intensities
Assume that the intensification degree is 0.2,
0.4, 0.6, 0.8, and 1 respectively, and simulate the carbon
sink supply amount under the peach blossom planting
and the big and small year model, and the results are
shown in the figure below.

4.4.1 Large and Small Year Model
Figure 4.4
As shown in Figure 4.4, the degree of
intensification has a certain influence on the carbon sink
supply of bamboo forest under the Big and Small Year
model. When the degree of intensification is 1, the
maximum carbon sink supply reaches 8t/ha. Even if the
degree of intensification is 0.2, the highest is nearly
6.5t/ha. Taking the degree of intensification as 0.6 and
0.8, the calculated elastic coefficient is 0.1. It indicated
that the more the management input, the more ideal the
carbon sink supply of bamboo forest. However, the
degree of intensification has an influence on the
management model in the first and second years, and the
subsequent influence is not obvious, indicating that the
degree of intensification has an upper limit.

Figure 4.5
As shown in Fig. 4.5, there was also a positive
correlation between the degree of intensification and the
carbon sink supply of the bamboo forest under the
annual pattern of peach blossom. The higher the degree
of intensification, the more the carbon sink supply.
Taking the degree of intensification as 0.6 and 0.8, the
calculated elastic coefficient is 0.23. The increase of
management input will have a positive impact on the
supply of carbon sink. Moreover, the effect of
intensification degree on the pattern of peach blossom
lasted for more than 20 years.
By comparing Figure 4.4 and Figure 4.5, it can
be seen that the degree of intensification has an influence
on both the big and small years model and the peach
blossom planting model, but the influence on the peach
blossom planting model is more significant. The reason
is that peach blossom itself is relatively more extensive,
after the change of management input, the impact degree
is relatively large. The model itself is more finely
managed and the impact of management input is smaller.
V. CONCLUSION
The difference of carbon sink supply potential
among different management modes is mainly due to the
degree of intensification, ie the amount of management
input. The carbon sink supply is expected to reach 35t/ha
in the highly intensive degree, and only 1-2t/ ha in the
extensive mode. Compared with the two, there is a big
gap. Intensive management is more ideal than extensive
management, which is beneficial to increase the number
of bamboo trees per unit area, so as to increase the
carbon sink supply and carbon sink. The management
mode of Daxian is better than that of Peach Blossoms. In
terms of management input, it is more refined than that
of Peach Blossoms. From the biological point of view,
the big and small years more in line with the biological
characteristics of bamboo forest. In conclusion, intensive
management of the DaXiaNian mode is the most ideal
carbon sink supply, extensive management of peach
blossom mode is the least ideal carbon sink supply.
