3. The changes in land use include loss of agricultural
lands, forest lands and increase of barren land and
impermeable surface of the area-caused UHI
phenomena
In Malaysia, among the most significant changes in
land surface conversion was the residential land
use, especially in Klang Valley (Takeuchi et.al, 2010)
Therefore, it is vital to have further understanding
in monitoring and investigating the land use
changes impacts in the urban microclimate
especially to conserve the forest reserve
3
4. The aim of this study is to
investigate the effects of land use
changes on the microclimate of
area surrounding in Botanical
Garden Bukit Cerakah in the city
of Shah Alam
4
5. The research objectives are as follows:
To generate land use/ land cover map
changes detection,
To develop the land surface temperature
(LST) map, and
To investigate the temperature distribution
within the multi land cover context in urban
area

12. 1 Gain the digital number (DN) from the thermal
infrared band (Band 6) from Landsat image.
2. Conversion from DN to brightness temperature
using quadratic regression model (Malaret
et.al., 1985):
T(K)=209.831+0.834*DN-0.001372*DN*DN
Where;
T(K) = temperature in Kelvin degree
DN = the thermal infrared band pixel value
*To convert brightness temperature to degree
Celsius = (degree Kelvin)-273.15

18. 1) Variance of temperature rise in most
developed area.
2) Vegetative area remain cooler radiant
temperature.
3) Disturbing human thermal comfort.

19. Increase the vegetations (parks, trees etc) to
replace loss of natural greenery in new urban
development.
Climatic consideration in future urban
development to perform sustainable
development.
Seriously manage the UHI effects in various of
fields and technology.
