6. Forest Tenure and Transition
林地权属和森林转型

7. 云南森林转型的三种类型

8. Forest transition pathway(森
林转型途径)：
1. economic development
pathway (滇东北的外出
打工型)
2. smallholder intensification
pathway (滇南和滇西南
的经济林木种植的劳力
输入型)
3. forest scarcity pathway (滇
中地区的森林缺乏、经
济增长和劳力输入).
4. Conservation pathway (滇
西北森林保护和旅游开
发和劳力输入).
森林转型和人口流动
