Abstract
The objectives of this study are: (1) to design the fragile indicators of ecological fragility for plantation, and select the potentially resistant species to stress from different sensitivity sites; (2) to understand the foundations of forest degradation and accommodation in climat change using the simulation of ecological fragility; (3) to establish a dynamic model of ecological energy for analyzing sediment yield in varied climates;(4) to study the corresponding strategies for dealing with disasters caused by climate change in the watershed.
