APPRAISAL STUDY ON THE SENSITIVITY OF ECO ENVIRONMENT IN KARST REGION

-A Case Study of the Wujiang River Valley Su Weici (Institute of Mountain Resources of Guizhou)  
Karst mountain is widely distributed in the Wujiang River valley of Guizhou Province, where the bearing capacity of karst environment is low, the land surface is rugged and eco environment is fragile. Taking the Wujiang River basin as an example, this paper deals with the principles and methods of evaluation of eco environmental sensitivity and establishes preliminarily the index system of evaluation in karst region by analysing the relationship between human activity and environmental changes. Based on the analysis,the weight of each factor (appraisal index) influencing eco environmental sensitivity is determined with AHP method,and the value of eco environment sensitivity in each county (or city, district, etc.) in the Wujiang River valley is also calculated, which will provide the basis for developing and harnessing the Wujiang River valley.
