Ecological Risk Assessment of the Giant Panda Habitat in Jiajin Mountains in Sichuan of China

摘要

In the frame of plotting study area - risk sources analysis - risk suffer analysis - risk exposure analysis - risk imperil analysis - risk integrated analysis, taking Baoxing County for example, the ecological risk sources of the Giant Panda Habitat in Jiajin Mountains was estimated. Taking the Giant Panda and habitat as ecological risk receptor, the ecological loss degree and 4 indicators were proposed to estimate ecological index. They were distribution probability, diversity of species index, ecological system dominance index and natural index. Based on GIS technology and the integrated ecological risk value, 426 risk areas were divided into 4 kinds of ecological risk area, and the ecological risk management game of the Giant Panda Habitat was proposed.
