Abstract:

Taking the Longhe ecological restoration demonstration area in Pingguo County，Guangxi Autonomous Region as an example，on the basis of result examination and expert′s consultation，an index system was constructed，and each index’s weight value was analyzed by AHP.Using an index model the assessment of the rocky desertification mountain compound ecosystem was made. AHP analysis results showed that the weight values of vegetation coverage，human activity intensity，species diversity，material life index，rocky desertification degree，water and soil erosion degree were larger than other indexes，indicating that all these factors play an important role in the compound ecosystem.The index model assessment results suggested that the comprehensive quality of the rocky desertification mountain compound ecosystem was rather bad before constructing the ecological restoration demonstration area.The vegetation coverage，the agricultural production conditions and the living standard of human in the system were promoted after the ecological restoration demonstration area was constructed，the comprehensive quality of the compound ecosystem was improved，and the social subsystem，the economic subsystem and the environmental subsystem ran more efficiently.

Key words: Pingguo County, Guangxi Autonomous Region, rocky desertification, mountain compound ecosystem, assessment
