Study on Index System of the Environmental Change and Ecological Security for a River Basin Based on DPSIR Model

摘要

[Objective] The research aimed to study index system of the environmental change and ecological security for a river basin based on DPSIR model.[Method] Based on considering each influence factor of the environmental change and ecological security for a river basin,DPSIR model as framework,the basic framework,principle and related method of index system of the environmental change and ecological security for a river basin under influence of the multi-level development were put forward.[Result] Index system of the environmental change and ecological security for a river basin based on DPSIR model included driving force indicator,pressure indicator,state indicator,influence indicator and response indicator.Each indicator type also had many sub-indicators.[Conclusion] The research provided theoretical support and method reference for assessment of the ecological security and execution of the ecological environment management for a river basin in China.
