Abstract
[Objective] The aim was to carry out dynamic assessment on ecosystem vulnerability in Dashanbao wetland. [ Method] Evaluation index system of ecosystem fragility in Dashanbao wetland was constructed by using analytic hierarchy process (AHP) , and dynamic assessment on ecosystem vulnerability in Dashanbao wetland from 2002 to 2008 was carried out based on vulnerable degree of ecosystem. [ Result ] The vulnerable degree of ecosystem in Dashanbao wetland from 2002 to 2008 was 0.560 0, 0.513 7, 0.516 4, 0.465 4, 0.476 0, 0.449 2 and 0.400 6, respectively, namely showing decreasing trend on the whole, and ecological system vulnerability transformed from moderate vulnera bility to mild vulnerability- Ecological environment quality of Dashanbao wetland was better at present. [ Conclusion] The study could provide basis for wetland restoration, protection, ecological environment planning and management.关键词
