Characteristic and Analystic Framework of Vulnerability of Social Ecological System of Lake Basin

Abstract:

This paper elaborates the structure succession, hierarchical charicteristic and function of lake basin social ecological system (SES),combining “Pressure-State-Response”(PSR) with “Exposure-Resilience-Adaptability” model,based on “Analytic Hierarchy Process” (AHP) for driver analysis, from risk (pressure), sensitivity, adaptability builds the analytical framwork of social ecological system vulnerability. The results show that lake basin social ecological system is a complicated giant system, which contains several subsystem and there exists the cross-scale association in structure and process among systems with different scales .The structure of lake basinis in constant succession, and different stage of which has different function structure and cross-scale interaction. Resilience, adaptability, transformability of lake basin social ecological system are the result of the interaction of pressure on the system and their sensitivity to it. The evaluation index system could consist of three element layers: risk (pressure), sensitivity, adaptability, the interaction among whch decide the vulnerabilities of the whole social and ecological system.
