- Abstract:
-
Vulnerability refers to the ability of resisting natural disasters and human activities including economy, social development and ecological environment etc. In the process of rapid urbanization, using entropy method to determine the index weight and to establish the vulnerability calculation model, we analyzed the evolution of vulnerability in northwestern territories from 2004 to 2013 by constructing comprehensive evaluation system of vulnerability in northwestern territories. The results showed as follows. The vulnerability of the northwestern territories generally declined in last 10 years, the maximum decrease rates were 46.83% in Shanxi, 47.40% in Gansu, 29.84% in Qinghai, 45.95% in Ningxia and 24.62% in Xinjiang. The changes of vulnerability can be divided into a high vulnerability dominant phase (2004-2008) and low vulnerability dominant phase (2009-2013). And the vulnerability index of the regional disparity gap shrank. With respect to the subsystem features, the vulnerability of economy, social development and ecological environment presented the fluctuating decline. The economic vulnerability of the subsystem can be divided into rapid decline stage(2004-2008)and slow decline stage (2009-2013), the impact of ecological environment vulnerability increased, and the impact of economic vulnerability reduced significantly. It is the key to achieve sustainable development in northwestern territories which needs the comprehensive consideration of vulnerability and implementation plan to re-establish the decision support system.
