- Abstract:
- The health of urban ecosystem is related to the sustainable development of cities. The study of the urban ecosystem health assessment could provide the criterion for formulating schedules about the urban development and the protection of ecological environment. We took the vigor of urban ecological system, organization structure, restoring force, service function and dynamic change as the healthy criterion for the urban ecological system and applied the criterion to Chongqing City. This paper ensured the weight factor of the criterion, and adapted fuzzy mathematical evaluation method to analyze the ecological system health condition of Chongqing City from 2004 to 2011 by using principal component analysis. On the other hand, in order to identify how well the ecosystem of Chongqing City is, in corresponding, we chose other three cities, Chengdu, Shanghai and Qingdao to compare their ecosystem health condition in 2011 with Chongqing. The comparison result showed that Chongqing’s ecosystem health condition was growing better yearly from 2004 to 2011; in 2011, at the evaluation of these four cities’ ecosystem health condition, Shanghai is the best, followed by Chengdu and Chongqing, Qingdao City is relatively the worst. At last, this paper gave some suggestions for how to improve the urban ecosystem health condition.
