Study on Integrated Evaluation of Urban Ecosystem Health
An evaluation method of urban ecosystem health and its application were emphatically discussed, in which the entropyweighing method was employed to give indexes weight, and the fuzzy mathematics method is utilized to establish the evaluation model. Subsequently, the situation of urban ecosystem health in Chongqing was selected as a study case, and the ecosystem health towards Chongqing, Beijing, Tianjin and Shanghai was crosswise evaluated, finding that the above-mentioned four cities were all situated in sub-healthy state. Also, a longitudinal evaluation of the ecosystem health of Chongqing from 2001 to 2004 was carried out, showing that the condition of urban ecosystem health was developing from sub-healthy state to healthy state. Finally, the present conditions of ecosystem health state of nine districts in Chongqing Metropolis were investigated, and the rank division of ecosystem health was presented in virtue of GIS-based technology. Thus, an order of the state of ecosystem health was illustrated as: Yubei ＞ Nanan ＞ Yuzhong ＞ Banan ＞ Jiulongpo ＞ Jiangbei ＞ Shapingba ＞ Dadukou ＞ Beibei.
