城市生态安全评价指标体系与评价方法研究

A STUDY ON INDICES SYSTEM AND ASSESSMENT CRITERION OF ECOLOGICAL SECURITY FOR CITY

从城市生态安全的内涵出发 ,根据压力 (pressure) 状态 (state) 响应 (response)模型 ,从资源环境压力、资源环境状况、人文环境响应 3个方面构建了一个 4层次的城市生态安全评价指标体系 .在此基础上建立了一个综合评价模型 ,并以此对北京、上海、广州、深圳、大连、天津、南京 7大城市进行了分析 .评价结果与实际情况基本相符 ,说明本研究所建立的城市生态安全的评价指标体系和评价方法是可行的 .

Firstly some remarks are made on the concept of urban ecological security. On the basis of the Pressure-State-Response Model, a 4-layer indicator system of urban ecological security is put forward, which includes the urban resource and environment pressure, the state of urban resource and environment and the human social response. And then, this model is used to evaluate the urban ecological security about Beijing city, Shanghai city, Guangzhou city, Shenzhen city, Dalian city, Tianjin city and Nanjing city. The evaluation results are basically consistent to the fact of those cities, which indicates this urban ecological security indicators and evaluation approach are feasible to some extent.
