| 摘 要： | 运用压力-状态-响应模型和层次分析法构建生态安全评价指标体系,综合运用GIS技术及模糊物元分析方法对南京市仙林新市区建设前后(2003和2007年)的生态安全状况进行评价。结果表明,2003—2007年,仙林生态安全状况主要向2个方向发展,生态安全和不安全区域面积均有所增加,占区域总面积比例分别由9.6%和12.9%增加至22.3%和15.0%。由于各区域发展模式不同,生态安全状况区域差异明显。具体表现为仙鹤片区与白象片区生态安全区域面积明显增加,占研究区总面积比例分别由2.6%和3.9%增加至10.1%和9.3%;麒麟片区生态安全状况以临界安全为主,部分片区由临界安全状态向较安全状态转化;青龙片区生态安全状况变化不大。

| Abstract: | An eco-security assessment index system was established,using a pressure-state-response(P-S-R) model and the analytic hierarchy process,while eco-security levels of Xianlin District before(2003) and after(2007) its construction were assessed using the GIS technology and the fuzzy matter element analysis method in a comprehensive way.The ecological security in the Xianlin New Urban District in Nanjing was evaluated.It was found that the ecological security level of Xianlin developed in two directions.The are... |
