| 摘 要： | 根据压力-状态-模型构建了城市生态安全评价指标体系，基于物元分析建立判定模型评价城市生态安全，采用层次分析法确定指标权重，并以合肥市为例进行生态安全评价，得出合肥市生态安全水平的等级。评价结果基本与实际相符，能较客观反映各评价指标及合肥市城市生态安全水平，说明建立的物元判定模型是可行的。

| Abstract: | According to PSR framework, this paper constitufes indexes system of ecology security assessment of the city. On matter-element, assessment model is set up. This paper applies this model to assess ecology security of Hefei. With calculation of weight adopting the AHP, the level of the ecology security of Hefei is calculated on the degree of relation between the matte-element and every grade. Study result shows that matter-element assessment model can reflect the level of city ecology security objectively and accurately. Therefore, the model of matter-element assessment is feasible. |
