| 摘 要： | 以图们江流域下游敬信湿地生态安全评价为目的,基于压力-状态-响应（PSR）概念模型,选取典型性景观生态学和人文经济等12个指标,构建了湿地生态安全评价指标体系;采用专家打分法确定了各个指标的现状值,结合层次分析法对评价指标赋予权重,最终使用综合评价法对敬信湿地进行了生态安全评价.结果表明,敬信湿地的生态安全度在5.810左右,处于预警状态,急需加强对湿地的保护与管理.

| Abstract: | To evaluate the ecology safety assessment,we select 12 factors of typical landscape ecology and human economy to build the wetland ecology safety system,based on the Pressure-Status-Response（PSR） concept model,and use the experts＇ evaluation index combined with AHP evaluation to give the weight of the final comprehensive evaluation.The result shows that the safety of Jingxin wetland ecology is about 5.810,at the status of alert and the need of strengthening the protection and management of this wetland is an urgent issue. |
