摘  要:
水生态安全建设对维护人类正常活动和生态系统的可持续发展具有重大意义。本文基于"驱动力-压力-状态-影响-响应"(DPSIR)模型建立了许昌市的水生态安全评价体系,对许昌市2005—2014年的基础数据进行了筛选,采用熵权法对筛选出的19个评价指标进行赋权,利用综合评价指数分析评价许昌市的水生态安全,评价结果表明未来许昌市的水生态安全仍有上升的可能。

摘  要:
Water ecological security construction is significant for the maintenance of human normal activities and sustainable development of ecosystem. In the paper,water ecological security evaluation system based on ‘Driving forcePressure-State-Influence-Response'( DPSIR) model in Xuchang is established. Basic data are selected in Xuchang from2005 to 2014. Entropy weight method is adopted for empowering 19 selected evaluation indexes. Comprehensive evaluation index is utilized for analysis and evaluation of water ecological security in Xuchang. The evaluation results show that the water ecological security of Xuchang in the future still can be improved.
