摘要
以PSR模型和"五水共治"治水模式为基础,从治污、防洪、排涝、供水、节水和社会经济6个方面选择指标,建立城市水生态安全评价指标体系,对城市水生态安全状况进行定量分析。采用专家评分的层次分析法对评价指标赋权,采用综合指数法对临海市水生态安全状况进行综合计算;最后根据计算结果评价临海市水生态安全状况。结果表明,临海市水生态安全状况随"五水共治"治水模式的推进逐渐得到改善。
Based on the PSR model and the mode of co-governance on five water categories, the indices involving sewage treatment, flood control, drainage, water supply, water conservation, and social economy were selected to establish an urban aquatic ecological security evaluation system, which was used to quantitatively analyze the status of urban aquatic ecological security. The index weight was determined by using the AHP method based on expert evaluation, and the comprehensive index method was used to calculate the status of aquatic ecological security of Linhai City. Based on the calculation results, the status of aquatic ecological security of Linhai City was evaluated. Results of the study show that the status of aquatic ecological security of Linhai City has improved under the mode of co-governance on the five water categories.
