参考国内外相关研究成果，在全面掌握我国城市河湖水生态环境现状与问题的基础上，采用层次分析法、隶属度函数计算等分析方法，建立了城市河湖水生态系统的评价指标体系与评价标准，并以江苏省为例，利用历史数据以及监测资料，对城市河湖水生态环境现状进行了实证分析。实证结果表明，所构建的评价指标体系能够对城市河湖水生态环境进行较为全面的分析，可为城市河湖水污染综合治理和城市生态建设提供科学依据与实证参考。

In reference to the relevant research results at home and abroad and based on a comprehensive evaluation of the present situation and problems of the ecological environment of urban rivers and lakes in China, the analytic hierarchy process and membership function calculation method were used to establish the evaluation index system and evaluation standard for the ecological system of urban rivers and lakes. The evaluation index system was applied to analyze the ecological environment of rivers and lakes in Jiangsu Province according to the historical data and monitoring data of urban rivers and lakes. The results showed that the evaluation index system can conduct a comprehensive analysis of the ecological environment of urban rivers and lakes. Therefore, it can provide scientific basis and empirical reference for the comprehensive management of water pollution in urban rivers and lakes and ecological construction of urban areas..
