摘　　要：采用单项指标分析法和属性识别模型,对2017~2018年苏州市域各供水水源地水质进行了指标特征分析和综合质量评价分析.结果表明,苏州市域供水水源地水质整体情况良好,各水源地水质综合质量均为Ⅱ级,达到水源地水域功能标准,并且2018年的综合质量整体上要优于2017年,说明当地的保护及综合治理措施积极有效.高锰酸盐指数和氨氮是影响苏州市域供水水源地水质的主要因子.在水质综合评分的排名中,长江和尚湖水源地的水质排在前列,傀儡湖水源地居中,太湖水源地排名比较靠后;因此,太湖水源地仍然应当是当前水环境保护和关注的重点.Based on the single index analysis method and attribute recognition model,the water quality of each water supply source in from 2017 to 2018 was analyzed.The results showed that the overall water quality of water supply source areas in Suzhou was good,and the comprehensive quality of water quality of each water source was grade II,reaching the functional standard of water source area,and the comprehensive quality in 2018 was better than that in 2017,indicating that the local protection and comprehensive treatment measures are positive and effective.Permanganate index and ammonia nitrogen were the main factors affecting the water quality of Suzhou water supply source.In the comprehensive score of water quality,the water source of Shanghe lake and the Yangtze River was in the forefront,the water source of puppet lake was in the middle,and the water source of Taihu Lake was relatively low.Therefore,the water source of Taihu Lake should still be the focus of water environmental protection and attention.
