摘　　要：开展阳澄湖区域水污染现状调查研究是湖泊治理和合理利用水资源的基础。本文针对2022—2023年阳澄湖主要出入湖河道和湖体开展水质和浮游植物监测调查,分析入湖河道水质中氨氮、总磷、高锰酸盐指数和流量,以及湖体水质中总磷、氨氮、蓝绿藻、叶绿素a情况。研究结果显示,阳澄湖水质总磷来源主要分布在西南侧和北侧入河河流,污染源主要为集镇区生活源。为此,本文建议强化污水截流与收集,加快城镇污水收集管网特别是支线生活污水管网建设。Conducting research on the current situation of water pollution in Yangcheng Lake area is the foundation for lake governance and rational utilization of water resources.Conduct water quality and phytoplankton monitoring surveys on the main inflow and outflow channels and lake bodies in Yangcheng Lake from 2022 to 2023,analyze the ammonia nitrogen,total phosphorus,permanganate index and flow rate in the inflow channel water quality,as well as the total phosphorus,ammonia nitrogen,blue-green algae,and chlorophyll-a situation in the lake water quality.The results show that the total phosphorus source of Yangcheng Lake water quality is mainly distributed in the rivers flowing into the southwest and north sides,and the pollution source is mainly from the domestic sources in the town area.Suggest strengthening sewage interception and collection,and accelerating the construction of urban sewage collection pipelines,especially branch domestic sewage pipelines.
