摘　　要：为了解永城市采煤塌陷区水质状况,以永城市日月湖为研究对象,采用单因子评价法和综合营养状态指数法TLI(∑)对2020年11月至2021年9月永城市日月湖进行了水质监测并对其进行了水质和富营养化评价。结果表明:永城市日月湖水质在枯水期和平水期高锰酸盐指数、氨氮、总磷、总氮等表现为无污染状态,丰水期总磷为低污染状态,在枯水期、平水期和丰水期水质均处于中度富营养化状态。水质的提升与保护是采煤沉陷区修复和治理的重要部分,根据评价结果,为日月湖水质改善提出了补充外在水源,打捞湖面污染物,建立生态防护栏、生态沟渠等防治措施。In order to understand the water quality of coal mining subsidence areas in Yongcheng City,this paper takes Riyue Lake in Yongcheng city as the research object.The water quality of Riyue Lake in Yongcheng city from November 2020 to September 2021 was monitored by single factor evaluation method and comprehensive nutritional state index method TLI(∑).The results were evaluated for water quality and eutrophication.The results show that the water quality of Riyue Lake in Yongcheng city is in a pollution-free state in dry seasons and peacetime,and the permanganate index,ammonia nitrogen,total phosphorus and total nitrogen are in a low pollution state in wet seasons.The water quality is in the state of moderate eutrophication in dry seasons,normal seasons and wet seasons.The improvement and protection of water quality is an important part of the restoration and treatment of coal mining subsidence areas.According to the evaluation results,this paper puts forward some prevention and control measures for the improvement of water quality.
