摘　　要：对溧水区6座中型水库2011—2021年间的水质状况及富营养化状况作了分析评价。主要污染指标趋势分析表明水库氮磷质量浓度有缓慢下降趋势,NH3-N质量浓度在2018年前为跳跃式变化,2018年以后明显下降,与水环境治理措施的推进、流域内农村生活污染物减少有关,针对这些情况,研究提出了有针对性的对策和措施。The water quality and eutrophication status of 6 medium-sized reservoirs in Lishui District from 2011 to 2021 were analyzed and evaluated.The trend analysis on the main pollution indicators indicates that the nitrogen and phosphorus contents in the reservoirs have been decreasing slowly.The ammonia nitrogen content suddenly changed before 2018 and significantly decreased after 2018,which is related to the promotion of water environment management measures and reduction of rural area domestic pollutants within the basins.According to the situation,targeted solutions and measures were proposed.
