摘　　要：为了解近10年来阳宗海的水质变化特征及砷污染事件发生后砷的治理成效,对2012—2021年的水质监测数据进行了研究,结果发现:化学需氧量、总磷、总氮、砷等主要监测指标削减明显,综合污染指数和综合营养状态指标呈显著下降趋势,说明近10年来阳宗海水质有所改善,特征污染物砷治理成效显著。In order to understand the characteristics of water quality changes in Yangzonghai Lake in the past 10years and the effect of arsenic control after the arsenic pollution incident,the water quality monitoring data from 2012 to 2021 were studied,and it was found that the main monitoring indicators such as chemical oxygen demand,total phosphorus,total nitrogen,and arsenic decreased significantly,and the comprehensive pollution index and comprehensive nutritional status index showed a significant downward trend,indicating that the water quality of Yangzonghai Lake has improved,and the treatment of characteristic pollutant arsenic has achieved remarkable results in the past 10 years.
