摘　　要：根据福清市东张水库2014—2018年的水质监测数据,参照《地表水环境质量标准》(GB3838-2002),采用水质污染综合指数法、污染负荷比及综合营养状态指数法对东张水库水质污染程度及污染变化趋势进行分析,发现东张水库长期处在中营养状态,总磷、总氮污染负荷比排在前两位,是最主要的污染源。建议采取措施,降低氮、磷等营养盐的输入,逐步改善东张水库水质状况。Based on the water quality monitoring data of Dongzhang Reservoir in Fuqing City from 2014 to 2018,this paper refers to the“Surface Water Environmental Quality Standards”(GB3838-2002)and adopts the comprehensive index method of water pollution,pollution load ratio and comprehensive nutrition status index The analysis of Dongzhang Reservoir's water pollution degree and the trend of pollution changes revealed that Dongzhang Reservoir was in a medium-nutrient state for a long time,and the total phosphorus and total nitrogen pollution load ranked the top two than the total,and were the most important contributors.Measures should be taken to reduce the input of nutrients such as nitrogen and phosphorus,and gradually improve the water quality of Dongzhang Reservoir.
