摘　　要：根据升钟水库近5年的水质监测数据,探讨了库区的水质现状和营养盐变化趋势及污染治理措施成效。数据显示,与2006年相比,升钟水库营养状况由轻度富营养向中营养发展,2014~2018年稳定在中营养状态。2014年起,TP、TN快速下降,受上游输入污染、旅游污染等影响,TP2016年开始上升,TN2017年开始上升;受农业面源污染、地表径流等因素影响,CODMn2015年起呈持续上升趋势。升钟水库的水污染治理成效显著,但仍需采取有力控制措施,防止水体向富营养化发展。Based on the water quality monitoring data of the Shengzhong Reservoir in recent 5 years, the water quality status and the variation trend of nutrient salts in the reservoir and the effectiveness of pollution control measures are discussed. The data show that compared with 2006, the nutritional status of Shengzhong Reservoir is developed from mild eutrophication to mesotrophication and remains mesotrophication during 2014~2018. The TP and TN declined rapidly since 2014. However, under the influence of upstream pollution input, tourism pollution, etc., the trend of TP turned to rise at 2016 and TN started to increase at 2017. The CODMn showed an upward tendency since 2015 due to factors such as agricultural surface pollution and runoff. The water pollution control of Shengzhong Reservoir has achieved remarkable results, but there still remains a need to take effective control measures to prevent the surge of eutrophication in water bodies.
