摘　　要：[目的]评价开县大中型水库（鲤鱼塘水库、三汇水库、龙安水库）的营养状态.[方法]利用2011 ～2013年鲤鱼塘水库、三汇水库、龙安水库3个水库的监测数据,采用综合营养状态指数法对3个水库的营养状态进行分析评价.[结果]三汇水库和龙安水库部分年份轻度污染,鲤鱼塘水库全年水质均为营养状态良好;龙安水库和三汇水库总氮和总磷均有部分年份劣于《地表水环境质量标准》（GB3838-2002）Ⅲ类水质标准,有些年份满足V类水质标准.[结论]该研究为政府制定污染物防治措施提供理论依据和决策参考.[Objective] The research aimed to evaluate the nutritional status of large and medium-sized reservoirs （Liyutang reservoir,Sanhui reservoir and Longan reservoir） in Kaixian.[Method] Using the monitoring data of three reservoirs from 2011 to 2013,the nutritional status of three reservoirs were analyzed and evaluated by comprehensive nutritional state index method.[Result] The water quality of Sanhui reservoir and Longan reservoir were mild pollution in partial years,and the water quality of Liyutang reservoir was good nutritional status in the three years.The TN and TP of Longan reservoir and Sanhui reservoir were intferior to Ⅲ water quality standard of Surface Water Environmental Quality Standard （GB3838-2002） in partial years,in some years to meet V water quality standard.[Conclusion] The study provides the theoretical basis and decision reference for making pollution prevention measures of the government.
