摘　　要：根据2011~2013年桓龙湖水库总氮、总磷、生化需氧量等15项指标的监测,及运用综合营养状态指数法对近3年水质变化趋势进行分析,结果表明：桓龙湖水库水质基本符合《地表水环境质量标准》（GB3838-2002）规定的Ⅱ类标准,水质较好,总氮、总磷浓度超标;2011~2013年水质逐年变差,水库下游水质优于上游;富营养化程度为中营养,有富营养化趋势.分析了水库的污染源,从社会经济调控、水污染控制、生态系统调控、生态安全管理四个方面提出了桓龙湖水库的保护措施.According to monitoring 15 indexes including Total Nitrogen,Total Phosphorus,Biochemical Oxygen Demand of Huanlong Lake Reservoir from 2011 to 2013,and analysing the water quality change trend with the comprehensive eutrophication state index in nearly 3 years,the results indicated that： the water quality of Huanlong Lake Reservoir was basically up to the standard II of ＂Environmental quality standards for surface water＂and it was fairly good,TN and TP exceeded that standard; water quality from 2011 to 2013 got worse year by year,water quality of the reservoir downstream better than that of the upstream; the degree of eutrophication was mesotropher and the reservoir had eutrophication trend. Reservoir pollution sources were analyzed and some protection measures about Huanlong Lake Reservoir were put forward considering the social and economic regulation,control of water pollution,ecosystem regulation and ecologicalsecurity management these four aspects.
