摘　　要：通过监测何坊水库丰水期和枯水期的水质现状,选择叶绿素a、TP、TN、COD、透明度5个指标,采用评分法和营养状态指数法进行库区富营养化的评价,研究表明水库水体已处于中营养向富营养过渡阶段.在分析了水库富营养化成因的基础,提出了水库水资源的保护措施.Based on the monitoring of water quality in Hefang Reservoir during the high water period and low water period,we choose such evaluation indices as chlorophyll a,total phosphorus（TP）,total nitrogen（TN）,chemical oxygen demand（COD）,and transparency to evaluate the reservoir eutrophication situation by means of scoring method and nutrition state index.The results show that the average rating values are more than 40 points,and the TP is obviously beyond the standard.Therefore the reservoir is changing from mesotrophic to eutrophication.Based on the analysis of the causes of reservoir eutrophication,we proposed some protecting measures to control the reservoir eutrophication and protect the water environment.
