摘　　要：为评估渔业保护区的环境质量状况及富营养化水平,以全国渔业生态环境监测网数据为基础,运用综合营养状态指数法,对中国湖泊主要分布区域长江中下游3个保护区的富营养状况进行了评价。结果显示,梁子湖武昌鱼国家级水产种质资源保护区、鄱阳湖鳜鱼翘嘴红鲌国家级水产种质资源保护区、千岛湖国家级水产种质资源保护区综合营养指数分别为45.0、49.4、42.6,整体处于中营养水平,主要贡献因子是总磷和叶绿素a。Aiming to evaluate the eutrophication levels of three national aquatic germplasm conservation zones,which all located in the middle and lower Yangtze River,where most lakes were distributed too in China.The evaluation was based on comprehensive nutritional status index and the data used was from national fishery eco-environment monitoring network.The results showed that the comprehensive nutritional status indexes of Liangzi Lake Wuchang Fish National Aquatic Germplasm Conservation Zones,Boyang Lake Mandarin Fish and Topmouth Culter National Aquatic Germplasm Conservation Zones and Qiandao Lake National Aquatic Germplasm Conservation Zones,were 45.0,49.4 and 42.6,respectively,indicating all three conservation zones in mesotrophic level and the main contribution factors were total phosphorus and chlorophyll a.
