摘　　要：基于2014年4月对三峡水库库首9条支流水环境监测分析结果,使用改进的综合营养状态指数法对其水体营养化状况进行分析和评价。结果表明：支流水体中的总氮含量范围为0.450-3.208 mg/L;总磷含量范围为0.001-0.329 mg/L;叶绿素浓度范围为0.737-184.610 mg/m3;透明度范围为0.2-4.5 m;高锰酸盐指数范围为1.032-5.451 mg/L,综合营养指数从库区下游到库区上游有递减趋势。Based on an analysis of the water environment monitoring results about each backwater area of nine tributaries of the Three Gorges Reservoir in April 2014, by means of the modified comprehensive nutrition state index method we analyze and evaluate the water eutrophication condition and conclude that total nitrogen content is about 0.450-3.208 mg/L. And total phosphorus content is about 0.001 - 0.329 mg/ L.The concentration of chlorophyll is about 0.737 - 184.610 mg/m3 ; water transparency is about 0.2 - 4.5 m.The scope of permanganate index is about 1.032- 5.451 mg/L, the comprehensive nutrition index has a decreasing trend in reservoir area from downstream to upstream.
