| 摘 要： | 2004年夏季,对受三峡水库蓄水影响的12条次级河流库湾夏季水体营养化程度进行了调查。DO含量范围在2.20~10.1 mg/L;透明度范围在0.1~1.0 m;CODMn范围在1.60~9.79 mg/L;TN范围在0.72~5.27mg/L;TP范围在0.013~0.369 mg/L;叶绿素a范围在1.54~20.0 mg/m3。综合营养状态指数法评价的结果表明,各条次级河流的综合营养状态指数范围为39.2~69.2,其中8条河流达到富营养化水平,4条中营养。运用模型预测了三峡水库175 m蓄水后叶绿素a含量,范围在8.73~33.6 mg/m3,其中10条支流达到富营养化水平,2条为中营养。表明三峡水库支流水体富营养化程度将有加重趋势。

| Abstract: | Water quality of tributaries in Three Gorges Reservoir were investigated in 2004 summer.DO,SD,CODMn,TN,TP and Chla ranged from 2.20~10.1 mg/L,0.1~1.0 m,1.60~9.79 mg/L,0.72~5.27 mg/L,0.013~0.369 mg/L,1.54~20.0 mg/m3 respectively.Utilizing the method of integrated nutrition state index,it assessed the trophic states degree of tributaries.Integrated nutrition state index ranged from 39.2~69.2.In all of the studied tributaries,8 tributaries are eutropher,4 are mesotropher,respectively.The eutrophication trend i... |
