摘　　要：根据2008年1-12月对澜沧江下游的漫湾和大朝山水电站库区的水环境监测结果，应用浮游植物指示法、地表水资源质量标准评价、经验TLI法评价、藻类现存量指标法对影响水体富营养化的水环境指标进行了分析。结果表明，两库区水体中，营养盐指标总体处在一种高含量水平，大朝山和漫湾库区水体总氮浓度年变化范围分别为0．345-1．880mg／L和0．340～1．743mg／L，总磷浓度年变化范围分别为0．019—0．139mg／L和0．015—0．111mg／L。TLI综合指数评价表明两库区水体处于贫营养水平。Phytoplankton indication method, algae stock index method, and TLI method were applied to assess the eutrophication state of the reservoirs of Manwan and Dachaoshan hydropower plants of the downstream of Lancang River. The monthly water monitoring data of 2008 was used. The results showed that the nutrition indices in the two reservoirs were high. The yearly changes of TN in Dachaoshan and Manwan were between 0. 345 - 1. 880mg/l and 0. 340 - 1. 743 mg/l respectively. The changes of TP of the two reservoirs were 0. 019 - 0. 139 mg/l and 0. 015 -0. 111 mg/l respectively. The TLI index indicated that both reservoirs were still in dystrophic condition.
