摘　　要：根据2008年1—12月澜沧江下游的漫湾水电站、大朝山水电站库区的水质监测资料,对水环境时空差异性进行了分析,结果表明:两库区水质特征变化趋势比较相似,季节性变化明显,两库区水体有机污染程度小,水体氮磷含量较高,属于中—富营养水平,总氮在秋季最高,冬季最低,总磷在夏秋季最高,春季最低。梯级水坝的形成对水体中总氮含量、有机污染的累积效应不明显。The spatiotemporal differences of the water quality of the reservoirs of Manwan and Dachaoshan Hydro- power Station were studied based on the water monthly monitoring data in 2008. The results showed that a similar trend of seasonal changes of water quality with less organic pollution was found between the reservoirs. The concen- trations of nitrogen and phosphorus in both reservoirs were high in a mesotrophic and eutrophic level. The total ni- trogen was high in the autumn and low in winter. The total phosphorus was high in both summer and autumn and low in spring. There was no significant difference in terms of TN, BOD5, COD, and DO.
