摘　　要：为系统地研究三峡库区悬浮泥沙与营养盐、有机污染物浓度关系，更有效地控制水污染，在2002年9月至2003年6月和2004年7～9月，长江上游水环境监测中心对三峡库区水质与悬移质泥沙进行同步监测。介绍了水质采样点的分布情况和水样分析方法。对水样中的N、P污染成份及COD进行了分析。结果表明：三峡库区水体中CODMn的浓度受水土流失与点污染源的影响较大，TP浓度受水土流失的影响较大；悬移质泥沙对CODMn和TP的影响大，对TN的影响相对较小。In order to make a systematic investigation on the relation of suspended sediment and the concentration of nutrient salt,organic substance to more effectively control water pollution,from September,2002 to June,2003 and from July,2004 to September,2004,the Upstream Yangtze River Water Environment Monitoring Center carried out synchronous measurement on water quality and suspended sediment in TGP reservoir.This paper introduces the distribution of sampling points and water sample analysis method and analyzes pollution components of N,P and COD in water sample.The analysis result demonstrates that COD_(Mm) concentration in water of TGP reservoir has close relation with soil-water loss and point pollution sources,TP concentration has close relation with soil water loss,the suspended sediment has large influence on COD_(Mm) and TP,but comparably less influence on TN.
