摘要

根据对曹娥江水系三典型支流2004年逐月进行水质监测分析，通过时空变异两个角度对这3条支流的水质进行了对比研究。结果表明：（1）以农业非点源污染为主的山溪性河流水质最好；以农业非点源污染为主的河谷平原河流水质次之，但水体富营养化现象比较严重；受工业废水和城市生活污水污染的支流河流水质最差，有机物和氮磷指标严重超标。（2）3条支流中4个化学指标（NO3^--N、NH4^＋-N、TP、CODMn）在各个雨期之间浓度变化具有十分相似的规律。NO3^--N浓度在丰水期较高，在枯水期较低；NH4^＋-N浓度在丰水期较低，枯水期较高；TP浓度各个雨期之间都变化不大，相对稳定；CODMn浓度在各个雨期之问存在变化，但都没有明显的规律。
