摘　　要：基于对浊漳河水系三典型支流2008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河谷平川河流水质最好;以农业非点源污染为主的高山峡谷河流,由于受到农业活动的影响,水质相对较差;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。②3条支流中4个化学指标(NH4+-N、TN、TP、CODMn)在不同水域、不同季节具有明显差异。以农业非点源污染为主的河流氮营养盐浓度在丰水期较高,在枯水期较低,TP浓度和CODMn浓度在各个雨期之间变化不大,且相对稳定;以点源污染严重的河流氮营养盐浓度在枯水期最高,在丰水期最低,个别断面TP和CODMn污染表现突出。In 2008, water quality parameters were monthly monitored in three tributaries of Zhuozhang River system, and spatial-temporal variations were compared among those rivers. The results showed that. ①The river dominated by agricultural nonpoint pollution through agricultural plain had best water quality, the river dominated by agricultural nonpoint pollution through alpine-valley had relative poor water quality which influenced by the agricultural activities, and the river dominated by industrial and domestic waste water had worst water quality with organic matter and indicators of nitrogen and phosphorus seriously exceed standard. ②Four chemical parameters of including NH4^ ＋-N,TN,TP and CODM, in three tributaries had significant differences in different seasons. Nitrogen concentrations of the river dominated by agricultural nonpoint pollution were highest in wet season and were lowest in dry season. TP and CODM. concentrations were relatively stable, and had little variation among various rain periods. Nitrogen nutrient concentrations of the river dominated by point serious pollution were highest in dry season and were lowest in wet season. TP and CODMn pollution of individual monitor section were relatively obvious.
