| 摘 要： | 牧羊河是松华坝水库上游的一条重要支流,其水质质量直接影响到松华坝水库的水质。通过牧羊河上、中、下游不同断面的水质监测和分析,结果表明:(1)牧羊河流量及其变异系数变化均是上游<中游<下游;(2)牧羊河的pH值变化较小,变化范围在7.5～9.0之间;(3)牧羊河水质化学需氧量(COD)变化幅度较大,上游和中游化学需氧量变幅大于下游,下游变化较为平稳;(4)丰水期牧羊河水质总氮(TN)变化幅度大,枯水期总氮(TN)变化渐趋平稳,其数值逐渐减小;(5)牧羊河水质总磷(TP)含量随流量的增大而升高,上中下游水质总磷(TP)含量变化有一定的延迟效应;(6)牧羊河水质化学需氧量可以较敏感地反映水质状况,总氮反映流域环境变化,总磷反映流域水土流失情况。
