摘　　要：本文通过对袁河沉积物中氨氮、总氮、总磷和COD(重铬酸钾法)含量的监测,分析袁河底泥污染物的分布规律,并通过同一断面袁河污染物与底泥中相应污染物含量的对比,研究底泥污染物的来源,由此得出除个别断面外,沉积物中污染物含量高的断面河水中的含量相应的也较高。对比袁河与太子河流域可知,袁河流域沉积物污染程度远低于太子河流域。这就为维持袁河河流生态健康,合理利用袁河水资源提供了依据。Based on the contents monitoring of ammonia nitrogen,TN,TP and COD in the sediments,the distribution of pollutants in the sediments along the Yuan River were analyzed.Through the contrast of pollutants contents between water and sediment in the same site,the sources of pollutants in the sediments were studied,from which it can be concluded that apart from individual sites,the concentrations in the river water are higher correspondingly where the contents in the sediments are higher.On the contrast of the pollution degree of the sediments between Yuan River and Taizi River it can be concluded that the degree in the Yuan River is much lower than in the Taizi River.Therefore,it can provide the basis to maintain the ecological health of rivers and make use of the water resources rationally along the Yuan River.
