白定村农业小流域氮磷和重金属各项值都达到Ⅲ类水标准(生活饮用水等标准)。而标准中农业用水属于Ⅴ类水，说明该流域内农业用地对水流的污染不是很严重。氮磷含量水平的变化趋势基本上符合流域内的实际情况，但是流域中下游处于人类密集区，必定会对流域以及本项目的研究数据产生很大的干扰。因此，为了更准确的掌握本地面源污染的动态变化，需要对流域进行更加及时全面的监测。

The content of nitrogen,phosphorus and heavy metal in Bai - ding agricultural small basin were both reached the III water standard (Drinking water standard).However,agri-cultural water belongs to V in the standard.The research results showed that water pollution caused by agriculture was not very serious.The change trend of the content of nitrogen and phos-phorus level basically is accord with the actual conditions of the basin.But the middle and lower reaches of the basin is in the human concentrated areas,what will produce great interference to the research data of this project.Therefore,in order to grasp the dynamic changes of the local non-point source pollution is more accurate,it must be more comprehensive and timely monito-ring of the river basin.
