以桃庄河小流域桃庄河村下属的东沟村民小组所在的农田为代表,收集了不同雨强下不同类型农田中的地表径流,分析其中的污染物浓度,研究流域内面源污染特征;根据实测降雨资料,应用SCS模型估算了该流域内几种农田中的径流量。在此基础上估算了不同农田中的养分流失量,为流域农业面源污染的防控提供依据。 Taking the farmland of Donggou village subordinate affiliated to Taozhuanghe Village in the Taozhuanghe small watershed as the representative, the surface runoff of different types of farmland under different rainfall intensities was collected, and the pollutant concentration was analyzed to study the characteristics of the surface source pollution in the watershed. According to Measured rainfall data, estimated the runoff of several kinds of farmland in the basin using SCS model. Based on this, the amount of nutrient loss in different farmlands was estimated, which provided the basis for the prevention and control of agricultural non-point source pollution in the basin.
