摘要
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。
The farmland of Donggouvillager team in Taozhuangriver small watershed was as representative tostudy on the characteristics of non-point source pollution in the basin by collectingsurface runoffunder different rainfall intensity from dif-ferent types of farmland and analyzingpollutants concentration. SCS model was applied to estimate the farmland runoff by the measured rainfall data. The nutrient loss from the farmland was estimated on this basis to provide the basis for watershed a-gricultural non-point source pollution prevention and control.
