| 摘 要： | 结合我国非点源污染监测资料少的实际情况,利用我国现有的水文站降雨资料和水质资料,提出了一种简便易用的流域非点源污染负荷估算方法——降雨量差值法。与传统的径流分割法相比,降雨量差值法能利用现有水文水质资料而无需增加监测项目,即可对流域非点源污染负荷作出估算,计算过程简单,结果合理。

| Abstract: | The prediction of the non-point source pollution (NSP) load is becoming increasingly important in water pollution controlling and planning in watershed.Considering the monitoring data shortage of NPS in China,a practical estimation method of non-point source pollution load-rainfall deduction method is established based on the rainfall and water quality data existent in China.Compared with runoff division method,the rainfall deduction method is characterized with simple calculation and a reasonable result but without additional NSP monitoring data. |

| Keywords: | non-point source pollution load prediction rainfall deduction method runoff division method |
