| 摘 要： | 采用人工模拟降雨的方法,以5种不同的降雨强度研究浙江省临安市青山湖流域内荒坡的产流产污特征.结果表明,降雨径流总量与降雨强度呈正相关,相关系数达到0.873 2;径流中平均含沙量浓度雨强关系不显著,不同污染物产污浓度大小排序为COD>TN>TP>水溶性磷;雨强越大,污染物浓度越小,说明雨水对污染物浓度有稀释作用;不同污染物的次产污模数与雨强呈正相关,相关系数均在0.9以上,说明降雨强度越大,产生的污染也越大.

| Abstract: | A field experiment under simulated rainfall was carried out to assess the characteristics of pollution and runoff yield at five different rainfall intensities on barren grassland slope in Qingshan catchment,Lin'an City,Zhejiang Province.Results showed that runoff volume was positively correlated with rainfall intensity and the correlation coefficient was 0.873 2.Sediment concentration in runoff was not significantly correlated with rainfall intensity.Pollutants ranked in the descendant order of COD,TN,TP,an... |
