降雨-径流与非点源污染物浓度及流失量关系分析——以铁岭市柴河水库上游流域为例

以铁岭市柴河水库上游集水区域为研究对象,利用铁岭市柴河堡水文站降雨时节实测的暴雨径流数据、泥沙数据、污染物浓度数据进行分析,侧重研究降雨时节暴雨径流量与主要污染物浓度及污染物瞬时流失量之间的关系,以期为柴河流域农业非点源污染控制提供参考。研究结果表明:暴雨期内,非点源污染物浓度及瞬时流失量与径流峰值几乎同步出现,它们之间存在着非常密切的关系。

Analysis on Relations of Rainfall-Runoff and Non-Point Pollution Concentration and Loss Amount——Taking Upper Chaihe Reservoir River Basin in Tieling as Example

Taking upper Chaihe Reservoir River Basin in Tieling as study object, this paper analyzed the truth data of storm runoff, silt and pollution concentration, studied their relations in rainy season, so as to take reference for agriculture non- point pollution control of Chaihe River Basin. The results show that during storm period, non - point pollution concentration and momentary toss are co - occurence with the peak value of runoff, their relations are very closely.
