摘　　要：利用输出系数法计算汾河流域运城段非点源总氮(TN)污染负荷并分析其影响。汾河流域运城段非点源TN约为127.415×104t/a,其中农业化肥污染、农业人口生活污染及牲畜养殖污染非点源TN的贡献率较大,农业人口生活污染为最大来源。非点源污染是汾河流域运城段水环境质量的一个重要方面,对流域非点源污染的控制已刻不容缓。Aim to analyze the impacts on the water environmental based on the estimation of pollution load of total nitrogen emitted from the non-point sources in Yuncheng of Fen River basin.Methods the pollution load of total nitrogen and the proportion of the pollutants originating from the non-point sources in the area are discussed by employing the export coefficient modeling approach.Results The results show that the pollution load of total nitrogen from the non-point in the area amounts to 127.415×104 ton annually.The biggest source of non-point pollution including agricultural of chemical fertilizers,agricultural population pollution and livestock farming population,the top one is the agricultural population pollution.Conclusion pollution from non-point sources tends to be the significant factor affecting the water quality in Yuncheng of Fen River basin.Accordingly the control of the non-point source pollution in the area should be on the agenda very soon.
