对云南大理洱海流域17个乡镇进行了等标污染负荷法分析。结果显示,喜洲镇农村生活污染负荷最大,右所镇畜禽粪便和农田化肥污染源负荷均最大;聚类分析法分析结果显示,所划分的4个类别等标污染负荷平均值分别为293.43、511.96、865.59和1104.75 m3,表明不同区域农业非点源污染的相对差异明显。根据流域面源污染的3种主要类型提出了相应的防控对策。

The agricultural non-point source pollution has become the most important factor of water pollution.The one-standard pollution load method of analysis in 17 towns along Erhai showed that Xizhou＇s rural life pollution was the head,and Yousuo＇s livestock manure and chemical fertilizer were the largest sources of pollution load.Cluster analysis results showed that the average of one-standard pollation load of the divided four types was 293.43,511.96,865.59 and 1104.75 m3,respectively,indicating that the relative differences of the agricultural n...
