针对我国北方农村中小流域缺乏实地水文监测数据的现状,借助实地调查与农村统计年鉴,利用输出系数法计算浑河上游地区大苏河乡10个行政村的农业非点源污染负荷值;在验证实地监测数据与污染负荷值间相关性的同时,利用等标污染负荷法对各个污染源作评价,得到同一尺度上具有可比性的等标污染负荷值;利用聚类分析将这10个行政村划分为4类农业非点源污染负荷类型,分析其污染负荷特点.污染源评价结果显示,大苏河村生活污染和畜禽粪便污染负荷均最大,小苏河村农田化肥污染源负荷量最大.由聚类分析可知,所划分4个类别等标污染负荷平均值分别为51. 05 .95. 80 .236. 41 、185. 69 m~3,表明不同区域农业非点源污染的相对差异明显.

Aiming at the problem of lack of water monitoring data of medium and small river basins in the countryside of North China, a project was carried out based on the findings of field surveys and the local statistics yearbooks, to calculate agricultural non-point source pollution load of 10 administrative villages in Dasuhe Township, using the export coefficient method, and in verification of the data obtained in the field survey and their relationship with pollution load, evaluation of the pollution sources was done, using the equiscalar pollution loading method, to obtain comparative equiacalar pollution loads on the same scale. Cluster analysis of the findings and results were obtained. The 10 villages were divided into 4 types in terms of agricultural non-point source pollution, and characteristics of each pollution source was analyzed. Results of the evaluation show that the Dasuhe Village ranked first in contribution to the load of domestic pollution and livestock dejecta pollution, and the Xiaosuha Village did in contribution of the load of farmland chemical fertilizer pollution. The cluster analysis also demonstrates that the mean value of the equiscalar pollution loads of the 4 types of agricultural nonpoint source pollution was 51.05,95.80,236.41,185.69 m~3, which indicates that relative differences are exsiting between villages in agricultural non-point source pollution.
