摘　　要：根据辽河吉林段内的农业面源污染特征,结合流域气候特征、土地利用结构、人口分布、化肥农药施用量、水土流失状况等基础数据,采用多因子综合评价法,对辽河吉林段面源污染强度进行了评价,并对辽河吉林段的面源污染强度进行了区划。该结果对于厘清辽河吉林段面源污染来源、判断面源污染程度以及制定流域面源污染防治规划都具有重要指导意义。According to the agricultural non-point source pollution characteristics in Jilin section of Liao River, combined with fundamental data such as the basin climate characteristics, land use structure, population distribu- tion, pesticide and chemical fertilizer application rate, soil and water loss situation, non-point source pollution in- tensity in Jilin section of Liao river is evaluated using multiple factors comprehensive evaluation method, and is re- gionalized. The results have important guiding significance for Jilin section of Liao River to clarify the non-point pollution sources, judge the non-point pollution degree and make planning for prevention and control of watershed non-point source pollution.
