摘　　要：分析了贺兰县农村非点源污染现状,发现污染主要以种植业的化肥、农药,养殖业的禽畜粪便、残余饵料、药物,农村的生活垃圾和污水,企业的固体废弃物等为主。在此基础上构建了贺兰县农村非点源污染防治模式,并将其分为种植业非点源污染防治模块、养殖业非点源污染防治模块、农村生活非点源污染防治模块、农村工业非点源污染防治模块,4个子模块既相对独立,又互为补充,可确保贺兰县不同村落有不同的良性发展模式。This paper analysed the situation of rural non-point source pollution of Helan County and found the main pollution mainly come from chemical fertilizers, pesticides, aquaculture livestock dung, residual food, drugs, rural living garbage and sewage, as well as solid waste of enterprises. Then the control model of rural non-point source pollution composed of four non-point source pollution prevention sub-modules including non-point source pollution prevention and control module for crop cultivation, non - point source pollution prevention and control module in aquaculture, non-point source pollution prevention module for rural life as well as non-point source pollution prevention module for rural industry were set up. These sub-modules are relatively independent and complement each other to ensure that different villages have different healthy development model of Helan County.
