Agricultural non-point source has become an important source of water pollution in some regions. In order to study the agricultural non-point source pollution prevention and control countermeasures in Hefei,this paper uses inventory analysis,cluster analysis and other methods to identify the agricultural non-point source pollution prevention and control priority areas on the basis of analyzing the spatial characteristics of agricultural non-point source pollution. The results showed that priority areas for agricultural non-point source pollution control in Hefei were Changfeng County,Feidong County and Feixi County;the key control areas were Yaohai District,Luyang District,Shushan District and Baohe District;the general control areas were Lujiang County and Chaohu City. Aiming at the characteristics of agricultural non-point source pollution in different regions,the paper puts forward the countermeasures of prevention and control according to the principle of "one area one policy".%农业面源已经成为部分区域水体污染的重要来源.为研究合肥市农业面源污染防控对策,本文采用清单分析、聚类分析等方法,在分析农业面源污染空间特征的基础上,识别出农业面源污染防控优先区域.结果显示,合肥市农业面源污染优先控制区为长丰县、肥东县和肥西县;重点控制区为瑶海区、庐阳区、蜀山区和包河区;一般控制区为庐江县和巢湖市.针对不同区域农业面源污染特点,以"一区一策"为原则,提出有针对性的防控对策.
