摘　　要：以天津市境内的于桥水库流域为例,采用层次分析法围绕现阶段区域内农业面源污染防治主要处理技术及典型模式进行评价优选,得出多级AO为流域内农村生活污水治理首选技术;选取"种养一体"模式下的典型规模场,进行样品测试分析得出畜禽粪污还田的稀释配比范围在1∶8~1∶20之间;并利用氮养分平衡方法分析得出流域内各乡镇的畜禽粪污土地承载能力。研究成果能较为全面地指导类似流域的农业面源污染治理,同时亦为畜禽养殖行业发展提供规划依据。Taking the typical watershed of Tianjin Yuqiao reservoir as the research area,the comprehensive treatment technologies of rural domestic sewage and large-scale livestock and poultry breeding were analyzed.The analytic hierarchy process showed that the technology of multilevel AO was the preferred for rural domestic sewage treatment in the basin.The dilution ratio range of livestock manure returning to the fields was analyzed by the typical samples,and its values was in the range of 1:8-1:20.By means of nitrogen nutrient balance method,the land carrying capacity of livestock and poultry waste was obtained in each town of the basin.The research results can direct the treatment of agricultural non-point source pollution in similar basins,and provide planning basis for the development of livestock and poultry breeding industry.
