摘　　要：立足天津市滨海新区大港农业背景情况,采用适宜的方法,分别从种植业、畜禽养殖和水产养殖业三方面分析非点源污染物排放量。结果表明:2010年大港地区农业非点源主要污染物COD排放量为377.67 t,氨氮排放量为72.33 t,畜禽养殖排放的污染已占农业非点源污染的一半以上。在此基础上,分别从优化畜禽养殖的养殖模式、种植业科学施用化学品、水产养殖合理投放饲料等方面提出了大港地区农业非点源污染控制的对策。With respect to rainfall runoff from farmlands, manure from livestock and poultry bree-ding, aquiculture waste from agricultural area, the situation of these agricultural non-point sources （NPS） pollution was introduced in Dagang area of Tianjin in 2010. The results showed that： 2010 Dagang agricultural non-point source emissions of major pollutants COD was 377.64 t, ammonia was 72.34 t. Feasible countermeasures, such as livestock breeding patterns, rational fertilization in farmland, reasonable feeding in aquaculture feed, for Agricultural NPS pollution controlling in Dagang area were provided in management and engineering ways.
