摘　　要：畜禽养殖业产污系数是环境领域重要的基础数据,当前在选取产污系数上差异很大。文章通过分析国内不同畜禽的产污特点,将猪、鸡和牛的产污系数进行合理整合,系数简化,只须统计各畜禽的存(出)栏量,便可得出产污量,结合某大城市的养殖业进行验证和预测。案例预测结果表明:在畜禽种类中,根据确定的猪、鸡和牛的产污系数(COD,TN,TP),估算出该市产生粪污量最多的是牛,占该市主要畜禽粪便产生量的61.2%,其次是蛋鸡13.1%,猪12.3%,肉鸡6.3%,与目前文献中计算方法得出的结果基本一致。Pollutants producing coefficients of livestock breeding industry are the important basic data in the field of enviromnent assessment. However, the reported coefficients have a significant difference. This study analyzed the features of different domestic livestock pollutant production and suggested a new pollutants generation coefficients. It simplified the methodology of pollutant assessment on the farm. The suggested pollutant producing coefficients were verified using the related livestock data of a big city. And the results showed that, among the kinds of animals, catde had the most feces and it accounted for 61.2% of the total feces in the city. The rest in turn were layer for 13.1%, pig for 12.3%, broiler for 6.3%. The amount of pollutants calculated with simplified methodology fit well to the old one.
