摘　　要：利用畜禽养殖数据,估算了2013年秦皇岛市畜禽粪便产生量及污染物量,并根据耕地污染负荷量,评价了畜禽养殖的环境风险。结果表明,2013年秦皇岛市农田负荷量平均值为35.66t/hm^2,畜禽养殖环境污染风险指数为0.88,预警级别为Ⅲ,除海港区、北戴河区、昌黎县稍有影响外,其它各县(区)均已对环境构成潜在威胁。Using the data of livestock and poultry breeding,the output of livestock manure production and pollutants of Qinhuangdao in 2013 was estimated,in addition,the load capacity of cultivated land pollution,the environmental risk assessment of livestock and poultry breeding in Qinhuangdao city was also evaluated.Results show that in 2013,the average load capacity of livestock manure in the city was 35.66t/hm^2,and the environmental pollution risk index was 0.88,with a warning level III.It reveals that the livestock breeding in all counties（districts）except the Haigang District,Beidaihe District and Changli County have posed a potential threat to the environment.
