摘　　要：以全国"资源节约型"和"环境友好型"社会建设综合配套改革实验区武汉城市圈为研究区域,结合区域内畜禽饲养量、畜禽排污量以及有效耕地面积,对各市畜禽粪便的耕地最大污染负荷量进行估算,得出畜禽养殖污染负荷警报值。结果表明:武汉城市圈农田畜禽粪便猪粪当量平均负荷量为35.48 t/hm2,农田畜禽粪便污染负荷平均警报值为0.79,这一水平值远高于全国警报值0.49;武汉城市圈除仙桃市外,其余各市的畜禽粪便排放均对环境构成威胁,其中,黄冈市畜禽养殖对环境构成较严重威胁,其次是孝感市。Wuhan metropolitan area which is the national ＂resource saving＂ and ＂environment friendly＂ experimental zone was chosen as the study area.On the basis of the amount of livestock,livestock emissions and the area of cultivated land,the maximum livestock pollution load and the alarm value were calculated.The results showed that： the average manure load of Wuhan metropolitan area was 35.48 t/hm2 and the average alarming value was 0.79,which was much higher than the national alarm value 0.49.Except of Xiantao City,the release of manture of animals in other areas of Wuhan had posed threats to the environment.Livestock in Huanggang city posed most serious threats to the environment,followed by Xiaogan city.
