| 估算并分析了2012 年湖北省各地区的畜禽粪便资源总量及分布，在此基础上，结合各地耕地面
积、限量标准对畜禽粪便单位耕地承载量、氮磷负荷对环境的影响进行评价。结果表明：2012 年湖北省畜禽粪
便量达9 870 万t，其中猪粪和牛粪比重最高，占总量的80%。黄冈市、襄阳市的畜禽粪便产量居全省之首，均
超过1 500 万t；而神农架林区的畜禽粪便产量远低于其他地区，仅为11.6 万t。除耕地平均单位面积总磷负
荷为34.03 kg/hm2、略低于35 kg/hm2 的限量标准外，耕地平均单位面积猪粪当量和总氮负荷均高于限量标准，
分别达54.19 t/hm2 和219.12 kg/hm2，其中全省分别有53% 和80% 的地区超过45 t/hm2 和170 kg/hm2 的限量标
准。可见，湖北省畜禽粪便的分布具有地区差异和种类差异，应按地区和畜禽种类不同进行重点控制管理；畜
禽粪便耕地负荷在空间上分布极不平衡，主要集中在黄冈、鄂州、孝感、恩施自治州、襄阳、十堰、神农架林
区、咸宁、武汉等地。 |

| ：This paper estimated and analyzed the resource amount and distribution of animal manure in Hubei
province in 2012，and combined the evaluation standard of cultivated land area，around the unit cultivated land of
animal manure bearing capacity，to evaluate the environmental impact of nitrogen and phosphorus load. The results
showed that 98.7 million t of animal manure were produced in Hubei province in 2012. Among them，pig manure and
cow dung are took up the highest proportion，accounting for 80% of the total，while the rabbit donkeys，horses dung
output were less than 1% of the total. Huanggang，Xiangyang produced the most manure，more than 15 million t；
While Shennongjia had much lower than other areas，only about 116 000 t. The average total phosphorus load per unit
area of cultivated land was 34.03 kg/hm2，which was slightly lower than the standard of set limit（35 kg/hm2），per
unit cultivated land area of pig equivalent evaluation standard and total nitrogen load were 54.19 t/hm2 and 219.12 kg/
hm2 respectively，and 53% and 80% areas of the province had more than 45 t/hm2 and 170 kg/hm2. In Huanggang，
Ezhou，Shiyan，Xiangyang，Xiaogan，Enshi，Shennongjia and Wuhan，pig equivalent load was over limited standard.
Areas where nitrogen load exceeded the limit standard were Wuhan，Huangshi，Shiyan，Yichang，Xiangyang，
Ezhou，Jingmen，Xiaogan，Huanggang，Xianning，Enshi，Qianjiang，Shennongjia. Areas where phosphorus load
exceeded standard were Shiyan，Xiangyang，Ezhou，Xiaogan，Huanggang，so we must take measures depending on
the kinds and regions. It can be concluded that livestock and Poultry manure of cultivated land distribution was highly
uneven on the space，mainly concentrated in Huanggang，Ezhou，Xiaogan，Enshi，Xiangyang，Shiyan，Shennongjia
and Wuhan. |
