摘　　要：以亮子河流域畜禽散养密集区为研究对象,调查了畜禽散养密集区畜禽养殖现状,研究了该区域的畜禽粪便负荷量、畜禽承载力预警值、畜禽养殖最大承载量情况,并在此基础上开展了畜禽散养密集区土地畜禽养殖承载力评价。结果表明:亮子河流域畜禽散养密集区的畜禽养殖以肉鸡、猪和蛋鸡为主,猪当量为59.99万头;不同镇的猪当量由大到小依次为亮中桥镇、大兴镇、老城镇、通江口镇、昌图镇、八宝镇、庆云堡镇、泉头镇。各镇土地畜禽粪便负荷量差异显著,其中负荷量最大的大兴镇为负荷量最小的庆云堡镇的4.60倍。流域畜禽粪便承载力预警值0.21,污染级别为Ⅲ级,已对环境产生影响。畜禽养殖环境容量结果显示,大兴镇、亮中桥镇、老城镇和通江口镇超过畜禽养殖环境容量,对环境已经产生不同程度的污染,特别是大兴镇超标最严重,需对其加强环境管理。The livestock and poultry breeding in intensive free-range of Liangzi River Basin was taken as the research object,and the current situation of livestock and poultry breeding was investigated and analyzed.For evaluating the carrying capacity of livestock and poultry breeding in research area,loading amounts of animal feces,warning value of livestock and poultry breeding carrying capacity and environmental capacity of livestock and poultry breeding were studied.The result showed that the livestock and poultry breeding mainly included broiler,pig and layer in intensive free-range of Liangzi River Basin,and the pig equivalent of livestock was 599.9 thousand.The pig equivalent of livestock was decreased in the order of Liangzhongqiao Town,Daxing Town,Laocheng Town,Tongjiangkou Town,Changtu Town,Babao Town,Qingyunpu Town and Quantou Town.The load of livestock and poultry manure on the land of each town varied significantly.Among them,Daxing Town with the largest load was 4.60 times that of Qingyunbao Town with the smallest load.The early warning value of the livestock and poultry manure carrying capacity in the basin was 0.21,and the pollution level wasⅢ,which had already had an impact on the environment.The results of the environmental capacity of livestock and poultry breeding showed that Daxing Town,Liangzhongqiao Town,Laocheng Town and Tongjiangkou Town exceeded the environmental capacity of livestock and poultry breeding,and they had caused varying degrees of pollution to the environment.Especially in Daxing Town,the over-standard was the most serious,and environmental management needed to be strengthened.
