摘　　要：我国对畜禽养殖的污染治理非常重视,基于土地、水资源、大气等方面的生态环境承载力评估是确定畜禽养殖业发展布局的关键,目前面向小尺度畜禽养殖区的生态环境承载力分析方法和案例研究还不多见。建立乡镇尺度畜禽养殖潜力评价与生态环境承载力分析方法,以海南省儋州市为例开展研究。结果如下:基于土地承载力、自然生态、畜禽养殖、种植业等4个子系统及其耦合关系构建的畜禽养殖资源环境承载力分析方法,可以有效评价乡镇重点区域的畜禽养殖规模上限;海南省儋州市畜禽粪肥土地承载潜力以氮计约722.66万头猪当量,其中雅星镇的土地承载潜力最高约222.53万头猪当量,可作为全市畜禽养殖重点发展乡镇;儋州市雅星镇畜禽重点养殖区在保证新鲜水资源供给、生产废水“零排放”、配建固相粪便生产有机肥设施等前提下,畜禽养殖规模上限为126万头/年出栏量。China has paid more attention on pollution treatment of livestock breeding.The evaluation of the eco-environment carrying capacity which is based on land,water,and atmosphere was the key to determine the development distribution of livestock breeding.However,there were few methods and case studies for analyzing the eco-environment carrying capacity of small-scale livestock breeding areas.This article established an evaluating method for carrying capacity potential livestock breeding and the ecoenvironment carrying capacity at the town level.The results of a case study of Danzhou City,Hainan Province were as follows.Analysis method for eco-environmental carrying capacity of livestock breeding,which is based on four subsystems and their coupling relationships of land carrying capacity,natural ecology,livestock breeding,and planting industry,could effectively evaluate the upper limit of livestock breeding in the key areas of town level.The carrying potential of livestock breeding in Danzhou city was about 7.2266 million pigs’equivalent for nitrogen,with Yaxing Town having the highest about 2.2253 million pig equivalent which would be main development town for livestock breeding.Under the conditions of adequate freshwater resources,zero discharge of production wastewater,construction of solid manure production organic fertilizer facilities,the upper limit of livestock breeding was 1.26 million pigs’equivalent every year in the main breeding area in Yaxing town.
