成都市畜禽养殖环境承载力分析

Analysis of Environmental Carrying Capacity for Livestock and Poultry Breeding of Chengdu

依据2016年成都市畜禽养殖统计数据,文章分析评价了成都市畜禽养殖环境承载力现状。结果表明,2016年成都市耕地畜禽粪便承载力的预警值平均值为0. 378,级别为Ⅰ级,对环境无污染风险,但有8个区市县级别为Ⅱ级,对环境稍有污染。2016年成都市最大畜禽饲养容量为2271. 66万头猪标准动物,剩余饲养容量为1138.80万头猪标准动物。研究结果可为成都市种养业平衡发展提供参考。

Based on the statistical data of livestock and poultry breeding of Chengdu in 2016,the environmental carrying capacity of livestock and poultry breeding was explored. The results showed that in 2016,the average warning value of the carrying capacity of livestock and poultry manure of Chengdu was 0. 378,and it was grade 1,meaning there’s no environmental pollution risk under this situation. But there were also 8 administrative districts were classified as Grade Ⅱ,meaning that the environment was slightly polluted. The largest environmental capacity of livestock of Chengdu was 22. 7166 million pigs( standard animal),and the number of livestock and poultry in 2016 was 0. 1133 million standard pigs,so there were still 1138. 80 million pigs of environmental carrying capacity left.
