吉林省畜禽粪尿总量估算及其环境风险分析

Assessment of the Production of Animal Manure and its Environmental Risk in Jilin Province

利用统计资料和文献数据,结合国内外研究,确定吉林省畜禽粪尿资源的计算参数和计算方法。根据吉林省2011年畜禽饲养量的统计数据估算了吉林省畜禽粪尿产生量、污染物产生量及其流失量。结果表明:2011年吉林省畜禽粪尿总量为7614.99万t,畜禽粪尿污染物产生量910.86万t,污染物流失总量为273.26万t,吉林省畜禽粪尿单位耕地负荷为11.16t/hm2。畜禽粪尿总量集中分布在长春、四平、吉林和松原地区。吉林省畜禽粪尿污染物承载量环境风险大的县域分布在长春、四平、松原和白山地区。

The calculating parameters and method of manure resources was analyzed and determined based on statistical data and literatures in Jilin province. According to the statistical data of Jilin province in 2011,the paper estimated the amount of livestock animal,pollutant generation and loss of pollution in Ji-lin province. The results show that：the livestock and poultry manure was totaled 761.49 million tons, poultry waste was totaled 9.1 million tons, pollutant loss was totaled 2.73 million tons, and poultry ma-nure cropland load unit 11.16 tons/hectar of Jilin province in 2011.The total amount of livestock and poul-try manure mainly distributed in Changchun,Sipping,Jilin and Songyuan area. The land carrying capacity of the county distribution of environmental risks in Changchun,Siping,Songyuan and Baishan region of Ji-lin Province livestock waste pollution.
