摘　　要：利用吉林省"十二五"环境统计数据,通过计算畜禽单元密度、耕地总氮(磷)负荷、耕地猪氮(磷)密度、耕地总氮(磷)污染风险等指标,分析了吉林省畜禽养殖量区域差异,并评价其环境风险。结果表明:1)吉林省各地区畜禽养殖量呈现出中部地区较多,西部地区次之,而东部及东南部地区最少的分布特点;2)研究区畜禽养殖总氮(磷)产生量分别为23. 18万,26. 07万t,其中,图门地区总氮(磷)产生量均最低,而位于中部的长春、农安地区总磷产生量最高;3)各地区耕地总氮污染总体上较轻,只存在无污染、低污染和中污染现象,而总磷污染较严重,较高和高风险所占比重较高,其研究结果可为吉林省畜禽养殖业布局调整、环境污染治理和畜禽粪便资源化利用等决策提供支持。Based on the environmental statistical data of "12th Five Year Plan"in Jilin province,this study analyzed the regional disparity of livestock and poultry breeding in Jilin province and evaluated the environmental risk by means of unit density of livestock and poultry,total nitrogen (phosphorus) load and pig nitrogen (phosphorus) density,and total nitrogen (phosphorus) pollution risk of cultivated land. The results showed that: 1) there were more livestock and poultry cultivation in the central region of Jilin province,followed by the western region,while the eastern and southeast regions had the least distribution characteristics;2) the total nitrogen (phosphorus) production of livestock and poultry cultivation in the study area were 231800,260700 t respectively,among which the total nitrogen (phosphorus) production in Tumen was the lowest,while that in Changchun and Nongan region in the central region was the highest;3) total nitrogen pollution of cultivated land in all regions was relatively light,just in rank of no pollution,low pollution and medium pollution,while the total phosphorus pollution was relatively more serious,with a higher proportion of sub-high risk and high risk. The research results could provide support for the decision-making of the layout adjustment of livestock and poultry breeding industry,environmental pollution control and utilization of livestock and poultry manure resources in Jilin.
