RIGIONAL DISPARITY AND ENVIRONMENTAL RISK ASSESSMENT OF LIVESTOCK AND POULTRY BREEDING INDUSTRY IN JILIN PROVINCE

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.
