Evaluation and early warning of environmental carrying capacity of regional livestock and poultry breeding

Based on the perspective of industrial ecological economic system and from the perspective of economy, society and nature, the development and restriction indexes were selected to construct the evaluation index system of regional livestock and poultry breeding environmental carrying capacity. The system analysis model was used to measure the environmental carrying capacity of livestock and poultry breeding in various regions of Jilin Province from 2010 to 2019, and the grey prediction model GM(1,1) was used to predict the environmental carrying capacity of livestock and poultry breeding in various regions of Jilin Province from 2020 to 2029. The results showed that under natural conditions, the overall environmental carrying capacity of livestock and poultry breeding in the next 10 years is not optimistic. Among the nine administrative regions, Jilin, Siping, Tonghua, Baicheng and Songyuan would become weak areas of livestock and poultry breeding environmental system carrying capacity, and the environmental pressure of livestock and poultry industry gradually increased. It was suggested to reduce the number and scale of breeding, carry out industrial transfer and ecological restoration as soon as possible, and consider taking the road of ecological industrialization. Yanbian, Changchun, Baishan and other three regions will become optimistic areas of environmental carrying capacity of livestock and poultry and Liaoyuan area will be more optimistic areas of livestock and poultry breeding environmental carrying capacity. It suggested to maintain the existing livestock and poultry breeding mode, strengthen the ecological environment protection, and moderately carry out sustainable livestock and poultry industry development activities. The development of regional livestock and poultry breeding industry must explore the path of coupling, coordination and sustainable development under the constraints of environmental system carrying capacity.
