山东家禽产业经济与生态环境耦合协调研究OA北大核心CSTPCD

By comprehensively evaluating the economic and ecological systems of the poultry industry in Shandong Province from 2012 to 2020 using an integrated assessment model,this study analyzed the cou-pling coordination relationship between the two systems using a coupling coordination degree model.The results show that:① the comprehensive development level of the poultry industry's economy and ecologi-cal environment is on the rise,with a good development trend.The rapid development of the poultry in-dustry from 2017 to 2020,continuous expansion of breeding scale,and many shortcomings in waste treat-ment during breeding have brought serious adverse effects on the ecological environment,resulting in a re-verse dynamic relationship between the ecological environment and the poultry industry economy.② The intensity of interaction between the economic system of the poultry industry and the ecological environ-ment system from 2012 to 2020 is very high,with coupling degrees both above 0.9.③ The coupling coor-dination degree of the two systems from 2015 to 2020 is on the rise,gradually advancing towards coordina-ted development;however,the coupling coordination degree of the two systems is not high,and in 2020,the two systems are still on the verge of imbalance.In conclusion,while focusing on the development of the poultry industry,attention must also be paid to the protection of the ecological environment to pro-mote the high-quality development of the poultry industry.
