海南省耕地利用与粮食生产耦合协调发展研究OACSTPCD

The article established a coupling coordination model of cultivated land use and food production in Hainan Province,analyzed the development and mutual influence of cultivated land use and food production during 2010～2021 from the time sequence,and then analyzed the development status of cultivated land use and food production of the 18 municipalities and counties in Hainan Province in 2021 from the spatial point of view.The results showed that:(1)The degree of coordination between arable land use and food production gradually increased from 2010 to 2021,from barely coordinated to basically coordinated and well-coordinated.(2)The degree of coupling and coordination between the two systems continued to increase from 2010 to 2021,and the overall synergistic effect of the arable land use and food production was also increasing,but the development of arable land use and food production were still in a state of incomplete synchronization.(3)In 2021,17 of the 18 cities and counties in Hainan Province,except Qionghai City,are at a high level of coupling between arable land use and food production,and Qionghai City is at a stage of friction between arable land use and food production.In conclusion,Hainan Province should strictly control the amount of arable land,stabilize the sown area for grain,strengthen the quality management of arable land,improve the production capacity of arable land,and strengthen the resilience to natural disasters to reduce the damage.
