Coupling interaction and driving factors of cultivated land use transition and county urbanization:A case study in Henan province
There is a complex interaction and coupling process between cultivated land use transition and county urbanization.It is of great significance to conduct the coupling research of cultivated land use transition and county urbanization for the steady progress of sustainable utilization of cultivated land and high-quality development of urbanization.On the basis of clarifying the coupling mechanism between cultivated land use transition and county urbanization,this study takes Henan province as a case study area to explore the coupling interaction and its driving factors by applying methods such as the coupling coordination degree model and the PVAR model.The results are as follows:(1)From 2000 to 2020,the cultivated land use transition undergoes an evolutionary process,first decreasing and then increasing,with an increasingly balanced spatial distribution.(2)The level of county urbanization is rising gradually,and shows a spatial development pattern of"large agglomeration and small dispersion".(3)The coupling relationship between cultivated land use transition and county urbanization has gradually improved,showing an increasingly balanced spatial evolution trend.However,the coupling coordination degree between cultivated land use transition and county urbanization needs to be further improved.(4)The coupling interaction of cultivated land use transition and county urbanization is influenced by natural,economic,social and governmental factors.The degree of contribution of different factors to the degree of coupling coordination is different,and the degree of contribution of industrial agglomeration,altitude,public financial expenditure and population density is relatively high.The impacts of different factors vary considerably.Industrial agglomeration and public financial expenditure have significant positive effects on the degree of coupling coordination,while altitude and population density have significant negative effects.
