Spatio-temporal Pattern and Coupling Coordination of Urban-rural Construction Land in China
Based on the 30 m×30 m resolution land use remote sensing data of China in 2000,2010,and 2020,this study analyzed the spatio-temporal pattern and coupling coordination characteristics of urban-rural con-struction land in China.The bivariate spatial autocorrelation analysis model was used to explore the spatio-temporal correlation and dependence of the spatial distribution characteristics of urban-rural construction land.Concurrently,the coupling coordination and decoupling model was employed to reveal the coordinated development level of urban-rural construction land and the decoupling relationship between them.The findings were revealed as follows:(1)From 2000 to 2020,the area of urban-rural construction land in China continued to increase,with the transfer of cul-tivated land and grassland representing the primary source of this expansion.(2)The level of coordinated develop-ment of urban-rural construction land showed a downward and then upward trend over time,while the distribution pat-tern of high in the northeast and low in the southwest was shown in space.(3)The types of construction land decou-pling were mainly weak decoupling with both urban and rural growth and ahead of the growth rate of urban construc-tion land.Compared to 2000-2010,there were notably more strong negative decoupling and expansionary negative decoupling in 2010-2020,indicating that the development of urban construction land was ahead of rural settlements.
