中国城市高质量发展与土地利用之间的耦合协调关系演变--基于探索性时空分析的新证据

How does the coupling coordination relationship between high-quality urbanization and land use evolve in China? New evidence based on exploratory spatiotemporal analyses

Urbanization interacts with land use through resource consumption and space en-croachment.Clarifying the spatial correlations of the interactive relationship between urbaniza-tion and land use,along with their spatiotemporal dynamics,is of vital importance for address-ing the complex interplay between urban development and land resources and identifying re-gional differences.However,previous studies have not sufficiently explored these issues.Herein,we introduce a coupling coordination degree(CCD)model and present the results of exploratory spatiotemporal analyses involving in-depth investigation of the CcD between ur-banization quality and land-use intensity in 290 Chinese cities.The results demonstrate that the CcD for most cities was at the transition-period or basic-coordination stage.The dynamics of the spatial correlation of the CCD was found to increase from the east to the central and west-ern regions,but this was found to decline overall.The movement direction and spatial de-pendence of the local spatial structure of the CcD exerted a dominant synergistic effect.The transition of the spatial correlation was mainly Type I(stable local and neighboring morphology),showing strong transfer inertia,path dependence,and locking features.Dynamic transitions occurred more in central and eastern cities.The results suggest that more cross-city coopera-tion could contribute to moderate land-resource exploitation for high-quality urbanization.
