Spatial And Temporal Evolution Analysis Of Coupling Coordination Between Land Health Use,Economic Growth And Urbanization In Hebei Province

Along with the advancement of urbanization and economic development,increasing demand for land in the human,the contradiction between supply and demand of land has become more prominent,blindly pursue the speed of urbanization and industrialization process,and the health of land use and sustainable utilization,is unfavorable to the improvement of urbanization quality and the healthy development of social economy.County economy is the basic unit of national economy,and the research on the coupling and coordination of healthy land use,economic growth and urbanization in Hebei Province from the perspective of county scale is of great reference value for the promotion of healthy land use,economic and social sustainable development in Hebei Province.To reveal the health of land use and economic growth and urbanization in Hebei province three space-time evolution characteristics of the system,and reveals the healthy land use-economic growth-type coupling coordinated development of urbanization and coordinated development of the space and time structure,based on the existing relevant research results at home and abroad,this study on the health of land use,economic growth,defines the concept of urbanization,and the scientific nature and operability,systemic principle as the instruction,many factors to consider the establishment of index system for each system,Using the comprehensive index method,coupling coordination degree model,spatial autocorrelation analysis on 132 units at the county level in Hebei province from 2002 to 2017 health,land use,economic growth and urbanization evolution of the system,coupling coordination level,temporal and spatial pattern and spatial correlation study,research with the help of ArcGIS software 10.5 and 095 I GeoDa and the calculation results are visual processing,convenient comparison research.The main results and conclusions of the study are as follows:(1)From 2002 to 2017,the comprehensive index of land health utilization system in Hebei province showed an overall upward trend,and the health level of the system was critical in 2017.The comprehensive index of the economic growth system of Hebei province is in a lower level and fluctuated downward trend.Overall,the comprehensive index of urbanization system in Hebei province showed an upward trend of fluctuation.In 2017,the urbanization system level of most counties in Hebei province reached the medium level,and the overall pattern was being optimized.(2)The main type of coupling coordination of county land health utilization--economic growth--urbanization in Hebei Province has changed from mildly maladjusted recession type to near-maladjusted recession type,and the coupling coordination trend is developing towards a better trend.Although the overall coordination level of Hebei Province is improving,the coupling coordination level is still low.(3)There is an internal gap in the coordination level of healthy land use,economic growth and urbanization among all counties and cities in Hebei Province.Compared with other cities,the overall coordination level of Tangshan city is of higher quality in Hebei Province.The heterogeneity of the coordination level of each county and city in Hebei Province is developing towards the direction of coordinated development.(4)There is positive spatial autocorrelation among the three systems of healthy land use,economic growth and urbanization in Hebei Province,and there are high coordination level aggregation area,low coordination level aggregation area and difference area.
