Coupling Development Of Urbanization Level And Urban Resilience

The coupling of urbanization and urban resilience will provide a more livable and productive living environment for urban residents.The improvement of urbanization level provides more financial support for urban resilience construction,while the improvement of urban resilience can effectively cope with the uncertainties faced in the urbanization process and create a favorable environment for the healthy promotion of urbanization.Over the past 40 years of reform and opening up,China’s economic and social landscape has undergone radical changes,but the rapid growth has also led to problems such as "emphasizing the surface over the interior" and "emphasizing the ground over the underground" in the process of urban construction,resulting in more and more natural and human disasters.The natural and human disasters are becoming more and more prominent.Henan Province is a typical microcosm of China’s economic and social development as it is a large population and economic province in China.Based on vulnerability theory,growth pole theory,sustainable development theory and the mechanism of the relationship between urbanization and urban resilience construction,this paper takes Henan Province as the research area,integrates statistical data for many years,uses CRITIC method and entropy value method to determine the weight of each indicator,and integrates exploratory spatial data analysis,coupled coordination model,spatial Markov chain and gray correlation model to explore The spatial evolution of the coupled development of urbanization and urban resilience in Henan provincial cities from2011 to 2020.Based on the in-depth analysis of the factors affecting the coupling development,Henan Province is divided into three types of urbanization and urban resilience coupling coordination areas: high,medium and low,and the corresponding optimization strategies are proposed.The research results show that:(1)The overall urbanization level is low,with a spatial distribution characteristic of "high in the northwest and low in the southeast".During the study period,the absolute and relative differences of urbanization levels of Henan cities are both fluctuating and decreasing,indicating that the urbanization level of Henan Province is gradually developing from uneven to balanced.In terms of spatial distribution,the spatial pattern distribution of urbanization level is relatively stable,but there are large differences among regions.Among them,the regions with higher urbanization levels are mainly located in central and western Henan,while urbanization in southern Henan,such as Nanyang and Xinyang,has been at a low level.(2)The urban resilience index is generally low,and the maximum value of urban resilience measurement in Henan Province from 2011 to 2020 is only 0.492.In terms of spatial distribution,the clustering distribution of high and low level of urban resilience in Henan Province is obvious,and the evolution of spatial pattern shows three stages of "polarization-dispersion-balance".The evolution of spatial pattern shows three stages of "polarization-dispersion-balance".In the polarization stage,a single core of high level area is formed with Zhengzhou city as the center;in the decentralization stage,the rise of neighboring cities such as Luoyang,Jiaozuo,Xinxiang and Jiyuan gradually evolves;in the equilibrium stage,the cities of each resilience level are relatively evenly distributed in Henan province.(3)The coupling coordination between urbanization level and urban resilience is medium.The coordination level of most cities hovers between barely coordinated and basically coordinated.From the spatial dimension,the coupling coordination degree of the two systems is optimized year by year,and the coupling level gradually shifts from near disorder to primary coordination,and shows the structural characteristics of core polarization and "center-periphery".The Moran index analysis shows that the global autocorrelation of the coupling coordination degree is positive and the correlation of spatial distribution is significant.From the local autocorrelation analysis,it can be seen that the distribution of the hot spots and cold spots of the coupling coordination degree is different,and the spatial characteristics of "high in the northwest and low in the southeast" are obvious.(4)The evolutionary trend of the coupling coordination between the two is steady to good,and the neighboring areas will influence each other.Specifically,cities with lower levels of coupled coordination tend to move to higher level convergence clubs when they are adjacent to higher level cities;while cities with barely coordinated and primary coordination levels will promote their own coordination when they are adjacent to cities with similar levels;cities with higher coordination levels have higher stability,and the probability of changing levels due to the environment of the neighboring areas is extremely small.(5)The evolution of the coupled coordination degree of urbanization level and urban resilience is closely related to the degree of regional modernization,social development environment,transportation capacity,social security system,and government macro-control.The analysis based on the construction of gray correlation model shows that: the level of agricultural modernization has the greatest influence on the coupling coordination degree,which is closely related to the development orientation of Henan Province itself;the ranking of marketization index,road network density and government support ability are in a fluctuating decline;while the ranking of industrial modernization level,urban service level and green living level show a fluctuating upward trend,which is due to people’s pursuit of The reason is people’s pursuit of good living space.
