Comprehensive Evaluation Of Healthy Cities And Research On Coupling Coordination Degree

Urban health is an inevitable requirement for sustainable urban development and high-quality urban development.In recent years,"healthy city construction" has received widespread attention from national and local governments.Although the current regional measurement research has achieved a series of important results in regional economy,ecology,innovation,population,etc.,our systematic understanding of urban health is still insufficient.The level of urban health is affected by multiple factors from inside and outside the city,such as the mutual radiation between cities,the coupling effect between urban subsystems,and the hindering effect of internal factors in the urban system.In order to promote and guide the "healthy city construction",it is urgent to locate the urban health level and explore the relationship between multiple factors inside and outside the city and the urban health level.Based on this,this thesis completes the construction of the evaluation model based on the System Science Theory,Sustainable Development Theory,Coupling Coordination theory,and the entropy weight method.Using the statistical data of 294 cities in China in 2018,using Arc GIS spatial analysis technology,Moran index,coupling coordination model,and obstacle degree model to complete the measurement and analysis of the health level,system coupling coordination level,and obstacle factor obstacle degree of 294 cities,and reached the following conclusions:(1)The health level of cities in China is extremely unbalanced,showing a pyramid shape as a whole,and there are obvious gaps in the health level of cities in the four major regions.Type I and Type II healthy cities accounted for about 8.2%,and Type IV and Type V healthy cities accounted for about 69.7%.The proportion of cities in the eastern region,central region,western region,and northeastern region whose health status is at level III or above is about 47.7%,29.6%,21.3%,and 12.1%,respectively.(2)There is a significant spatial synergy effect in the health level of Chinese cities,and the Northeast region urgently needs to be improved in an all-round way.China’s urban health index,urban ecological health index,and urban economic health index are significantly positively correlated.The Moran index in Northeast China is not significant,which means that the development of cities and their subsystems in Northeast China is relatively disordered.(3)The coupling and coordination level of urban subsystems in China is relatively balanced,and the overall shape is olive-shaped.The coordinated development of urban subsystems is a necessary condition for urban health.Cities with high subsystem imbalance,moderate imbalance,basic coordination,moderate coordination,and high coordination accounted for about 2%,26.5%,49.7%,19.7%,and 2%,respectively.The degree of system coupling is significantly linearly correlated with the level of urban health.(4)The obstacles to urban health level are relatively concentrated,and high-quality economic development is the biggest obstacle to healthy cities.The first six major obstacles hinder the city’s health level by 82.4%,among which the indicators related to economic quality hinder the city’s health level by62.9%.The main innovations of this thesis are:(1)Innovation in the evaluation system of urban health level.This thesis constructs a new urban health index measurement system,which provides a useful reference for future related regional measurement research.(2)Based on the theory of system science,this thesis analyzes the urban health level from the overall spatial analysis of the urban health index(macroscopic)to the degree of system coupling coordination(medium)and then to the diagnosis of obstacle factors(microscopic),providing more information for subsequent related research.method for reference.(3)The problem of urban health level is studied by using an integrated method.
