| Taking 441 counties(districts)in the Yellow River Basin as the research object,this paper analyzes the evolution characteristics of the harmonious relationship between population and economic growth in the Yellow River Basin by using the elasticity coefficient of population-economic growth.The spatial agglomeration and coordination of population and economy in the Yellow River Basin were analyzed by gravity center analysis,geographical linkage rate and population and economic discordency index.pearson correlation analysis and exploratory spatial data analysis were used to explore the quantitative and spatial correlation between population agglomeration and economic agglomeration in the Yellow River Basin.The coupled coordination model was constructed to study the coupled coordination of population and economy in the main functional areas of the Yellow River Basin.Based on the GWR model,the spatial differentiation of different factors on the consistency of population and economic agglomeration in the Yellow River Basin was analyzed.The evolution characteristics of spatial coordination between population and economy in the Yellow River Basin in 2000,2010 and 2020 were analyzed.The results showed that:(1)The population growth rate in the Yellow River Basin varies greatly among regions.Since 2010,the population in the upper and lower reaches of the Yellow River basin has increased rapidly while the population in the middle reaches has contracted seriously,and the economic development of the basin has slowed down,especially in the northern part of the basin in 2010.The driving effect of economic growth on population growth in the upper and lower reaches of the Yellow River Basin is increasing,and the most incongrable areas requiring large population increase for economic growth in the basin are decreasing,while the coordinating areas that economic growth can bring moderate population growth are increasing significantly in the Loess Plateau.(2)The distribution of population spatial agglomeration and economic spatial agglomeration is roughly the same,showing the characteristics of high in the southeast and low in the central and western regions.Population center of gravity to the east,economic center of gravity to the west.The distribution of population and economy is more unbalanced,and the matching degree of population and economy spatial agglomeration gradually increases from upstream to downstream.The Yellow River Basin is dominated by the type area where population is ahead of economic agglomeration,followed by the coordination area where population and economic agglomeration are more matched.Although the growth of the coordination area has been obvious since 2010,the disharmony of population and economy has not changed fundamentally.(3)The distance between the center of gravity of population and the center of gravity of economy shrinks gradually,moving in opposite directions.The two are getting closer to each other,and the spatial correlation is enhanced.The spatial agglomeration of population and economy is increasingly related in quantity and independent in space.In recent years,the correlation between low population and low economic agglomeration in the Loess Plateau on the east and west sides of the Hu Line has gradually broken down.(4)From 2000 to 2010,the number of regions with the strongest interaction between population and economic agglomeration increased significantly.The interaction between population and economic agglomeration is stronger in key development zones,agricultural production areas and key ecological functional areas.In 2020,the major development zones and major agricultural production areas will mainly suffer from severe disordered decline,while the major ecological functional areas will suffer from extremely disordered decline and severe disordered decline.The population and economic development level in the Yellow River Basin are out of harmony,at the disordered decline level,and the areas with extreme disordered decline will increase.(5)There is no obvious spatial heterogeneity in the effects of the proportion of the output value of the secondary industry,the balance of the general budget and the per capita savings deposit balance of urban and rural residents on the population and economic coordination.In 2000,the density of river network,the proportion of the output value of the tertiary industry,the number of medical beds per 10,000 people,and the proportion of the number of ordinary middle school students had certain spatial heterogeneity.On the whole,the distribution characteristics in 2000 were more different than that in 2020.Except for the proportion of the output value of the secondary and tertiary industries,the change trend of the influence degree of other factors generally showed a trend of strengthening from east to west,and the influence of the proportion of the output value of the tertiary industry on the coordination of the spatial distribution of population and economy was more complex. |
