Analysis Of Social And Economic Coordination Of Population Distribution In Qinghai Province

In this paper,based on the ArcGIS,SPSS,Geoda softwares,and the da ta of population in Q inghai Province from 2000 to 2015,this paper,used the methods of population density analysis,Lorenz curve analysis and spatial autocorrelation analysis,to analyze Population distribution spatio-temporal pattern and then quantitatively evaluated the coordination of population distribution and social economy in Q inghai province.From 2000 to 2015,the overall pattern of population distribution in the Q inghai province was: Lorenz curve analysis and standard deviation ellipse analysis shows that,in recent 15 years,the distribution pattern of population spatial in province was basically stable,but the phenomenon that the spatial distribution was not balanced obviously and the concentration of the population was not significant enough.There is a decreasing trend in the northeast-southwest and northwest-southeast directions.However,the distribution of the population distribution on the two axes is basically stable.The trend analysis,intuitive description of the 16 years,the distribution pattern of the whole province was basically stable in the north-south direction and the east-west direction.From 2000 to 2015,the demographic distribution of the province was characterized by increasing the population density of the whole co unty.The population density of the whole county was increasing in 16 years.The population pattern of the province was basically stable.The high density and high growth area was mainly in the eastern region of Q inghai Province.The medium density area in the Qinghai Lake area and the main source of the Sanjiangyuan area,low density and relatively small increase in the region to Qaidam and the Three Rivers source area mainly in the western region.Spatial autocorrelation analysis shows that the population density in Q inghai Province had a positive auto-correlation,but the spatial auto-correlation of population density in the county was decreasing.High agglomeration zone was mainly for Xining city and its radiation area of Pingan region,Datong county,Huangzhong county.This low-low concentration area mainly for the western part of the Sanjiangyuan area and most of the county(city),was not significant,mainly concentrated in the southern part of the eastern region,the Q inghai Lake area and the eastern part of the Sanjiangyuan area.The analysis of the geographical concentration Population shows that the population of the whole province was not very homogeneous and the distribution was very uneven.And center of Xining was expanded to the west.The analysis of the influencing factors of population distribution in Qinghai Province based on geography weighted regression shows that the AICc,R2 and R2 Adjusted of the GWR model and the OLS model show that the fitting effect of the GWR model is better than the OLS model,and the fitting effect of the GWR model To the east constantly enhanced.The economic factors(GDP)had a positive correlation with the population density,and the regression coefficient from east to west was decreasing.The number of beds in the county had Population density was positively correlated,the regression coefficient gradually decreased from east to west.Population of economic gravity analysis shows that in Qinghai Province’s population distribution center and economic center of gravity were located in the geometric center of the northeast direction,show that the distribution of the population and economy deviates from the direction was consistent,but the center of gravity of deviation degree of distribution center of gravity of deviation degree more than economics.From 2000 to 2015,distribution center and economic center of gravity of the Q inghai population deviation distance increases after the first decreases,and change in small,although population center of gravity and ce nter of economic gravity had offset phenomenon,but there was a coupling relationship between the general trend.The population distribution and socio-economic coordination evaluation show that the population distribution and socio-economic coordination in Q inghai Province show that the eastern part was better than the west and the north was better than the basic pattern of the south.The eastern part of Q inghai Province was mainly coordinated with moderate coordination and moderate coordination.The Qaidam area was mainly coordinated with high coordination and the type of coordination was changing.The Q inghai area was mainly coordinated with high degree of coordination.Some areas of the main and eastern regions were moderately or highly coordinated.The highly coordinated areas were mainly distributed in the provincial capital and municipalities,such as Xining city,Gonghe county and Maqin county.The coordination type of the agricultural counties in the Sanjiangyuan area and the eastern region in the low coordination area was mainly affected by economic factors.
