Study On Spatial Heterogeneity And Driving Forces Of Residential Land Price In Main Urban Area Of Chongqing City

The spatial layout of urban residential land is the result of multiple factors.With the adjustment of urban strategic positioning,functional scale expansion,public infrastructure improvement and scheduling optimization,residential land layout structure and scope of a certain evolution.To explore and capture its leading factorsinformation,it is useful to reveal the spatial distribution of residential land and its formation mechanism,and provide decision-making basis for rational planning of urban spatial structure,optimization of traffic infrastructure.In the urban residential land space layout,the city residential land price is not "balanced" distribution,showing a clear regional,structural characteristics.In order to explore its spatial distribution in the urban residential layout,the mechanism of the impact factors on residential land price is analyzed.This papers uses the data of residential land in the main urban area of Chongqing from 2010 to 2015,and studies the spatial layout structure and land price driving force of residential land.In the Research of the spatial structure of residential land,the previous studies on the structure of urban spatial layout are mostly based on the division of the capacity of urban land bidders,which is defined by the spatial dimension Division.Based on the theory of Bid Rent,this paper uses the time reachability instead of the spatial distance,divides the time reachability circle,defines the spatial layout of urban residential space with the time dimension.Analysis of the current traffic operation capacity,the distribution of residential land at all times and the maximum area of residential land transfer,clear residents of housing consumption commute preferences and patience time.In terms of land price driving force analysis,Based on the results of the study on the spatial layout of residential land in this paper,this paper first analyzes the residential data of all the residential data sold in the main city of Chongqing in 2010-2015,The years of use,the volume rate,the degree of development correction and abnormal point exclusion.Then the exploratory spatial analysis(ESDA)is used to verify the spatial correlation and correlation degree of land samples.Finally,the semi-variance analysis of the Geostatisties method and the Kriging space interpolation method are used to analyze the spatial changes of the residential land price,proving the spatial non-stationility of the residential land price.Considering the non-stationility of residential land price in the study area,this papers adopts the GWR.In addition,based on the regional characteristics of the mountainous terrain in the main urban area of Chongqing,this paper chooses the time cost as the measure,which is different from the Euclidean distance of similar research,and tries to reach the actual travel situation in the study area.Research on the Spatial Layout of Residential Land in the Process of Empirical Study.Based on the network analysis and distance cost weighting method of vector-grid data,the traffic volume of public transport and road is set,and the traffic velocity of the barrier zone is set up.The data of residential land transfer in 2010-2015 area and the time-range are calculated.The Research indicates that:(1)In the past six years,the range of residential land transfer has reached the maximum range of 105 min,which is distributed in the range of 60 min.Combined with the study area residential farthest transfer space layout,indicating that the existing traffic operation capacity conditions,the residents of housing consumption commuter patience time is about 105 minutes.(2)As for a single Isochronous line,rail traffic in 15 min and 60 min reachability range significantly.In the local area of equatorial time,it is affected by road traffic capacity,mountain slope and road density.(3)The spatial structure of urban residential land divided by 15-105 min in time(15min interval)shows the decay trend of the center gradually decreasing to the periphery,and the residential land price shows a significant structure in the same time difference.In order to further study the spatial heterogeneity and its driving force factors in the spatial distribution of residential land,this papers chooses six factors such as policy planning regulation,transportation,Business district,education and public facilities and river view resources,and uses GWR model to measure Analysis,The results show that Planning policy factors in the urban development of new areas and the old city significant difference.The park wetland and the square of the gymnasium have a similar effect on a certain spatial extent.The park has a positive effect on the residential land price.The spatial distribution density of schools,hospitals,main roads and rail transit,and interregional traffic reach are closely related to land prices.The richness of the riverview and the terrain slope play a leading role in the residential land price.In addition,in order to refine the differences in the spatial distribution of the influence factors,Screeningthe dominant factors in the spatial and temporal layout,the reachability ranges of 15 min,30 min,45 min and 75 min were selected.Based on the view of the spatial availability of urban residential land,this paper can provide a new direction for the government to plan and arrange the traffic infrastructure.Through the scientific and rational layout of public transport facilities,effectively expands and extends the scope of the city center radiation range,expands the radius of residential space layout for large cities and large cities to provide urban city integration model.Furthermore,it is possible to provide a new idea for the government to formulate the land price of the state-owned land and evaluate the land evaluation of the evaluation institution,and avoid the "average" mode of thinking such as the market comparison method and the benchmark land price method,Seek to maximize the "estimate" of land value.In addition,the use of time accessibility to measure the spatial layout of residential land and influencing factors can provide new ideas for the government to provide public infrastructure and promote equalization of public services.
