Study On The Spatial Correlation Of Urban Land Use System Health Level

The speed of optimization of land function and output of land efficiency cannot match the rapid change of land structure,and the problems about man using land has occurred in China.With the formation of city circle and urban agglomeration,the tremendous benefits and side effects of urban development will also radiate to other neighboring cities.Therefore,based on the status of China's land development,determining urban land use system health can evaluate urban land use status and support the basis for land sustainable development.Through analyzing the spatial association of land use system health in different cities,can we learn more comprehensive and systematic knowledge about China`s land use.It is also important for land use overall planning and overall deployment.According to the existing literature analysis,the research contents of urban land use system health mainly focus on the evaluation of land use in different periods,and the analysis of the space level is rare.We will study the space interaction from resources,society,and economy,based on the land use system health level of theoretical study,and the consequences are valuable.Firstly,the concept model of the space correlation of urban land use system health has been constructed,and the impact factors have been chosen by qualitative analysis method.Then,based on index system,the exploratory spatial data analysis(ESDA)method has used to constitute the spatial correlation model for urban land.Finally,by means of SPSS,Arcgis 10.2 and Geoda software to analyze the data of the nine districts in Chongqing city in 2010 and 2015.The consequences show an upward trend,and the quantity of “critical health” is large.The health level distribution is from “ring radiation” to “polarization”.Some places changed from “L-L” or “L-H” to “H-H”,and the center of “high health” transferred to southern place and the center of “high health” became in the northern place in 2015.It is the reason of polarization and the enhance of global space correlation.Therefore,the government should make appropriate policy measures to ensure the rational use of land resources.
