武汉城市圈土地资源空间异质性及其效应分析
Spatial heterogeneity of land resources and its effect analysis in Wuhan Urban Agglomeration
摘要
Abstract
The paper built a land resources spatial heterogeneity evaluation model to measure the degree of spatial heterogeneity forland resources of Wuhan Urban Ag glomeration (WUA).Thismodelwascomprised of 12 indicators of land resources (quantity, quality, structure, endowment etc.). Methods of variation coefficient and comprehensive evaluation were employed to calculate weights and heterogeneity index.The relationship between spatialheterogeneity and levelsofeconomic developmentwasexplored aswell. The resultsindicate thatthe variations ofquality and quantity of land resources were the most important factors of spatialheterogeneity.In addition,the heterogeneities of resource endowmentand structure were smaller.R egarding to heterogeneous indicators,economic heterogeneity of land resource was the largest and the heterogeneity of land resource diversification was the smallest. The interval of spatial heterogeneity of land resources in WUAranges from0.226 to 0.590. WUAwas divided into five areas by the heterogeneity index and the heterogeneity index presents a gradient change in various units. In general, the spatial characteristic of agglomeration was “higherin center,lowerin edge”.There was a strong positive correlation between spatialheterogeneity of land resources and the levelof economic development in WUA.Factors including fixed-asset investmentperkm2,GDP Percapita and urbanization rate had positive impacts on land resources spatialheterogeneity in WUA.In contrast,factors including the proportion of secondary and tertiary industrieshad a negative impact.Optimizing the industrial structure and layoutcan reduce spatial heterogeneity.关键词
