摘要
Abstract
Exploring the characteristics of land use change and the suitability of relative road space allocation in the southwest plateau mountainous area is of great significance to promote the optimal management of land.This paper analyzes the characteristics of land use change in Xuanwei City from 2000 to 2020 from the perspectives of information entropy of land use structure,transfer matrix,dynamic degree,standard deviational ellipse and Moran index,and uses functions of factor detection to analyze the driving factors affecting the spatial distribution of land use.Landmass-road clumping index and landmass-relative road clumping index are proposed to analyze the spatial differentiation characteristics of each land use type relative to road elements.The results show that the efficiency of land use in Xuanwei City has gradually increased.The spatial autocorrelation of various land use types is weak.The center of gravity of construction land has shifted obviously,and the slope,township center and road have the main driving effect on the formation of land use space in the study area.The construction land is closely attached to the road,and the concentration degree is high.The spatial distribution of forest land and grassland is more ideal than that of the road.The aggregation index of cultivated land is low,and the overall distribution pattern of cultivated land relative to the road needs to be further optimized.The methods and results of this study can provide theoretical and application reference for regional land use planning and decision-making.关键词
