摘要
随着城市快速发展,城市用地面积与内部结构因其功能的改变与完善也在加速演变,城市在空间上的扩展及内部结构的演变与优化成为当前关注的热点。本文以吉林省2006—2017年城市用地为研究对象,采用土地利用动态度、土地利用结构信息熵与均衡度,依托ArcGIS空间分析功能分析了城市用地质心,进而对吉林省城市用地时空演变进行了分析。结果显示:吉林省城市用地总体呈缓慢增长趋势;2006—2011年信息熵值稳定在1.85,均衡度在0.85左右,2012—2017年有小幅下降,信息熵在1.78左右,均衡度为0.86,说明吉林省土地利用类型结构逐渐趋于稳定,均质度不断提升;城市用地质心总体向西北方向变动,移动距离约为10.74公里。
With the rapid development of the city,the urban land area and internal structure are also accelerating due to the change and improvement of its function,the expansion of urban space and the evolution and optimization of its internal structure have become the focus of attention.This paper takes Jilin Province as an example from 2006 to 2017,urban land is taken as the research object,and land use dynamic degree,information entropy and equilibrium degree of land use structure are adopted,based on the spatial analysis function of ArcGIS,this paper analyzes the urban geological center,and then divides the spatial-temporal evolution of urban land use in Jilin Province Analysis.The results show that:the overall urban land use in Jilin Province shows a slow growth trend;the information entropy value is stable at 1.85 from 2006 to 2011,the equilibrium degree is about 0.85,information entropy value is a slight decrease from 2012 to 2017,the information entropy is about 1.78,and the equilibrium degree is 0.86.The results show that the structure of land use types tends to be stable gradually,and the evenness is increasing in Jilin Province;the urban geological center is changing to the northwest the moving distance is about 10.74 km.
