厦门市城市空间发展的分维变化特征分析OA

Based on fractal theory,the radius dimension is used to research the fractal dimensional change of urban spatial development in Xiamen City during 2004-2021,to explore the evolution characteristics of Xiamen's urban spatial morphology,and the reasons are analyzed in combination with the actual development situation.Through the method of calculating the radius dimension,the spatial morphology analysis characteristics of key functional land use types are investigated.The results show that under the area radius definition,construction land in Xiamen City shows a distribution characteristic of first dispersing and then aggregating.The distribu-tion characteristics of industrial land and residential land are consistent with those of the citywide construction land,while the commercial land shows a distribution characteristic of first dispersing and then stabilizing.The agglomeration degree of Xiamen's urban space is mainly affected by natural conditions and planning policies.
