摘要
改革开放以来,吉林省进入工业化和城市化的快速发展时期,城市布局集群化现象明显。传统的空间分析方法很难深入刻画城镇体系空间格局的时空演变过程。因此,运用Kernel空间密度分析方法,就改革开放以来吉林省城市集聚区的空间演进过程进行系统研究。结果显示:①1986-2007年间,吉林省城市空间分布集中表现为4个城市群组集聚区;②吉林省城市集聚核心区为长、吉两市;③1986-2007年间,吉林省城市空间格局在中东部方向的拓展较为明显,而东部和西部城市空间分布密度变化不明显,其省域空间分布具有"中东部偏密集/东、西部较稀疏"的空间格局特征;④吉林省城市分布空间的节点结构呈现多空间层次的结构特征。
The phenomenon was obvious in urban layout clustering of with the rapid development period of industrialization and urbanization of Jilin Province since the reform and opening in 1978.It was very difficult to describe the temporal and spatial pattern of urban system by traditional spatial analysis.In this paper,we used a new method-Kernel density analysis to research on the evolution of urban agglomeration area in Jilin Province since the reform and opening-up.We can get four conclusions as follows: ① the spatial distribution of Jilin Province has 4 urban agglomerations during the year of 1986 to 2007;② the core areas of urban agglomeration in Jilin Province are the cities of Changchun and Jilin;③ it is more significant for the urban spatial pattern in to expand the direction of middle east in Jilin Province during the year of 1986 to 2007,while the urban spatial density in the east and west of Jilin Province didn't change significantly;④ the nodes in urban spatial distribution of Jilin Province showed the feature of multi-level and multi-space structure.
