【摘要】：公共服务设施用地是城市功能用地的主要组成部分,公共服务设施用地的集聚与扩散可以更直接地揭示城市空间结构与城市中心地的演变特征。本文以长春市中心城区为研究范围,利用城市用地现状图、地形图等数据资源,借助GIS软件,采用核密度、斑块聚合度指数等方法,分析了长春市2003-2013年公共服务设施用地演变特征与机制。研究发现:公共服务设施用地规模增速低于城市建成区的增速;公共服务设施用地演变特征的圈层差异明显;公共服务设施用地空间结构从"单一化核心+多次级中心"到"多样化核心+多次级中心",空间格局从"大分散、小集中"到"大集中、小分散";城市不同公共服务设施用地类型表现出不同的演变特征;城市公共服务设施用地演变机制为城市功能空间的整体提升、城市功能空间的互动耦合、土地利用的市场竞争、交通设施与网络的完善、城市规划的引导与调控、城市大事件的快速推动。
[Abstract]:Land use for public service facilities is the main component of urban functional land. The agglomeration and diffusion of land for public service facilities can more directly reveal the evolvement characteristics of urban spatial structure and urban central areas. In this paper, taking the city center of Changchun as the research scope, using the data resources such as urban land status map and topographic map, using GIS software, adopting the methods of nuclear density, patch aggregation index, etc. This paper analyzes the characteristics and mechanism of land use evolution of public service facilities in Changchun from 2003 to 2013. The results show that the growth rate of land use for public service facilities is lower than that for urban built-up areas, and there are obvious differences in the changing characteristics of land use for public services facilities. The spatial structure of public service facilities has changed from "single core multi-level center" to "diversified core multi-level center", and the spatial pattern has changed from "large dispersion, small concentration" to "large concentration". Small dispersion "; different urban public service facilities land types show different evolution characteristics; urban public service facilities land evolution mechanism for the overall promotion of urban functional space, urban functional space interactive coupling, The market competition of land use, the perfection of transportation facilities and network, the guidance and regulation of urban planning, and the rapid promotion of major urban events.
