Study on Urban System Spatial Structure and Attractive Scope by Voronoi way:A Case of Guangdong Province
-
摘要: 城市体系空间结构是城镇化的基本载体，构建科学合理的城市体系空间结构是推进新型城镇化的重要内容. 为准确把握广东省的城市体系空间结构特征，使用Voronoi图空间组织方法和加权Voronoi图空间分割方法，以城市综合实力为质量属性，统合考察城市的地理区位和空间关系，对广东省县级以上城市的城市体系空间结构及吸引范围进行研究，得出以下结论：（1）广东省城市发展空间极化现象明显，城市综合发展水平存在较大差距;（2）在城市体系空间结构上，广东省形成了全域性中心城市区域性中心城市地方性中心城市一般性城市4个层级的城市体系空间结构;（3）从城市吸引范围分析，广东省部分城市存在同城化发展现象，其中广佛和潮汕同城趋势明显;（4）广东省城市的综合实力与其空间结构等级间存在明显的错位现象，因此应该进一步明确实力强等级低的城市的区域定位和职能定位，同时加快综合实力较弱的中心城市的发展，缩小发展差距，实现区域协调.

Abstract: Urban system spatial structure is the basic carrier of urbanization, and the construction of scientific and reasonable urban system space structure is an important part of promoting new urbanization. To study the urban system spatial structure and scope of Guangdong Province, the methods of comprehensive evaluation with several indexes, spatial organization with voronoi and weighted voronoi diagram are used. The conclusions are drawn as follows: firstly, the polarization of cities in Guangdong province is obvious, and there is a big gap of urban comprehensive strength. Secondly, it is formed four levels of the spatial structure of urban systems, including global center city, regional center city, local center city and general city. Thirdly, the phenomenon of urban agglomeration integration exists among cities, especially the Guangzhou and Foshan, Shantou and Chaozhou. Lastly, there is an obvious dislocation between the comprehensive strength of Guangdong province and its spatial structure level. Therefore, it should ensure the strength of the low level of the cities regional positioning and functional orientation. At the same time, it should accelerate the development of the central city of weak comprehensive strength, narrow the development gap and achieve regional coordination.-
