摘要: 以县级行政区为研究单元,建构了5类集成性指标项和由"主导影响因素的单要素整体分析—可量化主导因素的基于ArcGIS层次聚类分析法—瓶颈因素限制法"构成的技术路线,测度以云南为代表的山区省份县域综合发展潜力的空间分异特征。结果表明:①云南省县域综合发展潜力差异性显著,且存在很强的空间集聚特征;②总体空间分异呈现城市群高而周边低,交通干线廊道高而影响区低格局,而滇中城市群已形成中心—边缘格局,滇东南、滇西、滇南等城镇密集区初现点状格局;③总体空间分异与交通条件、经济基础呈高度空间正相关。

Abstract: The regional comprehensive development potential (RCDP) zoning at province level is a key foundation of major function oriented regionalization. This article made an assessment on the spatial difference of counties in the mountainous provinces like Yunnan Province. Five Integrated Development Potentials’index item (IDPII) have been constructed by means of theoretical analysis, factor analysis,GIS spatial analysis via ArcGIS9.0 and Geo DA, and expert consultation. It follows a technique route: 1) identifing key factors and spatial analysis; 2) clustering analysis from ArcGIS9.0 for the quantitative index item; 3) spatial bottleneck factors analysis with Cannikin Law by ArcGIS9.0; and 4) integrated appraisal. The results showed that: 1) There are great differences among the counties in RCDP at county level. And the spatial concentration and spatial correlation are distinctive in Yunnan Province. 2) The general spatial differences are formed. First, the cities were higher than rural areas around. The main traffic lines, and the cities and towns nearby are higher than the other areas. Second, the cities agglomeration in the central Yunnan Province is outstanding from other parts. The center of this part is Kunming City. The expansion of the core (Kunming) to the periphery is like quadratic damping from the core. The central Yunnan Province has formed the Core-Periphery structure. The cities in southeastern, southern and western Yunnan Province are just scattered in broad areas, not agglomeration. 3) The spatial differences of Yunnan Province are highly correlated to transportation accessibility and foundations of local economy at county level.
