| 摘 要： | 基于兰州—西宁城镇密集区2000-2008年的县域经济发展数据,以县域为研究单元,采用因子分析和GIS技术相结合的方法,对密集区经济差异的空间格局进行综合分析。结果表明:兰州—西宁城镇密集区发展较好的县域集中于湟水谷地、兰—青铁路沿线一带;密集区经济空间格局呈核心—外围空间结构,遵循空间距离衰减规律,且具有东西分异、南北分异和低值集聚、高值分散特征;2000—2008年,兰州—西宁城镇密集区县域经济差异有所减小,其中兰州市区、红古区、白银区和西宁市区保持区域经济核心地位不变,中等水平县域由数量少、斑块状的分散布局转变为范围广、集聚性强的面状空间形态,低增长型县域呈组团式集聚分布于密集区南部。

| Abstract: | Based on the economic development statistics of 35 counties in the Urban Compact Area of Lanzhou-Xining,the paper evaluates the county economic discrepancy by SPSS and GIS.According to the economic level scores,the 35 counties are divided into four main categories.Then we analyses the spatial structure of county economic level and its evolution trend from 2000 to 2008.Conclusions as follows: since 2000,the economic disparities of county level have decreased,the economic developed counties are distributed al... |
