摘要： 县域综合交通可达性与经济发展水平之间具有密切的联系。在借鉴现有成果基础上,完善了不受分析空间尺度大小影响的综合交通可达性赋值测度法,尤其强调了火车站的节点属性及其等级对可达性的影响。并以此测算湖北省79个县域的综合交通可达性,结合系统聚类分析法揭示其空间差异规律。并应用主成分分析和系统聚类分析法分别测算县域经济发展水平和分析其空间差异现象,采用相关分析和曲线拟合方法揭示县域综合交通可达性与经济发展水平之间的关系,认为两者之间存在具有正相关趋势的非线性关系。同时运用3×3矩阵分析两者的组合类型和湖北省各类型县域分布规律,验证了"综合交通可达性的改善是实现高经济发展水平的充分而非必要条件"的观点,依据空间差异规律,一方面评述了湖北省现行空间发展战略,建议湖北省实施"一主两副三区四带"点轴式空间非均衡发展战略,另一方面提出了促进县域综合交通可达性全面提升的建议。

关键词: 县域, 综合交通可达性, 经济发展水平, 空间差异, 点轴式发展

Abstract: There is close relationship between the comprehensive transport accessibility(CTA) and the level of economic development(LED) at county level.The article uses some statistical analysis methods to analyze their relationship.Firstly,it modifies the valuation method to calculate the CTA which is not influenced by the analysis spatial scale based on the current research results.Especially,the railway station is regarded as an important transport node and its level has very important influence on the accessibility in the new method.Secondly,it evaluates the CTA of 79 counties in Hubei Province with this method.And it analyzes the spatial difference of the CTA in this province based on the result of systems cluster analysis.Thirdly,it evaluates the level of county economic development and its spatial difference with the method of principal component analysis and system cluster analysis.Fourthly,the non-liner statistical correlation between the CTA with the LED at county level is revealed by the method of correlation analysis and curve fit analysis.Fifthly,this paper analyzes the combination type of CTA and LED with the 3×3 matrix,and the spatial distribution rule of different types of counties as well.Finally,it is suggested that we should choose the imbalanced spatial development strategy,such as pole-axis development.And this article builds a spatial development mode which is "one main center city,two associate center cities,three city-and-town concentrated areas and four economic zones".In addition,it put forwards some suggestions for upgrading the county CTA in Hubei Province.

Key words: county, comprehensive transport accessibility(CTA), level of economic development(LED), spatial difference, pole-axis development
