摘要
构建加权地形修正系数的交通优势度模型,对河南省126个县市的交通优势度进行测算。在县域交通优势度和经济发展水平评价的基础上,采用耦合协调度模型分析交通优势度和经济发展的作用关系。结果表明:(1)河南省交通优势度呈现从中心向外围逐渐递减的类圈层结构,经济发展水平整体较低,大体表现为从西北到东南逐渐递减的分布特征;(2)河南省交通与经济的耦合协调度呈东高西低、北高南低、中部高边缘低的空间格局,修正后西部山区交通环境被高估的情况有所改善,基于修正后的交通优势度模型与经济发展的耦合结果更为符合客观事实;(3)各县市交通优势度与经济发展的关系以中低度协调耦合型为主,绝大多数县市交通发展超前,交通对经济的正反馈作用尚未充分显现。
Using the revised evaluation model of transportation superiority degree contains transport network density,accessibility,location superiority and natural geographical elements which including elevation,slope,surface,relief and roughness four aspects,the paper evaluated the county level transportation superiority of 126 counties in Henan in 2014.Based on the evaluation of county’s economic development,with the help of the concept of coupling-coordination degree to explain the relationship between the transportation superiority and regional economic development.The main result shows that transportation superiority has significant difference in Henan,transportation superiority reduced gradually from center to periphery,traffic center’s radiation effect is obvious.County level economic development in northwest part of Henan were higher than in southeastern,mountainous resources counties were higher than plain agricultural counties;The counties which are higher than the average value of the coordination degree are mainly concentrated in the areas of middle and northwest of Henan.Central city and counties with high level of economic development generally have higher coordination degree.The mountain areas and border districts have lower coordination degree.Compared with the original model of transportation superiority degree,the revised evaluation model results is more close to the objective facts;Although the coupling degree between transportation superiority and economic development was high,most counties had lower coordination degree;the transportation infrastructure of most counties were ahead of regional economic development,transportation support for the economic development did not give full play to the role.Henan should take full advantage of the existing traffic advantage support to accelerate the development of county economy.
