摘要:

从路网密度、可达性和区位优势度3个方面构建区域交通优势度综合评价指标,并采用熵权TOPSIS法对河南省2003年和2008年县域单元的交通优势度进行综合评价;进而运用ESDA法对交通优势度及增长空间格局进行探讨。研究表明,河南各县市交通优势度均获得了不同程度的改善,交通优势度呈现出显著的空间相关性和空间集聚特征,中心与外围间、平原与山区间的交通优势度空间差异显著;高速公路网络的构建使中原城市群地区大多数县市的交通优势度获得了大幅度提升,但豫南和豫西南山区、盆地的相对增长率较高;最后指出,充分利用地区交通优势和规避交通劣势是地区经济发展战略制定、产业选择和空间结构优化需要考虑的基础要素。

Abstract:

In the article, the indicators of transportation superiority degree are established from the aspects of road network density, regional accessibility and location superiority; and the county level transportation superiority degree is evaluated in 2003 and 2008 in Henan province by the entropy weighted technique for order preference by similarity to ideal solution method (TOPSIS) and GIS technology. Then, the spatial pattern of degree and the growth trend of transportation superiority are deeply discussed by utilizing exploratory spatial data analysis method (ESDA) method. Result show that the transportation superiority degree of every county has been enhanced continuously since 2003 and displayed a strong trend of spatial correlation, the similar units cluster in space. The spatial difference is remarkable between core areas and periphery areas, and also between plain areas and mountain areas. The hotspots counties that with better transportation superiority are centralized in the areas along the transportation corridors of Beijing-Guangzhou highway, Beijing-Guangzhou railway in Zhengzhou, Xuchang and Xinxiang. Transportation superiority in many counties in Zhongyuan urban agglomeration zones got great progress following the construction of highway network. But the relative growth rate is higher in the mountain, basin zones in south and southwest Henan than other zones. At last, it is pointed that transport infrastructure is the antecedent condition to enhance regional spatial linkages and to promote location superiority. And also transport infrastructure is the basic condition to guide direction layout of industry, expanding of urban areas, and formation of traffic economic belt, optimization of regional spatial structure and growth of urban agglomeration zones or economic zones. Therefore, leverage the advantage or circuit the disadvantages of transport infrastructure in regional development is the key factor that should be considered in regional development policy planning, industry selection and regional spatial structure optimization.

Key words: transportation superiority, entropy weighted TOPSIS method, spatial pattern, Henan
