The Spatial Configuration of Transport Superiority in Huang-Huai-Hai Plain
运用GIS空间分析和统计功能，研究黄淮海平原的道路密度、交通设施邻近度、可达性和交通优势度，发现该区域交通优势度呈偏正态分布，多数地区处于一般或较低水平，而北京、天津及周边地区优势突出，并形成三条辐射带。
Transport superiority evaluation model presented by Jin Fengjun is a useful tool for assessing the level of regional transport infrastructure.Using spatial analysis and statistics function of GIS,this paper studies road density,transport infrastructure proximity,accessibility and transport superiority of Huang-Huai-Hai Plain.This paper validates that transport superiority in Huang-Huai-Hai Plain presents skewed normal distribution and most areas with normal or low superiority.Beijing,Tianjin and their surrounding areas have superior transport superiority as well as three transport superiority belts radiating from capital area.
