充分发挥不同地域单元交通优势和规避交通劣势等建议与对策,为地区经济发展战略制定、产业选择和空间结构优化奠定基础,为长江三角洲地区发展提供支撑和保障作用

摘要:以长江三角洲地区为研究区域,将其划分为72个基本研究单元,运用GIS分析技术,构建多文指标体系,从公路网络密度、交通干线影响度及区位优势度三个方面分别对研究区域进行分析,并综合分析其交通优势度,探讨长江三角洲地区交通综合优势度的空间分布格局和特征及其形成因素,结果表明:(1)长江三角洲地区公路网络密度位居全国前列,但公路网络密度区域差异明显,北高南低;(2)上海、昆山、太仓、杭州、宁波五个地区为交通干线影响度最优区,沪宁—沪杭—杭甬沿线地区为交通干线影响度优良区,且从该区域起向南、北两方向,其交通干线影响度逐渐变差;(3)区位优势度空间格局呈现明显的中心—外围特征,上海及其临近地区区位优势度最高,区位优势度以上海及其周边地区为中心向四周递减;(4)长江三角洲地区交通综合优势度空间分布格局南北差异较为明显,北部地区总体优于南部,交通优势度最优地区为上海及其毗邻地区,交通优势度良好地区为沪宁沿线、沿江地区以及沪杭沿线,交通优势度较差地区为南北部边缘地区。本文最后提出充分发挥不同地域单元交通优势和规避交通劣势等建议与对策,为地区经济发展战略制定、产业选择和空间结构优化奠定基础,为长江三角洲地区发展提供支撑和保障作用。40251

Analysis of traffic comprehensive advantage based on GIS
—a case study of Yangtze River Delta
Abstract: It takes the Yangtze River Delta as the study area, which can be pided into 72 basic research unit and builds a multidimensional index system, doing an analysis by using the technology of GIS from the density of road network, the effect of the traffic trunk line and the advantage of the location, giving a comprehensive analysis of its traffic advantages, and also discussing the spatial distribution pattern and characteristics of the Yangtze river delta integrated transportation advantage and its forming factors. The results of the research are as follows. (1) The road network density of the Yangtze river delta region ranks among the top, but there is a striking difference from the north to the south in it, high in the north and low in the south (2) The densest is in Shanghai and its neighboring kunshan .Taicang, Hangzhou and Ningbo. The regional comprehensive transportation along the Shanghai-Nanjing, and the Shanghai-Hangzhou, is of great convenience, which is getting worse from the area towards north and south .(3) The spatial pattern of the location advantage takes on the center - periphery characteristics. There is a most highest location advantage in Shanghai and its neighboring areas, which declines from the center to the surrounding (4)The  traffic space distribution pattern of the Yangtze river delta region makes a clear distinction from the north to the south, the north being better than the south. Shanghai and its adjacent areas have an advantage over other regions in transportation. The shanghai-Nanjing and shanghai-Hangzhou expressways, and the region along the Yangtze river in terms of transportation is second to Shanghai and its adjacent areas and the edge of the southern and northern area is poorer. Finally, a suggestion is put forward on how to make full use of different geographical units such as traffic advantages and avoid disadvantages. Suggestions and countermeasures lay a foundation for the regional economic development, industry selection and spatial structure optimization and provide support for the development of the Yangtze river delta region and the safeguard function.
