摘要
研究目的:基于GIS技术和可拓学评价模型,对长株潭、长三角和珠三角城市群公路交通效率进行比较研究,建立区域性公路交通效率评价指标体系。本文意在通过对三个城市群的公路交通效率评价指标的比较和分析找出长株潭与长三角、珠三角公路交通效率差距;运用可拓学评价模型对长株潭城市群公路交通效率进行评价。研究结论:(1)目前长株潭城市群公路交通效率处在'一般'的层次上;(2)长株潭城市群与长三角、珠三角城市群公路交通效率的差距主要体现在公路路网里程、地均公路路网密度、单位公路路网产出、地均GDP以及客货运量等方面;长株潭城市群公路交通效率在规模以上工业企业综合效益(经济指标)和单位长度公路路网产出(公路路网指标)等方面有着一定或潜在的优势;(3)可拓学评价模型能系统客观的对城市群公路交通效率进行计算和评价,对国内其他城市群公路交通效率评价研究有着一定的参考意义。
Research purposes： The highway traffic efficiency of the three urban agglomerations called Changsha - Zhuzhou -Xiangtan, Yangtze River Delta and Pearl River Delta were evaluated in this paper based on Geographic Information System （GIS） and extension theory evaluation model. An evaluation index system of regional highway traffic efficiency was established. This paper intends to find the highway traffic efficiency gap between Changsha -Zhuzhou - Xiangtan and Yangtze River Delta, Pearl River Delta via comparing and analyzing the highway traffic efficiency evaluation indexes of the three urban agglomerations, and applies extension theory evaluation model to evaluate the highway traffic efficiency of Changsha -Zhuzhou -Xiangtan urban agglomeration. Research conclusions： （ 1 ） The highway traffic efficiency of Changsha - Zhuzhou - Xiangtan is in the normal level at present. （2） The difference of highway traffic efficiency between Changsha - Zhuzhou - Xiangtan and Yangtze River Delta, Pearl River Delta are mainly in aspects of highway network route length, per acre highway network density, unit length highway network output, real GDP per acre, passenger and freight volume etc. The highway traffic efficiency of Changsha - Zhuzhou - Xiangtan has some certain and potential advantages in the aspects of industrial enterprises above designated size comprehensive benefits （economic index） and unit length highway network output （highway network index） etc. （3） The main reason which leads to the difference between Changsha- Zhuzhou -Xiangtan and YangtzeRiver Delta, Pearl River Delta has been analyzed by applying the extension theory evaluation model which could calculate and evaluate the highway traffic efficiency objectively. This paper also provides the valuable reference to evaluate the highway traffic efficiency of other urban agglomerations of the country.
