摘　　要：笔者在本文中通过量化及案例分析发现,我国干线运输线路大都表现出3/7规律,即大致上看30%的骨干线网承担了全网70%的货物运输量或车公里数,呈现少数关键的设施承担了高比重或核心运输功能的"运输集中"现象。笔者还总结了美欧等国家或地区通道战略规划的经验,基于帕累托改进的思想,提出了我国关键运输廊道识别思路。本文对优化通道资源配置、完善我国综合运输大通道规划建设具有决策参考的理论价值和现实意义。With continuous development of the national transport system in China, a small number of key facilities have taken on a high proportion or important transport function, and concentration of transportation has been increasingly evident. Through quantitative analysis and case study, we found that most of trunk transport lines show ＂3/7 rules＂, that means 30% of transport networks take about 70% of freight volume or mileage.This phenomenon also accords with the experiences of western countries. On this basis of Pareto Improvement thinking and considering expieriences of American and some European countries, we give identification principles of the key transport corridors in China. The findings of this paper are helpful for optimizing comprehensive transport corridors resource allocations, and could be used as a reference for the government to make future strategic transportation planning dicisions.
