基于耦合协调度模型的综合运输体系支撑力研究

摘要

通过构建以塔式结构为框架的综合运输支撑力指标体系,得出各子系统的综合发展程度.结合系统间耦合协调度,明确了体系支撑力的计算办法,并对2010—2014年四川省综合运输体系支撑力情况进行了分析.结果表明:四川省综合运输系统支撑力与区域经济虽然态势可观,但支撑力对其满足程度有削减趋势,后期出现了一定的疲软倾向,应加快完善综合运输体系的运营模式,最大限度发挥各交通方式的效率,真正形成多元化、全方位的综合运输体系.%The paper establishes a tower-structure-based indexing system for the supporting capability of comprehensive transportation system. The degree of synthetic development of each subsystem is obtained, and the calculation method of the supporting capability is defined. We then analyze the supporting capability of the comprehensive transportation system in Sichuan Province from 2010 to 2014. Results reveal that the coupling coordinate and the supporting capability continues to increase but the growth rate becomes low in the recent years. The results indicate the importance of maximizing the efficiency of various transportation modes for the fast development of comprehensive transportation systems.
