【摘要】：为更客观评价综合运输通道各种运输方式的协调发展水平,运用耦合理论和协调理论,从动力源、作用表现、实现过程3方面解析通道交通方式耦合机理。通过引入容量耦合概念及容量耦合系数模型,以耦合度与协调度为输入变量,构建耦合协调度模型,以广州-湛江综合运输通道为例进行实证计算分析。研究结果表明:通道运输方式存在极强的耦合交互关系,表现为正向促进、负向制约、联动共生、叠加放大的耦合作用;广州-湛江运输通道2008~2012年的系统耦合协调度分别为0.345 0、0.346 4、0.397 2、0.420 3、0.472 5,呈现逐年递增趋势,但总体协调水平较低,均小于0.5,处于濒临失调到基本协调过渡的发展阶段。这与现实相符,表明模型可信。
[Abstract]:In order to evaluate the coordinated development level of various transportation modes in integrated transportation channels more objectively, the coupling theory and coordination theory are used to show the effect from the power source. Through introducing the concept of capacity coupling and capacity coupling coefficient model, taking coupling degree and coordination degree as input variables, the coupling coordination degree model is constructed. Taking the Guangzhou Zhanjiang integrated transportation corridor as an example, the research results show that there is a strong coupling interaction between the channel transportation mode, which is characterized by positive promotion, negative constraints, and linkage symbiosis. Coupling of superimposed amplification; The system coupling and coordination degree of Guangzhou Zhanjiang Transportation Channel from 2008 to 2012 is 0.3450 / 0.346 4 / 0.397 / 2 / 0.420 / 3 / 0.472 5, respectively. There is an increasing trend year by year, but the overall coordination level is lower than 0.5, which is in the stage of development from being on the verge of maladjustment to the basic coordination transition, which is consistent with the reality and shows that the model is credible.

【正文快照】： 0引言近年来,中国交通运输一直保持高速发展态势,各种交通运输方式的规模总量已位居世界前列。但与此同时,各种运输方式抢占交通资源、重复建设、不合理竞争、不协调发展等问题也日渐突出,尤其是在综合运输通道中更为明显[1]。交通运输的发展重点需要从规模总量扩张转向各种运
