| 摘 要： | 根据生态学中的Logistic方程,建立城市交通运输方式共生演化模型,并讨论城市交通运输方式共生演化机制.同时以长株潭地区为例.实证各交通运输方式间的共生关系.得出:共生演化实质是城市交通系统和城市生态系统藕合而成的复杂适应系统,其发展受利益驱动机制和生态平衡机制的双重制约;三城市的主导交通运输方式以及"人与自然和谐共处"为原则,为地方政府管理交通运输系统的稳定发展有一定的指导性意义.

| Abstract: | According to the Logistic equation in ecology,the symbiotic model of urban transportation mode and its evolution mechanism were discussed.Taking Chang-Zhu-Tan district as an example,the symbiotic relationship between transportation modes was proved,and the dominant transportation mode in three urban was obtained.The results show that the essence of evolving is a complex adaptive system resulting from the interaction between urban transportation system and urban ecosystem,whose development is restricted by b... |
