在代谢生态学理论的基础上,提出了综合交通运输体系运量需求的代谢演化模型.模型中城市各种交通方式的运量增长率或变化率不仅依赖于反映城市自身规模的人均GDP,而且受到运输方式间的竞争与合作关系的制约.对中国城市的实证分析结果表明:铁路旅客交通需求量变化率方程中的异速增长指数略大于生态代谢理论中预测的1/4值,而公路旅客运输需求量变化率方程中的异速增长关系并不明显,中国城市公路交通需求的变化率主要受到运输方式间竞争与合作关系的影响.
Based on the theory of metabolic ecology, a metabolic evolutionary model is proposed that integrates the traffic demand of transportation system, and the growth rate or rate of traffic growth of various modes of transport in the model depends not only on per capita GDP reflecting the size of the city itself Which is constrained by the competition and cooperation among modes of transportation.The empirical analysis of Chinese cities shows that the allometric growth rate of the rate of change of railway passengers’ traffic demand is slightly larger than the predicted value of 1/4 in the theory of ecological metabolism, The allometric growth of passenger transportation demand rate of change equation is not obvious. The rate of change of urban road traffic demand in China is mainly affected by the competition and cooperation between modes of transport.
