东北城市密集区空间运输联系演变规律分析

选取东北城市密集区15个中心城市2007-2010连续四年的铁路、公路客货运输量等相关指标,利用区位熵模型的分析方法,揭示了近年来东北城市密集区空间运输联系的动态变化规律。研究表明:东北城市密集区空间运输联系近4年来总体上呈现出小幅度增强态势,但在不同发展阶段又表现出空间运输联系增强与减弱的交替变化规律;铁路旅客运输联系、公路旅客运输联系、铁路货物运输联系均呈现出加强的态势,仅公路货物运输联系则呈现出小幅度减弱的态势;旅客运输联系呈现上升趋势,货物运输联系则呈现下降态势,但相对而言,旅客运输联系增强的趋势比货物运输联系减弱的趋势更为显著。

Evolution of spatial transport linkage in the city concentrated area in Northeast

Railway passenger,highway passenger,freight traffic and other related indicators of 15 central cities in the northeast city concentrated area were selected and spatial transport linkage model analysis methods were used to reveal the dynamic variation of the space contact in the northeast city concentrated area.Research shows that the transport linkage in nearly 4 years overall presented small amplitude increase trend,but in different stages of development it showed spatial transport linkage enhancement and attenuation of alternation.Railway passenger transportation links,highway passenger transport links,railway goods transport links were exhibited enhanced posture,only highway cargo transportation links showed a small amplitude weaken;passenger transport links presented the trend of escalation,transport of goods contact showed a downward trend,but relatively speaking,enhancement tendency of passenger transport linkages was more obvious than transport of goods contact decrease.
