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。
In this paper, we select the relevant indexes of railway, highway passenger and freight volume and so on for 15 consecutive years from 2007 to 2010 in 15 central cities in the urban agglomeration of northeast China. By using the analysis method of location entropy model, the dynamic changes of space transportation links in the urban agglomerations of northeast China in recent years are revealed . The results show that the spatial transport links of the urban agglomerations in northeast China show a slight increase in the past four years in general, but the alternation regularity of spatial transport links is strengthened and weakened at different stages of development. The relationship between railway passenger transport links and road passenger transport links , And the contact of freight transport between railways all showed an increasing trend. Only the transport links of road freight showed a slight decrease. The transport links between passengers and passenger transport showed an upward trend while the freight transport links showed a declining trend. However, the relative increase of passenger transport links The trend is weaker than the trend of freight transport links more pronounced.
