基于物流空间相互作用模型的铁路运输通道负荷测算

Measuring Railway Transportation Corridor Load Based on Spatial Interaction Model of Logistics

铁路运输通道是区域之间空间相互作用特征的表现实体之一。本文以Wilson空间相互作用模型为基础,从原理的角度、通过理论演绎建立物流空间相互模型,根据模型构造出"相互作用负荷"参数,并使用该参数对我国铁路货物运输通道负荷进行测算。基于"相互作用负荷"参数而对铁路运输通道负荷状态的描述、评价可为铁路运输网络规划、建设提供有力的决策支持。

Railway transportation corridor is one of the expressional entities of spatial interaction among different economic regions which produce certain demand for railway transportation. Based on Wilson spatial interaction model, the paper has designed a spatial interaction model of logistics by theoretically deduction. A parameter called Interaction Load was constructed through the spatial interaction model of logistics. Interaction Load was employed to measure the load of railway transportation corridor in China, which is beneficial to the planning and the construction of railwav network.
