【摘要】：综合考虑交通网络和地理环境因素,分别从动态、静态角度改进传统的空间相互作用模型,即采用多指标测度区域经济综合实力,以考虑地形起伏的交通距离作为通达距离,通过交通流量、道路属性特征、地形条件修正模型系数,构建了考虑交通和地理环境因素的空间相互作用模型。以山东省为例进行实证分析,并与传统模型比较,检验改进模型在实际应用中的有效性。研究结果表明:交通可达性对空间相互作用具有引导性;交通设施配置和区位对区际联系的影响不容忽视;改进模型更加合理有效,更具应用价值。
[Abstract]:Considering the factors of traffic network and geographical environment, the traditional spatial interaction model is improved from the dynamic and static angle respectively, that is, the comprehensive strength of regional economy is measured by using multiple indexes, and the distance of traffic with undulating terrain is considered as the distance of access. Through traffic flow, road attributes, terrain condition correction model coefficient, a spatial interaction model considering traffic and geographical environment factors is constructed. Taking Shandong Province as an example, the model is compared with the traditional model. The results show that the traffic accessibility has a guiding effect on spatial interaction, the influence of traffic facilities allocation and location on the inter-regional relationship can not be ignored, the improved model is more reasonable and effective. It has more application value.
