摘　　要：货物运输联系网络的空间特性能够为区域物流规划与货运交通组织提供基础依据。为高效提取城际货物运输联系的复杂交互关系,基于空间尺度重构理论,在提出货物运输联系网络构建方法的基础上,运用GIS空间分析技术,从网络空间组织过程及网络层级结构两个角度揭示了货物运输联系网络形成的动态性特征,并以云南省为实例地区进行演示;进一步在考虑交通因素的前提下,选取相关性分析和复杂网络分析工具,从强化运输联系和提高运输网络稳定性的角度对其空间组织进行了优化。结果表明:(1)货物运输联系网络的空间组织是一个地域集中性和区域择优性的复杂作用过程,它的节点倾向于与其地理空间邻近的省外城市以及省外区域经济中心取得首位联系,在这个过程中随着网络层级的降低,网络中关键节点的控制力逐渐转移至次级节点,致使城市功能和作用的空间分异趋于均衡;(2)公路交通基础设施网络规模、等级及可达性的变化对城市间货物运输交流的强化作用较弱,运输能力的提升才是其空间组织优化的关键;(3)城际货物运输对网络中关键节点的依赖程度极大,网络层级越高其对蓄意攻击的抗毁程度越低,提升核心网络中关键节点的抗毁性,能够优先实现平衡网络整体连通性和提高货运系统稳定性的目标。The spatial characteristic of freight transport connection network can provide a basis for regional logistics planning and freight transport organization. In order to extract the complex interrelations in inter-city freight transport connections effectively,the theory of spatial scale rescaling is introduced for the method of constructing freight transport connection network,by applying the GIS spatial analysis technology on spatial organization process and hierarchical structure of network,the dynamic features of freight transport connection network forming is explored,and Yunnan Province is taken as an example for demonstration. Then,on the premise of considering the transport factors,the method of correlational analysis and complex network are used to optimize its spatial organization from the perspective of strengthening transport connection and improving transport network stability. The result indicates that( 1) spatial organization of freight transport connection network is a complex process that involves geographic concentration and regional preferentialorientation,its nodes tend to make the first contact with the geographical adjacent city and regional economic center outside the province,in this process,the control power of key nodes in the network will transfer to secondary nodes with the decrease of its hierarchy,causing the spatial differentiation of urban functions to be balanced;( 2) the changes of scale,grade and accessibility of road transport infrastructure network have a weak impact on strengthening intercity freight connections,the crux of spatial organization optimization is improving transport capacity of it;( 3) the inter-city freight transport connections heavily rely on the key nodes in the network,the higher the network level,the lower degree the destruction to intentional attack,the enhancement of survivability of key nodes in core network will achieve the goals that both balance the network connectivity and improve the stability of freight system preferentially.
