摘　　要：为科学分析物流经济空间格局,基于经济地理学3D理论的密度(density)、距离(distance)和分割(division)框架,建立了物流经济空间格局的L-3D分析体系,利用地理集中度、物流经济联系强度及区位商等测度指标,分析了云南省物流经济空间格局的密度、距离及分割特征。结果表明:云南省物流经济密度的空间分异特征显著,呈现以昆明为中心的横纵扩散模式,外圈物流经济明显薄弱;物流经济空间距离呈现中心—通道发展模式,滇中城市群发展优势明显,西部边界物流经济距离较大;物流经济分割特征体现于昆明的区位商值较低,滇中城市群物流经济发展差异显著,以昆明为基准,大理及其周边地区分割严重。Logistics is the basic industry of the national economy, the efficient circulation of the material to ensure the operation of the social economy. Yunnan Province located in the southwest occupies the ＂bridge- head＂ for foreign exchange, whose extent of economic development has great influence on capacity of ab- sorbing foreign economies and the depth of external communication. Enhancing the logistics power is signifi- cance in Yunnan province while material exchange becomes as the main form of the world economic commu- nication. To describe the spatial pattern of logistics economy, this paper establishes the L-3D system to analy- sis logistics economic spatial pattern based on 3D theory of economic geography, which covers the frame of Density, Distance and Division. Yunnan province logistics economic space pattern is obtained with indexes of coefficient of geographic concentration, logistics economic linkages and location quotient to analysis the density, distance and division respectively. The results show that the spatial differentiation characteristics are significant in density of logistics economic. A model of vertical and horizontal diffusion with a center of Kunming is revealed. The outer logistics economy is obviously weak. It shows the development mode of cen- ter-channel in division of logistics economic, and development advantages of urban agglomeration in central Yurman is significant. For division, it is weak in spatial distance of logistics economic in the area of western boundary. Kunming is poor for location quotient, and the development of urban agglomeration in Central Yunnan is discrepant. Dali and surrounding areas is serious in this respect. The similarity was found in the distribution of the logistics and economy in space when drawing the characteristics of spatial pattern of Yun- nan Province logistics economy.
