中文摘要：

基于动态和静态、定性和定量的分析方法，在GIS平台上，构建了区位几何中心指数、时空耦合指数，从中微观尺度研究、测度芜湖城市专业批发市场的区位演化及其与城市物理空间拓展的时空耦合关系，归纳揭示城市专业批发市场区位选择的一般机制。结果表明：芜湖城市专业批发市场的空间区位演化与城市物理空间拓展方向基本耦合；芜湖城市专业批发市场呈离心状圈层分布于城市近郊区，其空间分布主要受城市空间功能演化与置换、地价、交通、人口等因素的影响。

英文摘要：

Wholesale market plays a very important role in our economy life, The paper bases on the platform of GIS, build the index of Geometric center and the index of spatial-temporal coupling, analyzes the coupling relationship between the urban spatial expansion and the evolution of urban specialized wholesale market location, It is summarized that： the spatial distribution evolution of urban specialized wholesale markets in Wuhu and urban spatial evolution is coupling; The factors of specialized wholesale markets distribution in Wuhu are functional conversion of urban space, traffic, population and the price of land; specialized wholesale markets show centrifugal layer distribute in suburb area.
