特大城市中心区零售业态三维空间结构研究——基于POI大数据的陆家嘴中心区实例

Research on the Spatial Distribution of Retail Formats of the Megacity:Based upon POI Data of Central Lujiazui

随着增量规划转存量规划趋势的不断加深,我国城市内部规模体系的动态变化程度仍在不断加剧,城市建设由平面扩张转变为向三维方向拓展,城市中心区业态空间结构呈现愈加复杂的变化趋势。在此背景下,国内外学者展开了有关城市中心区业态分布特征的研究,然而由于城市中心区业态的空间分布呈现三维化特征,相关研究仍局限在平面,业态的三维空间分布特征仍未被深入理解。文章试图探索特大城市中心区业态的三维空间分布特征,基于POI大数据,以上海陆家嘴中心区内业态数量最多的零售类业态为例,分析其在平面及三维的空间结构并推导出其空间分布模式,借此为更多城市中心区的存量规划提供蓝本。

As the trend of increments planning turning to maintenances planning is continuing deepening,the degree of the dynamic change of China’s urban internal scale system is still intensifying,and urban construction is changing from plane expansion to three-dimensional expansion,which makes the formats’spatial structure of urban central show a more complex changing trend.Under this background,domestic and foreign scholars have carried out many researches on the distribution characteristics of urban central format.However,due to the three-dimensional characteristics of the spatial distribution of urban central format,relevant researches are still confined to the plane,and the three-dimensional spatial distribution characteristics of urban central format have not been thoroughly understood.Taking central Lujiazui as an example,based on the POI data,we try to explore the threedimensional space distribution characteristics of urban central format of mega-cities.Through field investigation and check of formats data,and obtaining the formats three-dimensional spatial data,we analyze the spatial structure of central Lujiazui in both plane and three-dimensional scales,taking retail formats as an example,and deduce the spatial distribution model of retail formats on this basis,so as to provide a blueprint for the maintenances planning of more urban centrals.
