基于建筑大数据的城市三维空间形态研究——以武汉市主城区为例

Urban Three-dimensional Spatial Morphology based on Building Big Data:A Case Study of Wuhan City

城市形态的最基本要素是城市建筑,研究城市形态必然离不开城市建筑。文章基于武汉市主城区建筑高度的数据,运用点格局分析法研究建筑在三维空间中的分布特点。研究表明:(1)武汉市主城区大部分呈现多中心的形式,大部分集聚分布。(2)武汉市主城区建筑格局中部高四周低、西南部普遍高于东北部。(3)建筑高度与大部分公共服务设施成正相关。(4)建筑高度与大部分公共服务设施成正相关。对武汉市主城区城市三维形态的研究,可为武汉市主城区的开发与空间布局提供建设性建议。

The most elements of urban morphology is the urban construction,urban morphology research at the field of city construction.Based on the data of building height in Wuhan City,this paper uses pattern analysis method,so as to study the distribution characteristics urban constructions in the three-dimensional space.The results show that:(1)The main urban area of Wuhan presents a polycentric aggregation distribution pattern,and the main urban area of Wuhan presents an aggregation distribution pattern.(2)The architectural pattern of the main urban area of Wuhan tends to be higher in the central part and lower in the periphery,while higher in the southwest than in the northeast.(3)Building height is positively correlated with most public service facilities.(4)Building height is positively correlated with most public service facilities.
