在有关建筑总平面规划指标中,尚没有定量描述建筑群高低错落状况的。这里的高低系指建筑群的平均高度,错落系指不同建筑物之间高度上差异的程度。本文构筑了两个新指标,即平均高度和高度偏差值,它们分别反映了建筑群的高低和错落状况。平均高度、建筑密度和容积率之间,以及平均高度、高度偏差值和建筑物最大(小)层数之间有简单的数学关系。作为现有的容积率和建筑密度指标的补充,平均高度和高度偏差值从一种新的角度反映了建筑群的空间状况,对科学管理城市建设具有重要意义。
In the overall planning of the building plan indicators, there is no quantitative description of the status quo of buildings scattered. Here refers to the level of the average height of buildings, patchwork refers to the difference between the height of different buildings. This article constructed two new indicators, namely, the average height and height deviation values, which respectively reflect the height and patchy status of the buildings. There is a simple mathematical relationship between the average height, building density and floor area ratio, as well as the average height, height deviation values and the maximum (small) number of floors in a building. As an addition to the existing index of floor area ratio and building density, the average height and height deviation values reflect the spatial status of buildings from a new perspective, which is of great significance to the scientific management of urban construction.
