Block three-dimensional space form quantitative analysis method

Abstract

The invention discloses a block three-dimensional space form quantitative analysis method, and is suitable for the field of city design. The existing quantitative expression method for the block form,such as plot ratio, block height, building density and the like, is mainly used for controlling the block development and construction strength, and cannot accurately reflect the complex three-dimensional form of the block. The method of the invention comprises the following steps: understanding the form of a block into a wrinkle-shaped surface set consisting of the outer surface of a building inthe block and a site; based on the constructed three-dimensional morphological parameter calculation formula, counting morphological parameters of a block according to the constructed three-dimensional morphological parameter calculation formula; and finally, quantitatively classifying block morphologies by analyzing the surface, the height, the volume and the site expansion of the block to establish accurate association between spatial morphologies and quantitative indexes. The invention provides a scientific and accurate quantification method for the three-dimensional form complex characteristics of the cognitive block form.

Description

technical field [0001] The invention belongs to the field of urban design, and in particular relates to a quantitative analysis method for three-dimensional spatial form of blocks, which is suitable for precise quantitative expression of three-dimensional spatial forms of blocks. Background technique [0002] The cognition of urban form at the mesoscale is mainly developed from the perspective of the block, which has the function of linking the large-scale urban structure and the microscopic building form. The establishment of the relationship between the three-dimensional spatial form of the block and the quantitative indicators through the expression of quantitative parameters is conducive to guiding the internal building shape design of the block and the physical performance control of the block. The current quantitative expression methods for block shape mainly include: [0003] 1. Floor area ratio, building density, building height [0004] In the existing urban and r...
