Abstract

The invention discloses an automatic dividing method of a city plot ratio, which comprises the following steps: utilizing an information-processing system taking a high performance computer as a core, taking geography data of a city downtown as model input data, taking city blocks as model process evaluation base maps, building a city plot ratio evaluation model, carrying out standardized revise through a Saaty method, determining the plot ratio numerical value of each block, and automatically outputting engineering drawings that can be directly used in the city overall planning through drawing equipment. The method overcomes the insufficiency that the subjectivity and the randomness exist when the city plot ratio division is carried out by utilizing the human brain intellectual activity to make a decision in a city construction project, and greatly improves the working efficiency.

Description

technical field

[0001] The invention relates to a method for automatic zoning of urban floor area ratio, which belongs to the technical field of urban planning. Background technique

[0002] In the current stage of rapid urbanization, the disorderly spread of urban construction land has caused serious traffic problems, and also caused a waste of valuable land resources and construction funds. The existing urban floor area ratio zoning technology mainly relies on planners to use human brains to conduct comparative analysis of a large number of zoning schemes. There are problems in that the work is mainly technical operations, the technical results are highly random, and the work efficiency is low.

[0003] FAR is the core of quantitative control indicators in regulatory detailed planning, a "sensitive" factor to measure the intensity of land development, and an issue of research value in urban planning practice. At present, when the construction market is not perfect, the fl...
