Abstract

The invention discloses an economic floor area ratio calculation method based on a land economic mathematical model. The method comprises the following steps: acquiring a preset urban land parcel model map, wherein the urban land parcel model map at least comprises a land parcel map layer and a building map layer; finding a land parcel to be calculated from the land parcel map layer, and recognizing buildings included in the land parcel to be calculated in the building map layer; calculating an area S<d> of the land parcel to be calculated and floor areas S<k> of buildings included in the land parcel to be calculated; acquiring floor numbers G<k> of the buildings included in the land parcel to be calculated, and a housing price Z, a housing removal and compensation ratio H, an infrastructure unit price M, an entire-cost comprehensive unit price N and a development gross profit V in the land parcel to be calculated; and calculating an economic floor area ratio Far of the land parcel to be calculated according to a mathematical model shown in the description. The invention also discloses an economic floor area ratio calculation system based on the land economic mathematical model. Through adoption of the method and the system, the economic floor area ratio of the land parcel to be calculated is calculated; a calculation process is simplified; and the cost is lowered.

Description

technical field [0001] This application relates to the field of road traffic, in particular to a method and system for calculating economic floor area ratio based on land economic mathematical model. Background technique [0002] FAR is an important tool to regulate the development factors of urban land economy, resources, society, environment, etc., and has attracted the attention of the government, developers, urban residents, and other social parties. The relationship between land development volume ratio and urban road traffic is very close: if the volume ratio is too high, it will easily cause road traffic congestion, and the road traffic carrying capacity needs to be increased accordingly; . [0003] However, in the current urban planning, due to the lack of scientific quantitative calculation methods for the formulation of the floor area ratio, there is insufficient research on the feasibility of the road traffic carrying capacity of the floor area ratio. Especially...
