Problems solved by technology

At present, the formulation of urban floor area ratios in my country relies on planners using human brains, which leads to subjectivity and randomness in the determination of floor area ratios, not to mention the neglect of noise and other related environmental factors during the formulation process

Embodiment

[0030] Embodiment: a kind of urban floor area ratio optimization method based on noise zoning model, such as figure 1 As shown in the figure, take Nanjing Xinjiekou Central District as an example for specific analysis:

[0031] 1) In the target area, through the field survey of the central area of ​​Xinjiekou, combined with remote sensing images picture , using painted picture The software (AUTOCAD) establishes the urban geographic information module to record the spatial form data of the city in units of blocks:

[0032] 1.1) In this case, the spatial data of urban streets, blocks, and buildings in the central area of ​​Xinjiekou, Nanjing are mainly obtained through the electronic terrain files in dwg format produced by the surveying and mapping department and satellite aerial photos such as Google Earth. picture The artificial vectorization was completed, and the updated data on the buildings in the block and the surrounding environment, the number of building floors, and...

Abstract

The invention relates to a noise zoning model based city floor area ratio optimization method. The method includes: recording city space shape data in a target zone; establishing a sound source instant acquisition database; connecting the sound source instant acquisition database and a geographic information module; partitioning a noise zone into four types of zones; establishing a city noise zoning model; establishing a floor area ratio optimization module; performing noise simulation on the target zone through the zoning model according to a floor area ratio index in the target zone; and comparing simulation noise and noise demands of relevant laws and regulations, and then performing optimization on the floor area ratio. Based on a geographic information system and a city coordinate system, the method combines sound environment data information and a computer database, establishes the city noise zoning model, provides a floor area ratio optimization measurement through noise prediction of the target zone, and optimizes a city sound environment by combining noise control and the space shape design. The method solves the problem of neglect of noise influence during determination of the floor area ratio in the prior art, and the formulation of the floor area ratio is scientific and reasonable; and a method for determining the floor area ratio of city communities based on noise optimization is provided.

Description

technical field [0001] The invention relates to the technical field of urban planning, in particular to a method for optimizing urban floor area ratio. Background technique [0002] With the continuous acceleration of my country's urbanization process and the rapid development of cities, environmental issues have become more and more important issues in urban development, hindering the sustainable development of cities. The noise problem is a product of the rapid development of the city and the continuous expansion of the scale. Many scholars have proved that the distribution of urban acoustic environment is closely related to the content of urban planning disciplines such as the city's road traffic system, block land development, and the shape and texture of land plots. contact. Although there are many theoretical studies at present, there is a lack of practical application, and there is still a lack of adjustment and optimization of noise from the perspective of volume ra...
