Urban dense district ventilation corridor building method and device, medium and equipment

Abstract

The invention relates to a method for establishing a ventilation corridor in a dense city district, which comprises the following steps of: counting three-dimensional data of a city, and establishing a three-dimensional model of a city landscape; dividing the three-dimensional model according to grids to form a plurality of distributed three-dimensional models; connecting the plurality of distributed three-dimensional models with Phoenics software to obtain a Phoenics model, designing different parameters for simulation through the Phoenics model to obtain an urban design landscape configuration scheme, and evaluating the urban ventilation effect. According to the invention, detailed ventilation corridor construction thoughts, technical principles, effect verification and the like are provided, and the effectiveness of ventilation corridor construction is improved; therefore, a distributed model construction technology is provided, the problem that the calculation efficiency of the Phoenics model is low is solved, and scientific, feasible and accurate technical support can be provided for related planning.

Description

technical field [0001] The invention relates to a method, device, medium and equipment for establishing ventilation corridors in urban dense areas, and belongs to the field of urban establishment management. Background technique [0002] The urban heat island is a phenomenon in which the temperature in the core area of ​​the city is higher than that in the surrounding areas, and it is very common in today's dense urban areas. It is easy to cause diseases related to high temperature and heat, significantly increase energy consumption and carbon emissions of air conditioning in summer in cities, and increase the concentration of air pollutants. By using urban building materials with high albedo to reduce local hot spots and increase the heat diffusion rate, the heat island intensity of some buildings and areas can be effectively reduced. However, it is too expensive to practice across the city. The construction of urban ventilation corridors and the use of "Natural-based Sol...

AI Technical Summary

Problems solved by technology

Current technical solutions mostly start from building density, while ignoring the cooling effect of green spaces and water bodies;

[0005] (2) Model parameters are not comprehensive

The parameters of the current model mostly start with land use, ignoring the landscape form and ecological impact of three-dimensional buildings and trees;

[0006] (3) Model operation efficiency is low

The current urban-scale heat island effect model is mainly based on large-scale meteorological models, such as WRF, etc., with low accuracy; while urban blocks often use fluid dynamic models, which are extremely computationally intensive and cannot be extended to urban areas

This has led to the establishment of ventilation corridors throughout the city, no suitable model can be used, and the accuracy of simulation prediction is low;

[0007] (4) Poor technical operability

Urban landscape design and planning departments urgently need some feasible technologies to optimize the current landscape, so as to improve the adaptability of the living environment. However, most current schemes do not consider factors such as landscape type and configuration, and cannot meet this realistic demand
