Urban ventilation corridor delimiting method for improving urban climate livable degree

Abstract

The invention discloses an urban ventilation corridor delimiting method for improving urban climate livable degree. The method comprises the following steps of: step 1, delimiting an action space, respectively importing underlying surface data and urban planning land data of an urban current situation into urban meteorological and ecological analysis software, analyzing an urban surface ventilation potential level, identifying an area with a poor urban ventilation environment, obtaining a surface temperature through satellite remote sensing image data inversion, and calculating an area with high urban heat island intensity. In the invention, a complete set of urban ventilation corridors for improving the overall ventilation capacity of a city is established from four aspects of range definition of an action space, identification of a compensation space, construction and verification of the ventilation corridors and management and control of the ventilation corridors. Therefore, the planning result of the urban ventilation corridors by adopting the technical scheme provided by the invention is accurate, the detection is easy, and the management and control are convenient.

Description

technical field [0001] The invention relates to the technical field of urban planning, in particular to a method for demarcating urban ventilation corridors for improving urban climate livability. Background technique [0002] With the rapid increase in the level of urbanization in my country, the scale of urban built-up areas has increased significantly, and the underlying surfaces of cities have become rougher. The wind speed in many cities across the country has generally shown a trend of decreasing year by year. Climate and environmental issues have become increasingly prominent. [0003] Urban ventilation corridors are "channels constructed to introduce fresh, cold and humid air into urban areas for the purpose of improving urban air mobility, alleviating the heat island effect, and improving human comfort." Urban ventilation corridors are conducive to promoting urban air circulation and soothing Summer heat island effect; the research work on the planning of urban vent...

AI Technical Summary

Problems solved by technology

[0004]The traditional urban ventilation corridor planning method can identify ventilation corridors, but it cannot solve the problem of poor ventilation caused by unreasonable space in the current built-up areas and planned new areas The problem is that there is a lack of construction process; secondly, the traditional urban ventilation corridor planning method does not clearly define the boundary of the ventilation corridor. It is only expressed with structural lines, and it is difficult to define the boundaries of the control areas along the corridor, which reduces the operability of planning
