AI Technical Summary

Problems solved by technology

The simulation of thermal comfort and pollutants in the existing technology cannot quickly locate the environment in which it is located, and cannot be compared and analyzed in real time with the monitoring data
In addition, limited by computer data processing capabilities, ENVI-met software can usually only simulate the microenvironment for a period of time

Embodiment Construction

[0039] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0040] This embodiment provides a method for establishing a real-time perception map of urban thermal environment and air pollutant concentration, including the following steps:

[0041] S1, with the monitoring point as the center, obtain the vector map in the calculation domain of 1000m×1000m. In this embodiment, the monitoring point of the News Building is taken as an example, and the simulation area is as follows figure 1 As shown, information such as roads, buildings, and green spaces are recorded; based on the simulation area, a 3D model is established in ENVI-met, and different model attributes are distinguished. The model attributes include buildings, ground, atmosphere, vegetation, and soil. , water bodies, etc., such as figure 2 shown.

[0042] S2, performing grid division on the 3D model, and determining the grid size of each model...

Abstract

The invention discloses an urban thermal environment and air pollutant concentration real-time sensing map establishment method, which comprises the following steps of: simulating an urban thermal environment and air pollutants by utilizing ENVI-met software, drawing a thermal comfort cloud picture and an air pollution cloud picture, automatically displaying the cloud pictures and parameters in an electronic map of ArcGIS software through programming and definition of picture coordinates, and establishing a real-time sensing map of the urban thermal environment and the air pollutant concentration. A thermal environment and air pollutant sensing map is formed, and real-time simulation of the urban microenvironment is achieved. According to the invention, real-time map display can be carried out on urban thermal environment and air pollutants, and data support is provided for reasonable planning and improvement of urban regional microenvironment.

Description

technical field [0001] The invention relates to the technical field of urban air pollution and microclimate, in particular to a method for establishing a real-time perception map of urban thermal environment and air pollutant concentration. Background technique [0002] The increase in urban volume and density has led to large-scale changes in land cover types, which have damaged the urban surface microclimate. Urbanization is not only directly related to the intensification of the urban heat island effect, but also complicates the type of the original underlying surface of the city and continuously increases the urban roughness, resulting in a decrease in the turbulent heat transfer inside the urban boundary layer and changing the urban canopy area at multiple scales. Climate environment, resulting in five special local climate effects: heat island, wet island, dry island, rain island, and turbid island. The heat island effect and the temperature inversion layer effect wea...
