A method for locking hotspots of urban air pollution

Abstract

The invention proposes a method for locking hot spots of urban air pollution, which belongs to the field of air pollution monitoring. The method of the present invention includes: step 1, establishing grids and numbering the monitoring area; step 2, performing diffusion fitting on the air pollutants in the area based on the Gaussian multi-point source air pollutant diffusion model, and calculating the pollution of each grid in the area at the same time concentration value; step 3, select a grid with the highest concentration of air pollutants as the starting point, and lock an air pollution hotspot area; step 4, select the grid with the highest concentration of air pollutants in the grid set around the starting point grid ; Step 5, use the grid selected in step 4 as a new starting grid; Step 6, judge whether the starting grid is a boundary grid, if so, end this method, if not, continue to step 4. The invention can more accurately lock the air pollution hotspot area, and can more effectively grasp the dynamic process of pollutant diffusion in the area.

Description

technical field [0001] The invention belongs to the field of air pollution monitoring and relates to a method for locking hot spots of urban air pollution. Background technique [0002] With the continuous development of the economic level and the improvement of people's quality of life, the problem of air pollution has gradually become prominent. Air pollution seriously endangers people's health and affects the sustainable and sound development of society. In order to solve this problem, many studies have been carried out around air quality monitoring and air pollution prediction. [0003] The traditional heavy pollution process analysis is a non-standardized method based on the experience of professionals. Different business units or scientific research units have different methods for heavy pollution process analysis. The existing technical means focus on the monitoring area Forecast of the time or intensity of heavy pollution. [0004] Due to the lack of technical res...

Problems solved by technology

[0003] The traditional heavy pollution process analysis is a non-standardized method based on the experience of professionals. Different business units or scientific research units have different methods for heavy pollution process analysis. The existing technical means focus on the monitoring area Time or Intensity Forecast of Severe Pollution Occurrence

[0004] Due to the lack of technical research on using the data obtained from air pollution monitoring to lock the pollution hotspots in the region, there is a need for a method to lock the urban air pollution hotspots in order to better control the air pollution problem.
