Locking method for urban air pollution hot spot region

Abstract

The invention puts forward a locking method for an urban air pollution hot spot region, and belongs to the field of air pollution monitoring. The method comprises the following steps that: S1: establishing and grid and carrying out numbering on a monitored region; S2: on the basis of a Gaussian multi-point-source air pollutant diffusion model, carrying out diffusion fitting on air pollutants in the region, and meanwhile, calculating the concentration value of each grid pollutant in the region; S3: selecting the grid with the highest air pollutant concentration as a starting point, and lockingan air pollution hot spot region; S4: selecting the grid with the highest air pollutant concentration value in a grid set around the starting point grid; S5: taking the grid selected in S4 as a new starting point grid; and S6: judging whether the starting point is a boundary grid or not, if the starting point is the boundary grid, ending the method, and otherwise, continuously executing S4. By useof the method, the air pollution hot spot region can be accurately locked, and the dynamic process of the pollutant diffusion in the region can be more effectively mastered.

Description

Technical field [0001] The invention belongs to the field of air pollution monitoring, and is a method for locking hotspot areas 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 sustained and sound development of society. In order to solve this problem, many studies have been carried out around air quality monitoring, air pollution forecasting and so on. [0003] Traditional heavy pollution process analysis is a non-standardized method based on professional experience. Different business units or scientific research units have different methods for heavy pollution process analysis. The existing technical methods focus on the monitoring area. Forecast of the time or intensity of severe pollution. [0004] Due to the lack of existing research on the us...

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.
