Abstract

The invention belongs to the technical field of air quality management, and discloses a method for establishing a joint defense and joint control scheme for quantifying atmospheric pollution among different scale areas, which comprises the following steps: establishing a characteristic variable database required by a new method of a joint defense and joint control scheme system for atmospheric pollution among cities and different scale areas; performing machine learning and data mining on the feature variables in the database by adopting big data mining methods such as clustering analysis anda network association model; for pollution conditions of different pollutants, different pollution periods, different pollution levels and different scale areas or cities, designing correlation thresholds and corresponding joint defense and joint control city groups or different scale area groups. According to the invention, more accurate joint defense and joint control can be realized for atmospheric pollution among cities or areas with different scales in different areas, air quality improvement of different cities and areas with different scales can be realized more efficiently, and air quality can reach the standard as soon as possible, so that the health of people can be protected.

Description

technical field

[0001] The invention belongs to the technical field of air quality management, and in particular relates to a method for establishing a quantitative joint prevention and control scheme for air pollution between regions of different scales. Background technique

[0002] At present, there are many existing pollutant prevention and control systems. For example, the method invention patent "Indoor Environmental Pollution Prevention and Control System" with the patent number of 201710762642.9 discloses a method for monitoring, evaluating and evolving indoor environmental quality; For the 201220604879.7 use of the new patent "environmental emergency three-level prevention and control system" disclosed a feasible solution to corporate environmental pollution. However, there is no systematic method suitable for formulating quantitative and grading schemes for different air pollutants in different scale regions in the existing pollutant prevention and control schemes....

Examples

Embodiment

[0060] Establish PMs for 41 prefecture-level cities in the Yangtze River Delta in 2018 2.5 Pollution refinement joint prevention and control program system

[0061] (1) Selected study area and data preparation

[0062] Select 41 prefecture-level cities in the Yangtze River Delta such as figure 2 shown. Atmospheric PM obtained from China National Environmental Monitoring Station 2.5 For hourly concentration data, the population data and area data are obtained from the National Statistical Yearbook, and these data are stored in the database. figure 2 Geographical location map of 41 prefecture-level cities in the Yangtze River Delta region.

[0063] (2) The method used in this implementation case

[0064] 1) Calculation of the exposure intensity of the pollutant population

[0065] The population exposure intensity can reflect the risk of the population being exposed to pollutants, and is calculated by multiplying the population density by the pollutant concentration. Th...
