A method for establishing a joint defense and joint control scheme for quantifying atmospheric pollution among different scale areas

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....

AI Technical Summary

Problems solved by technology

[0004] Through the above analysis, the existing problems and defects of the existing technology are as follows: (1) The existing technology lacks a quantitative joint defense and joint control plan, and even lacks a method for formulating a quantitative joint defense and joint control plan

2) The existing technology does not consider the basis for joint prevention and control of cities in different regions or between regions of different scales, and mainly relies on expert consultations to promote the implementation of joint defense and joint control policies, and lacks quantitative scientific theories of joint defense and joint control support

3) Although the existing joint prevention and control technology emphasizes the joint prevention and control during the period of heavy pollution, it still lacks the pertinence and quantitative decision-making methods of joint prevention and control, lacks precision, the effect of joint prevention and joint control is not ideal, and the cost is high. Efficiently realize the improvement of air quality in different cities and regions of different scales

[0005] The difficulties in solving the above problems and defects are: the variability of meteorological conditions and the lack of regularity in the transmission of air pollutants, the time series data of air pollutants have highly nonlinear characteristics, and the concentration data of air pollutants are easily affected by various local sources. Emissions are affected while being affected by off-site transfers

In fact, the analysis of the source of air pollutants in a city is a very complicated scientific issue. Chinese scientists have conducted many studies on key polluted areas in China, but it is still difficult to obtain the precise source of the research results.
