Acquisition method, device, equipment and medium of air pollutant source contribution degree

Abstract

The present application discloses a method, device, equipment and medium for obtaining the contribution degree of air pollutant sources. The method includes: obtaining the atmospheric monitoring parameter data of the target point in the current period; obtaining the same historical period of the target point in the previous year Atmospheric monitoring parameter data; To the atmospheric monitoring parameter data of the current period and the atmospheric monitoring parameter data of the same historical period of the previous year, regression analysis is carried out to obtain the influence coefficient of each atmospheric monitoring parameter; using the current Atmospheric monitoring parameter data and the influence coefficient of the period are used to calculate the contribution degree of air pollutant sources. The method of the present application correlates the data of each atmospheric monitoring parameter of the target point with each influence coefficient to calculate the contribution degree of the source of atmospheric pollutants. The data demand is small and easy to obtain, and the data processing is simple, which can effectively judge the influence of each atmospheric monitoring parameter. The impact weight can fully meet the requirements of analyzing local contribution, meteorological change contribution and regional transmission contribution.

At present, the factors affecting the concentration of air pollutants are complex and difficult to quantify simply. However, there are currently few methods for quantitative analysis of air pollutants, especially for areas with few monitoring methods and weak regional environmental protection foundations. Environmental Policy Formulation and Implementation

[0003] The concentration of pollutants in the atmosphere is mainly affected by three aspects: local emissions, regional transmission, and meteorological factors. Through the air quality model, the pollutant discharge list and meteorological data can be input to simulate the concentration of pollutants at the target point, and then analyze the pollution. However, this method has high requirements for emission inventory and meteorological data, a large amount of calculation, and insufficient ease of use, which cannot meet the needs of daily pollution analysis in areas with weak environmental protection foundations.

In the prior art, the air quality model used to analyze the contribution of regional transmission and meteorological factors requires a large amount of calculation, and at the same time requires accurate and high-precision air pollutant emission inventory data and meteorological data, and the "ease of use" of the air quality model Outstanding, unable to meet the long-term and real-time air pollution analysis needs in areas with weak environmental monitoring foundation
