Atmospheric pollutant source contribution degree obtaining method and device, equipment and medium

Abstract

The invention discloses an atmospheric pollutant source contribution degree obtaining method and device, equipment and a medium. The method comprises the following steps: obtaining atmospheric monitoring parameter data of a target point location in the current period; acquiring atmospheric monitoring parameter data of the target point location in the same historical period of the last year; performing regression analysis on the atmospheric monitoring parameter data in the current period and the atmospheric monitoring parameter data in the same historical period of the last year to obtain influence coefficients of the atmospheric monitoring parameters; and calculating the atmospheric pollutant source contribution degree by utilizing the atmospheric monitoring parameter data of the current period and the influence coefficient. Each atmospheric monitoring parameter data of the target point location is associated with each influence coefficient to calculate the atmospheric pollutant sourcecontribution degree, and the method is small in data demand, easy to obtain and simple in data processing, can effectively judge the influence weight of each atmospheric monitoring parameter, and cancompletely meet the requirements of analyzing the local contribution degree, the meteorological change contribution degree and the regional transmission contribution degree.

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
