Abstract

The invention discloses a gaseous pollutant positioning method, and belongs to the technical field of atmospheric environment. The method comprises the steps of acquiring remote sensing data and a gaseous pollutant emission list, and determining a pollutant concentration high-value region according to the remote sensing data and the gaseous pollutant emission list; acquiring a remote sensing image, and determining a pollution source according to the remote sensing image; then, according to the pollution source, simulating by utilizing an air particle diffusion track model to obtain probabilitydistribution of a pollution air mass in a pollutant concentration high-value region, and according to the probability distribution, obtaining a contribution value of the pollution source to the pollutant concentration; and simulating by using a small micro-scale model in a pollutant concentration high-value region to obtain a pollutant diffusion result. The method aims at overcoming a defect thatin the prior art, accurate positioning of pollutants in the whole region cannot be achieved, the pollutant concentration high-value region can be rapidly positioned, fine simulation can be performedon the pollutant concentration high-value region, and then accurate positioning of the pollutants in the whole region is achieved.

Description

technical field [0001] The invention relates to the technical field of atmospheric environment, and more specifically, to a method for locating gaseous pollutants. Background technique [0002] In recent years, air pollution has become one of the most socially concerned issues. It is particularly important to effectively carry out early warning and prevention of air pollution, quickly locate the location of pollution and predict its diffusion capacity. Atmospheric environmental impact prediction is the use of mathematical models or simulation tests to calculate or estimate the impact of the pollution factors of the evaluation project on the quality of the atmospheric environment in the evaluation area. The commonly used atmospheric environmental impact prediction method is to simulate the physical and chemical mechanisms of pollutants transport, diffusion, transformation and removal in the atmosphere under various meteorological conditions and terrain conditions by establish...
