Abstract :
In view of the uncertainty problem of pollutants diffusing in the atmosphere of Handan city, we monitor and put forward a new conception about air ground pollution belt, and get two-dimensional finite difference equation of air pollution. Meanwhile dispersion coefficient and wind speed are considered as grey parameters. One grey numerical quality model of air pollution is built according to grey theory and applies to the air pollution diffusing system of Handan city, and simulates SO2 and NOx during heating times and unheating times. The result shows the gray numerical model is suitable for application. Meantime, according to the simulation result, put forward the control measures of air pollution in Handan city.
