Study on Gray Numerical Model of Air Pollution in Wuan City

摘要

In connection with the uncertainty problem of pollutants diffusing in the atmosphere of Wuan 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 Wuan city, and simulates SO_2 and PM_(10) 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 Wuan city.
