Abstract: Haze is regarded as one of the important indicators of air quality evaluation. And accurate prediction and analysis of haze are considered toprovide theoretical support for relevant government departments to make correct decisions. Various kinds of suspended particles exceeding the standard in the atmosphere are collectively referred to as haze, and the influencing factors are divided into pollutant concentration and meteorological factors. This paper in which PM2.5 and PM10 are represented as suspended particles and SO2, CO, NO2 and O3are regarded as the relevant factors of pollutant concentration is mainly used to discuss the influence of pollutant concentration on suspended particles.

Key words: grey system; interval grey number; kernel and degree of greyness; MGM(1,m,N) model; haze
