摘　　要：本文从细微粒子污染导致灰霾形成的角度出发,首先开展了灰霾监测实验,并对实验数据进行频数和描述性分析,研究了以PM_(10)为主的细微粒子污染与灰霾的影响关系。确定了以PM_(10)日平均浓度为灰霾日的判定依据,并根据中国大陆PM_(10)污染指数的分级标准建立了灰霾等级指数,从而形成了一套根据PM_(10)日平均浓度来确定不同等级的灰霾发生概率的方法,为灰霾预测及灰霾治理提供一定的理论依据。Based on the view that the haze results from the serious pollution of fine particles, the experiments on haze are made, and experimental data are statistically analyzed in descriptive and frequency in this paper, to get the relation between fine particles and the haze. So the PM10 daily average concentration is confirmed as the index for distinguishing the haze. And then the haze grade with five levels is established according to PM10 API classification in Chinese Mainland. A method of predicting the occurrence of haze is presented, of which probability of the haze occurrence with different levels is predicted according to PM10 daily average concentration. And this method will supply certain theory for predicting and preventing the haze.
