Abstract: There had records of special strong dust storm in Beijing since 400 A D. During the high frequent occurring periods of special strong dust storm in Beiwei, Min and Qing dynasties, the special strong dust storm often occurred in arid climate condition, but there were some exception examples. The period of special strong dust storm occurrence had a directional relationship with the land's development and the destruction of trees nearby Beijing. Since Beijing became the capital of new China, the government had been paying attention to control environment, so the dust climate in Beijing decreases, particularly the special strong dust storm does not exist nearly.

Key words: Beijing, blown sand, dust storms, control
