| 摘 要： | 北京地区公园440年开始就有强沙尘暴的记录，经过北魏，辽金和明清时期等几个强沙尘暴频发期，北京强沙尘暴多数出现在干旱时期，也有例外，强沙尘暴出现的时间与周围土地的开垦和周围森林植被的破坏有着直接的关系。北京成为新中国首都以来，注重环境的治理，风尘天气减少，特别是强沙尘暴几近消亡。

| Abstract: | The records on special strong dust storms in Beijing were conducted since 400 A D. During a few periods of special strong dust storms high frequently occurring in Beiwei, Min and Qing Dynasties, the special strong dust storms often occurred in period of arid climate, but there were some exceptions. The periods of special strong dust storms occurring have a directional relationship with the land development and destruction of trees in nearby regions of Beijing. Since Beijing became the capital of new China, the government pays attention to environment control. The dusty climate in Beijing decreases, particularly the special strong dust storm does not exist nearly. |
