| 摘 要： | 民勤地区是中国沙尘暴发生年频次最高的地区。本文讨论了干旱、地震、古湖泊和风线对民勤地区沙尘暴形成所产生的综合作用。强地震破坏了土壤颗粒的团聚性,古湖泊环境提供了沙土混杂的地表层,风线决定了沙尘暴的飞扬和运移。

| Abstract: | The Minqin region is prone to dust storm. The integrated effects of drought, earthquake, paleo-lake and wind line on the origin of dust storms are discussed in this paper. Strong earthquakes destroy the consolidation of soil particles and the circumstance of paleo-lake supplies mixture of sand with soil. The climate and wind line determine the flying up and movement of dust storm. |
