摘要: 西北地区是我国沙尘暴发生次数频繁、发生强度最大的地区,近年来发生的大沙尘暴源地均位于新疆、甘肃和内蒙古的干燥沙漠或戈壁地带。由这些地区起源的沙尘既对全球气候有影响,又对全球化学物质的循环有重要意义。该地区荒漠化严重,已成为全球四大沙尘暴高发区之一的中亚沙尘暴区的重要组成部分,文中综合论述了中国西北地区沙尘气溶胶的源和汇与输运过程,概括性总结了近20多年来对西北地区沙尘暴的研究成果。

关键词: 气溶胶, 沙尘暴, 源与汇

Abstract: The northwest China is one of the areas suffered from high frequency and high intensity of sandstorms. In recent years the source of severe sandstorms often located in Xinjiang, Gansu and Neimenggu. These areas, due to their severe desertification status, had become the main component of the middle Asia Sandstorm Area, one of the four high frequently happening sandstorm areas in the world. The sands and dusts from these areas not only influence the global climate but also have significance on global chemical substance cycle. The convergence and divergence and the transportation of aerosol in northwest China were summarized in the paper. Moreover the research achievement on sandstorm in northwest China in the recent 20 years was reviewed.

Key words: aerosol, sandstorm, convergence and divergence
