摘要: 对历史时期我国沙尘暴发生的特点进行初步总结的结果显示:自汉代之后,沙尘暴发生的范围开始向东扩展,至元明清时期,其发生范围扩展到几乎整个华北地区。这一发展趋势虽与气候的冷暖干湿变化密切相关,但农业经济开发活动向西北地区的转移也是重要原因之一。

Abstract: The characteristic of sand-dust storm evolvement during historical period was primarily analyzed in this article. The result shows that the sand-dust storms began to expand eastwardly from Han Dynasty. It had spread all over the northern China during the Ming and the Qing dynasty. This change was correlative with the climate change, but the northward shift of political and economic center and irrational grassland reclamation are the essential reasons.

Key words: sand-dust storm, historical period, human activity
