| 摘 要： | 沙尘暴(sand—duststorm)系指强风把地表大量沙尘卷入到空中，使空气特别浑浊，水平能见度低于1000m的灾害性天气现象。是1种危害性极大的灾害性天气。它的发生和发展是加速土地荒漠化的重要过程，又是土地荒漠化发展到一定程度的具体体现。沙尘暴尘源物质的形成及分布是形成沙尘暴必不可少的物质条件。本文在查阅分析了大量关于沙尘暴研究等文献的基础上，从沙尘暴尘源形成因素、尘源种类及分布等方面，对沙尘暴尘源的研究进行了简要的总结，反映沙尘暴尘源方面的研究进展。 |
| 关 键 词： | 沙尘暴 沙尘源 成因 区域分布 |

| Abstract: | Sand-dust storms are a disastrous weather generated by strong winds, which carry a large amount of sand and dust from the surface of the earth into the sky. The level visibility is below 1000 meters when a sand-dust storm takes place. Sand-dust storms increase the process of the desertification of the farming land and is also a concrete symbol of the degrees of the desertification of the farming land. The origin of the sand and dust in the sand-dust storm forms the indispensable material condition.The factors of the formation of the sand-dust storms, the sorts and the distribution of the sand and dust, the origin of the sand and dust and the latest study progress were summarized on the basis of the analysis of the recent documents in this field. |
| Keywords: | sand-dust storm the origin of the sand-dust formation distribution |
