摘要: 利用(1951~2000年)气温、降水资料分析我国北方地区沙尘暴的演变趋势,探讨沙尘 暴的机理和形成机制,重点研究了气候异常事件对今春我国北方沙尘天气频发的可能影响。指 出,为加深对沙尘暴的认识并减轻其对社会经济可持续发展的影响、应加强对沙尘暴形成机理 的科学研究建立沙尘暴监测、预警系统,同时对荒漠化土地进行科学的治理。

Abstract: s: The evolvement tendency of dust devil in North China was analyzed and the mechanism for the formation of dust devil was discussed in this article. In 2000 spring, the dust weather occurred frequently in North China. The impacts of climate abnormality on that was studied by using the data of temperature and precipitation from 1951 to 2000. To mitigate the negative influence of dust devil on soot--economic sustainable development, it is important to carry on scientific research on dust devil, and develop a system to monitor and predict dust devil. It is concluded that the damage of dust devil can be mitigated by taking some steps to prevent the worsen conditions of desert area through scientific methods.

Key words: dust devil, climate abnormality, mitigating countermeasure
