摘要

[目的]揭示新疆、内蒙古和甘肃西北3省（区）风雪流发生的可能性，为风雪灾害防治提供理论依据。[方法]利用1981—2010年3省（区）130个区站地面气象资料，划分风雪流发生可能性等级。[结果]①研究区65.4%的地区有发生风雪流灾害的可能性，其中16.9%的地区发生风雪流可能性的等级较高；②研究区风雪流灾害最严重的月份为3和12月，少数地区受地形影响有所差异；③研究区30 a间气象数据在一定范围内波动，风雪灾害发生可能性没有减弱趋势。[结论]西北3省（区）需重视风雪灾害防治，尤其是3和12月应重点防护；同时要加强生态修复工作，降低风雪灾害。

Abstract

[Objective] To reveal the probability of snow flow in the three northwestern provinces(Xinjiang

Inner Mongolia and Gansu)

in order to provide a theoretical basis for disaster prevention and control of snowstorm disasters.[Methods] We used the ground meteorological data from 130 district stations from 1981 to 2010

to classify the probability level of snow flow.[Results] ①In the study area

65.4% of the regions have the probability for snowstorm disaster

of which 16.9% had a higher level probability for snowstorm disaster. ② The most severe months of snowstorm disaster were March and December

and few areas were affected by terrain. ③ The meteorological data of the study area fluctuated within a certain period during the past 30 years

but the probability of snowstorm disasters was not decreased.[Conclusion] The three provinces in Northwest China should pay attention to the prevention and control of snowstorm disasters

especially in March and December. Meanwhile

ecological restoration should be strengthened to reduce the snowstorm disasters.
