摘要
本文利用1961—2000年塔里木盆地22个气象站的气象实测资料,分析了近40年塔里木盆地沙尘暴天气的时空分布特征。结果表明:塔里木盆地沙尘暴日数从60年代至90年代,总的趋势是在波动中下降的,高发年代多在20世纪70年代和80年代,90年代沙尘暴的发生明显减少;塔里木盆地沙尘暴天气发生的日数有2个明显的高发区,即以喀什、阿图什的塔东地区和以策勒、和田为中心的塔南地区;塔里木盆地沙尘暴天气对于新疆地区气候的变化响应显著,与平原区的降水和温度相关性较好。
Based on the available high-quality surface-meteorlogical observation data from 22 stations in Trim basin from 1961 to 2000,investigation has been conducted for the temporal and spatial distribution characteristics, especially for interdecadal change and long-term trend of sandstorm in Trim basin in recent 40 years. According to the analyses on number of sandstorm＇s days, the following results are noted： On the whole of Tarim basin, annual frequency of sandstorm reduced from 1961 to 2000;The most frequently occurred region of sandstorm is in the east and south Tarim basin; The climate shifts to warm humid have produced a certain impact for sandstorms.
