中文摘要	利用1961-2010年新疆88个气象站的观测资料,运用空间自相关和热点分析方法,分析了近50a新疆沙尘暴冷热点的时空分布特征。结果显示:新疆沙尘暴具有明显的地区差异,空间分布具有较强的正空间自相关性,属于显著的空间集聚分布;冷热点空间演化格局逐渐稳定,呈现出不断缩小并集聚分布的趋势,冷点向新疆北部的博州和伊犁河谷集聚,热点位于塔克拉玛干沙漠边缘的和田及其周边地区,沙尘暴的防灾减灾工作需重点关注热点的时空变化。
英文摘要	Based on the surface observation data at 88 meteorology observatory stations in Xinjiang from 1961 to 2010,the spatially and temporally distributing characteristics of sandstorm days in Xinjiang were analyzed by traditional statistics,spatial autocorrelation and hot spot analysis. The results showed the sandstorm days had regional differences in Xinjiang. The sandstorm days in Xinjiang showed medium spatial correlation,belonging to the spatial agglomeration pattern. Evolution of the hot and cold spots of sandstorm days in Xinjiang was gradually stable and had a trend of continuous reduce and agglomeration distribution. The spatial structure of hot spots distribution had a center on Khotan in the south of the Taklimakan Desert,and the cold spots tended to be converged in the BoZhou and Ili region of North Xinjiang. The sandstorm disaster prevention and reduction in Xinjiang should focus on the temporal and spatial distribution of hot spots.
