摘　　要：利用1960-2014年新疆88个气象台站积雪观测资料,分析了新疆积雪深度和积雪日数的变化趋势,揭示了新疆气象雪灾的时空分布特征。结果表明:(1)新疆积雪深度最大的区域是阿勒泰地区的东北部,而积雪日数最长的区域则出现在伊犁与天山中段,天山南麓个别站点有较大的积雪深度和持续的积雪日数。(2)新疆雪灾易发区主要在阿勒泰地区、伊犁地区和博州地区、塔城地区的东部和昌吉州的西部。南疆雪灾易发区域较少,主要出现在天山南麓的个别区域。(3)新疆气象雪灾年际及年代际变化总体变化趋势十分平缓,北疆地区发生频次平均为49次/10年,南疆地区为6次/10年。Based on the meteorological datum from 1961-2014 recorded by 88 weather stations in the area of Xinjiang,the trends of the number of days with snow cover of 0 cm depth,the seasonal maximum snow cove depth are analyzed,the spatial and temporal characteristics of snow disaster are revealed.The results show that：（1） The maximum snow cove depth appear in the northeast of Altai,and the longest snow cover days occur in the region of Yili and the middle of Tianshan Mountains, several meteorological stations in the south of Tianshan Mountains owe higher snow cove depth and snow cove days also.（2）The snow disasters has befell mainly in the region of Altai,Yi-li,Bozhou, east of Tacheng and west of Changji.It happens rarely in the south of Xinjang,except a few of stations which is in the south side of Tianshan Mountains.（3） The interannual and decadal characteristics of snow disaster, their trend are very gentle overall,at intervals of 10 years the averge frequency is 49 times in northern Xinjiang,6 times in southern Xinjiang.
