摘　　要：以内蒙古50个地面气象台站1981-2010年的积雪和同期气候因子资料,结合经典统计学、地统计和GIS方法,研究了内蒙古地区积雪的时空分布特征,并分析了其与气候因子的相关性。结论如下:(1)内蒙古积雪分布极不均匀,整体呈现东北多西南少。且存在2个高值区:呼伦贝尔市图里河、兴安盟阿尔山地区。(2)内蒙古积雪期主要集中在10月到翌年4月,积雪日数和积雪深度总体上呈现春后到初秋减少,秋后和初春增加的趋势。(3)内蒙古地区的积雪日数、积雪深度与气温、降水量、风速和日照时数均呈负相关,其中气温和降水量对积雪影响更为敏感。Based on the data of snow cover and climatic factors of 50 meteorological stations in Inner Mongolia from 1981 to 2010, combined with classical statistics, geostatistics and GIS method, the spatial and temporal distribution of snow cover in Inner Mongolia has been studied and its correlation with climatic factors has been analyzed. The results are as follows ： （ 1 ） There is an extremely uneven distribution of snow cover in Inner Mongolia, with more in northeast and less in southwest on the whole. And there are two high -value districts, one is Tulihe in Hulunbeier and the other is Aershan in Xing＇ an League. （2） The snow cover stage in Inner Mongolia is from October to next April. The snow cover days and depth decrease from late Spring to early Autumn and increase from late Autumn to early Spring. （3） In Inner Mongolia, there is negative correlation among the snow cover days and depth and tem- perature, precipitation, wind speed and sunshine duration, in which the temperature and precipitation have influ- enced the snow cover more sensitively.
