Abstract: The paper aims to clearly understand the characteristics of temporal and spatial variation of snow cover in Dalian Area under global climate warming, and serve agricultural production. Based on observation data of snow cover days from 1960 to 2013, the author analyzed temporal and spatial variation of snow cover days, first and last snow cover date in Dalian Region. The results showed that: monthly mean snow cover days had a temporal variation of single peak type, mainly concentrated in January. In recent 54 years, there were more snow cover days from the late 1960’s to the early 1970’s, and abnormal minimum snow cover days in the middle of 1990’s. The temporal variation of snow cover days was well consistent with the variation of winter temperature; both of them had the abrupt change in 1998. Spatial variation of snow cover days was similar to the spatial variation of temperature, but was not consistent with the snowfall frequency distribution.
