Nowadays,it is urgent to improve forecast level of snowfall,to study regional climate change,to utilize scientifically water resources and to protect ecological environment in east Hexi Corridor. Using daily snow data from five meteorological stations in east Hexi Corridor during 1960-2016,temporal and spatial variations of snowy days in this region were analyzed with climatic statistics method. The results showed that temporal and spatial variations of snowy days had been decreased from southwest to northeast because of the effect of altitude, topography and weather system. Except for Liangzhou,annual and decadal snowy days had decreased,expecially in Tianzhu. Time series of annual snowy days had a six to eight years quasi-periodic variation. Temporally, monthly variation of snowy days had been rather consistent; snowy days mainly appeared from January to April and from October to December,with a peak in March,and winter was the primary snow season. Annual anomalism of snowy days was consistent every where,with an occurrence probability of 68. 4% ~ 73. 7% normally, and declining to both ends in turn. Less snowy days had a high percentage of snowy days in east Hexi Corridor, with a occurrence probability of 78. 6% ~ 93. 5% and decreasing rapidly with magnitude. Less snowy days of 0. 0 mm had decreased significantly and had negatively contributed to total snowy days; less snowy days of ≥0. 1 mm and middle snowy days had increased mostly and positively contributed to total snowy days; heavy snow days had weakly decreased mostly and had negatively contributed to total snowy days.
