Abstract: Shihezi area is arid oasis, development of local irrigation and livestock depended on snow melt water largely. Therefore, the study of snow cover climate change had great significance of agricultural production and ecological environment in Shihezi. Using relevant information of annual snow cover days, annual maximum snowy depth and annual beginning and ending snow cover days during 1954-2011, the author analyzed climatic features of snow cover days, annual snow cover days, annual beginning and ending snow cover days, annual maximum snowy depth and its impact factors in Shihezi, applicated statistical methods of linear trend analysis, Morlet wavelet analysis and mathematical backward multiple linear regression. The results showed that: annual snow cover days and annual ending snow cover days showed a downward trend, the maximum snowy depth and annual beginning snow cover days showed an upward trend in Shihezi for past 58 years; annual average snow cover days was 109.4 d in Shihezi, the most average monthly snow cover days was in January; annual snow cover days existed quasi-15-year decadal cycle in Shihezi for past 58 years; the most relationship of the average monthly snow cover days was average monthly temperature and average monthly 0 cm ground temperature.
