Using initial ice date and end ice date,as well as soil and air temperature data,from five meteorological stations in east of the Hexi Corridor during 1961 -2015,temporal and spatial change characteristics of initial ice date and end ice date and their relation to soil,air temperatures and altitude were analyzed in this paper with modern climate diagnosis method. The results showed that,temporally,the initial ice date was earlier in mountains,followed by desert,finally in oasis and plain,and the end ice date was later in mountains,followed by desert,finally in oasis and plain,because of the influence of altitude,topography,vegetation and surface lithology. Initial ice date and end ice date had certain abnormal locally,with the probability of about 60% of normal initial ice date and end ice date. Probability of partial early year and early year of initial ice date and probability of partial late and late year of end ice date,which will cause hazard to production,were about 20%. There was a good correspondence between initial ice date and end ice date and the year with abnormal temperature. The initial ice date tended to delay and the end ice date tended to get early,the delayed magnitude was more than the early magnitude. Time series of initial ice date and end ice date had ten to twelve years and eight to ten years quasi-periodic variation,respectively. There were extremely significant correlations between initial ice date and end ice date and soil and air temperatures and altitude. The initial ice date will delay about 3.0 d and 3.5 d and the end ice date will about 4.2 d and 4.9 d ahead of time for 1 degree centigrade increase of soil and air temperature; the initial ice date will 1.8 d ahead of time and the end ice date will delay 2.5 d for every 100- m altitude increase. The end ice date was more sensitive response to climate warming and altitude increasing than the initial ice date.
