Based on the daily average air temperature date obtained from 27 meteorological stations in Gansu Province during the period from 1960 to 2014,the temporal and abrupt change characteristic of accumulated temperature steadily above 0℃ and 10℃ over the recent 55 years were identified by using linear trend estimation and Mann-Kendall test,ArcGIS-based mixed interpolation was used to analyze the spatiotemporal change of accumulated temperature steadily above 0℃ and 10 ℃ in 19602014,before and after their discontinuity ascension in recent 55 years.The results show that:(1)the spatial distribution of performance of accumulated temperature steadily above 0℃ and 10℃ gradually reduce from southeast to northwest,and from the plains,valleys,to plateaus and mountain basin in Gansu Province;(2)the accumulated temperature steadily above 0℃ and 10℃ increased significantly along with climate warming,and the regression coefficient of accumulated temperature was 66℃/decade and 64.75℃/decade,these changes experienced significant mutation in 1998whereby the rate of change before and after accumulated temperature steadily above 0℃ and 10℃ was different in different areas that increases with increase of latitude from southwest to northeast;(3)the change of climate zones expanded to high altitude and latitude along with climate warming,North Subtropical Zone and Temperate Zone gradually expanded,and Plateau Climate Zone showed the decreasing trend.
