Abstract: In order to analyze change process of regional temperature response to global climate change, daily maximum, minimum and average temperature data of 6 meteorological stations from 1959 to 2011 were used to analyze the change characteristics of extreme temperature in loess plateau area of northern Shaanxi Province. Results showed that: (1) for the change trend, warm indexes in the region, like extreme maximum temperature, length of growing season, warm night days and warm day days, showed a significant increase trend, while cold indexes in the region, like frost days, freezing days, cold night days and cold day days, showed a significantly decreasing trend, the trend of extreme temperature index was consistent with the national trend; (2) in spatial distribution, the maximum and minimum value of extreme temperature indexes distribution were more concentrated in Wuqi and Yulin station, which reflected that the north and west regions of loess plateau area in northern Shaanxi Province were sensitive to climate change; (3) the decrease mutation of the cold indexes in the region like freezing days, cold night days and cold day days occurred in the 1980s, while the increase mutation of the warm indexes in the region like extreme maximum temperature, length of growing season, warm night days and warm day days occurred in the 1990s.
