In order to study the response of the climate in the Loess Plateau region to Hiatus of global change phenomenon, based on the annual and monthly data of average minimum temperature, average temperature and average maximum temperature in 114 meteorological stations of Loess Plateau and the surrounding region from 1960 to 2013, trend of temperature in the Loess Plateau were analyzed by the linear trend and Mann-Kendall trend test method. The results indicated that mean temperature had significantly increased by 0.27℃/decade from 1960 to 2013, the annual minimum temperature and maximum temperature also showed the increasing trend, the average minimum temperature rising rate(0.35℃/decade)was greater than average maximum temperature(0.297℃/decade)and average temperature(0.27℃/decade). The variability of annual average temperature and maximum temperature displayed the increasing trend from the southeast to the northwest. Temperature departure value of mean minimum temperature, mean maximum temperature, mean temperature had been larger than the previous decade since the 1960s. Variability of average temperature and minimum temperature in winter were the most significant but the maximum temperature increased obviously in autumn. There was the decreasing trend for the maximum temperature at the rate of -0.33℃/decade during the period of Hiatus(1998—2013). During the period, the decrease of temperature was caused by a significant decrease of temperature in winter, but the increasing trend of temperature was not obviously increase in summer. The mean minimum and maximum temperature decreased at the same time between 1998 and 2013. The temperature change in the Loess Plateau had the significant response to Hiatus of global change phenomenon. The regional temperature change in the Loess Plateau had proved that the decreasing trend of global temperature in 1998—2013 occurred.
