Abstract: In order to master the characteristics of temperature variation of Yushe county, providing theoretical basis for carrying out scientific research of the poverty alleviation by ecological agriculture project, based on the temperature data of Yushe county from 1961 to 2010, the variation trend and characteristics of temperatures change in Yushe county were analyzed by adopting such statistical methods as linear tendency estimation, correlation coefficient analysis, moving average and Mann-Kendall test. The results showed that: The temperature had a rising tendency in recent 50 years, the tendency rate of temperature change was 0.08℃/10a. The annual average maximum temperatures, winter average temperature, annual extreme maximum temperatures and spring average temperature were in the increasing trend, and their tendency rate are 0.30℃/10a, 0.28℃/10a, 0.21℃/10a and 0.12℃/10a, respectively, while the annual extreme minimum temperatures, summer average temperature, annual average minimum temperature and autumn average temperature were in the decreasing trend, and their tendency rate were -0.30℃/10a, -0.04℃/10a, -0.03℃/10a and -0.02℃/10a. The period of evident rising was the 1990s, and the cooling trend was in the 1980s, annual average daily range of temperature presented increasing trend, and reached to the maximum in the 1990s. The largest contribution to the climate warming was rising of daytime temperature in winter and spring, and the temperature had an evident warming mutation in the middle-late 1980s to the late 1990s.
