Abstract: The paper aims to provide a scientific basis for rationally utilizing climate resource and distribution of agricultural production. Based on the daily temperature data of Guinan Meteorological Bureau in Qinghai during 1961—2017,the spatiotemporal changes of the first date, final date,duration,and accumulated temperature were analyzed when the temperature reached 10℃ or higher, using the methods of linear regression,accumulative anomaly,T-test.The results showed that accumulated temperature,duration,first date, all showed a significant increasing tendency, and final date showed a insignificant increasing tendency during 1961—2017,with the rates of 3.2 d.10a-1、4.8 d.10a-1和65.6 (℃.d).10a-1,and the final date with the rates of 1.1 d.10a-1.The beginning date with the temperature stability through 10℃ had a advanced climate abrupt in 1994,the ending date with the temperature stability through 10℃ had a delay climate abrupt in 1988,the durations, accumulated temperature had a increased climate abrupt in 1993.
