利用 1953—2014年青海省共和气象站逐日平均气温资料,采用5 d滑动平均法统计分析稳定通过≥0℃和≥3℃的初终日期,并分别求算初、终日期间持续日数和初、终日期间≥0℃、≥3℃的积温.结果表明,各界限温度初日呈现提前趋势,终日呈现推后趋势;各界限温度间的持续日数和积温均呈现增多趋势.

The data of ground-ob-served diurnal air temperature were used to compute the initial and final dates of≥0℃,≥3℃ from 1953 to 2014,as well as the duration days and the accumulat-ed temperature between beginning dates and ending dates, respectively,by using the method of 5 days running mean in Gonghe, Qinghai Province. The results showed that there were obviously earlier beginning in the initial dates and later ending in the final dates appeared in all of the critical temperatures, accompanied with this tread ,it showed a significantly increasing tread in the duration days and accumulated temperature.
