摘要
Based on data of daily average temperature recorded by 29 meteorological observation stations in western Sichuan during 1961-2011,variation characteristics of temperature in western Sichuan in the past 50 years were analyzed. The results showed that average temperature in western Sichuan showed an increasing trend during 1961-2011,and the linear fitting growth rate of temperature was 0. 42 ℃/10 a. In the four seasons,average temperature also showed an increasing trend. Among the four seasons,temperature increased most significantly in summer and autumn,followed by winter,while temperature increase was weak in spring. During 1961-2011,average temperature in western Sichuan continued to grow from the 1960 s to the 21 stcentury.
