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 1960s to the 21 st century.
