To understand the extreme climate characteristics of Sichuan Basin,by using methods of linear regression,inverse distance weighted interpolation(IDW),the extreme climate events such as high temperature and heavy rain were analyzed in East Sichuan Basin.The results showed that:(1)the temperature warming rate was 0.10℃/decade in the last 54years in Sichuan Basin;the precipitation presented a decreasing trend at the rate of 21.63mm/decade,climate warming-drying trend was apparent.(2)the annual average high temperature days presented an increased trend by 0.95d/decade in East Sichuan Basin;the annual average high temperature days had an obvious regional differences,the annual high temperature days all presented an increasing trend in East Sichuan Basin.(3)the average rainstorm days presented the decreasing trend at the rate of 0.03d/decade;Wanyuan and Ya′an were the high value centers of rainstorm days;the rainstorm days showed an increasing trend in the east of GuangyuanLangzhongSuining,most areas showed a decreasing trend in the west of Guangyuan-Langzhong-Suining.(4)in the background of warming-drying climate,the frequency of high temperature had increased by 38.81%,strength exacerbated 1.18%;rainstorm days decreased by 0.78%in frequency,but increased by 1.66%in strength.
