摘　　要：选取四川盆地20个地面气象站1951～2000年平均气温和降水的逐日观测资料,利用最小二乘法计算气候倾向率和年代际变化的方法,对近50年来四川盆地气候的年际和年代际变化进行了诊断分析,以期对未来的气候估计和预测有一定的参考价值。Based on the daily mean air temperatures and precipitation data of 20 stations in Sichuan Basin from 1951 - 2000 , characteristics of inter-annual and inter-decadal climate variations in Sichuan Basin were statistically investigated by calculating Climate tendency with least square method and temperature changes per ten years of air temperature. These results show the picture of climate in Sichuan Basin for recent 50 years and can give us some clue in forecasting the coming years＇ climate.
