摘　　要：分析了高原地面加热场强度距平指数与四川盆地伏旱及主汛期降水的联系。结果表明，高原前期加热强度同四川盆汛期降水和伏旱程度密切相关。把这些关系引入汛期降水预测模型对提高短期气候预测能力有一定积极意义。The relation between surface heating strength over Tibet plateau and the precipitation of main flood season and late summer drought in Sichuan province is analysed.The results show that:(1)There are negative correlations between the plateau heating strength in last early summer and the strength of late summer drought in those years.(2)There are negative correlations between the plateau heating strength in winter and the precipitation of main flood season in the western and middle part of Sichuan Basin.(3)There are positive correlations between the plateau heating strength in June and the precipitation in the west of Sichuan province in August.These correlation can be led to forecasting models for precipitation of flood season.
