摘　　要：本文应用谱分析方法,讨论了我国年降水量的振荡及其与东太平洋海温的关系,得出我国年降水量在四川、贵州和黄淮地区具有5—7年的振荡,东北地区具有3—4年的振荡,黄河中下游、长江中下游及华南沿海地区具有2—3年的振荡同时与赤道东太平洋海温有较好的耦合关系。In this paper , the oscillations of the annual rainfalls in China and their relations with the SST in the equatorial eastern Pacific are investigated. It is found that there are 5-7 years oscillation in Sichuan, Guizhou and Huang-Huai regions. 3-4 years oscillation in the north-eastern China and 2-3 years oscillation in northern China, the middle-lower reaches of the Yangtze River Valley and the coastal regions of the southern China. The 2-3 years oscillations are coupled well with the SST in the equatorial eastern Pacific.
