摘　　要：通过对我国东南象限冬、春季雨带的相关分析，发现当冬、春季之间地气形势稳定时，约有68％的春雨带位于冬雨带南方50-300km的范围内，此统计结果可作为预报春雨的指标；当冬季地气形势出现“双跳型”时，冬、春季之间的雨带可相距500km以上，此时冬、春季的地震时空变化有可能作为春雨位置的预报指标。By analyzing the correlation between the rain belts in winter and spring, the results show that in the southeast quadrant of China, when the earth-atmosphere position is stabilization in winter and spring, the frequency that the rain belt in spring about 73% lies to the south of the rain belt in winter and the distance is about 50-300 km, and the result may＇be index for predicting rain in spring. At the other hand, when the earth- atmosphere position is instability, the distance between the rain belt in winter and spring may be over 500 km. In that case, the earthquake in winter and spring may be as an index for predicting the rain in spring.
