摘要
在中国西部大震发生前后冬、春雨季常伴随雪灾。本文根据地气耦合原理着重探讨大震前、大震时和大震后雪害发生的机理和预测雪害的指标，由此探讨由地震活动性指标预测雪害的可能性。
The snowstorm occurrences are o ften a ccompanied at spring and winter season in the west of China before and after gre at earthquakes. The mec hanism and prediction indexes of snowstorm occurrences before and after great earthquakes were studied. Based on it the possibility of snowstorm prediction from the seismic indexes is studied.
