中国近五千年来山崩滑坡地裂等地质灾害事件存在着多种时间尺度的群发期。最显著的群发期出现在中国黄帝、夏桀、殷代、周代、西汉、东汉、西晋、元代、明清、清末时期。近８００起灾害事件时间序列谱分析表明，多尺度群发周期序列为１３８０，６００，２８８，１６２，１１８，７２，６１，３１，２４，２０，１５，１１年，具有可公度性和对数螺线性，并且与冰川泥石流、火山爆发、陨石坠落等周期序列相近，与地球运动周期、气候旋回、地质旋回一致。
There are many time-scale mass periods in geological disasters such as landslide and landslide in China over the past five thousand years. The most significant mass period occurred in the Yellow Emperor, Xia Zu, Yin Dai, Zhou Dynasty, Western Han Dynasty, Eastern Han Dynasty, Western Jin Dynasty, Yuan Dynasty, Ming and Qing Dynasties, the late Qing Dynasty. The spectral analysis of nearly 800 disaster events shows that the multi-scale periodic cluster is 1380, 600, 288, 162, 118, 72, 61, 31, 24, 20, 15 and 11 years Spiral, and with the glacial debris flow, volcanic eruptions, meteorite falls and other periodic sequence similar to the Earth’s movement cycle, climate cycle, the same geological cycle.
