| 摘 要： | 重点研究了20世纪以来云南4次强震活跃期的酝酿及启动过程，发现地壳内构造能量的多年加速积累是形成云南强震活跃期的必要条件，而月球的运行位置及地表涝旱振荡的加剧又进一步调控着活跃期的时间。在此基础上，建立了一套预测云南强震活跃期的定量判据，并应用于对云南地区下一强震活跃期的实际监视中。

| Abstract: | The seismic activity in Yunnan is characterized by the alternation of active and quiet periods. By studying the preparation and initiation processes of four active periods of strong earthquakes in Yunnan since the 20th century, it is found that the continuous accumulation of structural strain in the crust is the essential condition to form the active period of strong earthquakes in Yunnan, the position of the moon and the sharp change between drought and waterlogging further regulate the occurrence time of strong seismic active period. According to this, we built a set of quantification index to forecast future active period of strong erthquakes in Yunnan. |

| Keywords: | strong earthquake active period quiet period obliquity of the lunar orbit draught and waterlogging change |
