从地气耦合观点讨论洪涝灾害

Discussion on Flood in the Light of Earth-Atmosphere Coupling

洪涝主要是气象因素决定的，但特大地震断层错动形成的引张区内地壳释放出携热水气和温室气体与大气环流相配合可能会增加降雨强度。该文讨论了20世纪至2009年4个国内8．0～8．5级地震断层错动引张区的洪涝实例；还讨论了苏门达腊-安达曼8．9级地震引张区对应我国西江特大洪水的实例。

Flood disasters are mainly caused by meteorological factors. It is possible that the superposition of vapor and green house gas flowing out from extension ground formed by dislocation of catastrophic earthquake on atmospheric circulation may increase intensity of precipitation. Four floods in the extension quarter formed by four catastrophic earthquakes Ms 8.0 - 8：5 occurring in the period from last century up to date in China were discussed. Besides, an example of a big flood in Xijiang River in the extension quarter of Sumatra Andaman earthquake MS. 9 is discussed.
