地球的脱气过程及对人类生活环境的影响

DEGASSING PROCESS OF THE EARTH AND ITS EFFECTS ON LIVING ENVIRONMENT OF MANKIND

地球是一个巨大的开放系统。地球的脱气是岩石圈与大气圈进行物质能量交换的重要形式,也对人类生活环境产生重大影响。地球的脱气场所与地质构造关系密切。大规模的脱气在空间上是不均匀分布的,在时间上是非匀速有起伏的。灾变事件往往伴随有气体异常,气体异常溢出有可能酿成灾变。监测重点地区的地球脱气过程,可为防灾减灾及研究地壳活动提供丰富信息。

The earth is a huge opening system. Crustal degassing process is an important form of exchanging mass and energy between atmosphere and lithosphere, and it has great effects on the mankind living environment. The large degassing processes are not uniform and fluctuation in spatial and temporal distribution.The gas anomalies were often occurred following the catastrophic events. The abnomal gase leaking could cause desasters. The degassing monitoring programs on some impending geocalamitous areas, might give aboundant imformation for protecting and decreasing hazards and for describing the earth crustal activity.
