中文摘要：

温室性气体地质处置的机理有3个：①将深部含水地层作为容器封闭CO2；②含水（油）介质，印岩石矿物与CO2发生化学反应而消耗掉CO2，使CO2长期安全保存于地下介质中；③在低渗透含水层中，CO2的运移与滞留时间较长，属于水力学控制CO2的机制。尽管CO2的地质处置存在费用和安全稳定性问题，但国际上已开展的研究表明，地质处置温室性气体是人类积极解决全球环境问题极具前景的方法之一。

英文摘要：

The recent advances of geological sequestration of greenhouse gases are reviewed in this paper. There are three kinds of mechanism in geological sequestration. The first is that deep aquifer is regarded as a container for CO2, and the second is the minerals in deep aquifer will react with CO2 and then trap it, so COz will remain stably underground. And thirdly, in low permeable aquifer, the transport of CO2 is slow whose stay is controlled by hydraulics. The research by international experts shows that geological disposal of CO2 is one of the promising methods for solving global climate problem although there are still problems about costs, safety and stability.
