摘　　要：介绍了地壳流体CO2的3个主要成因:有机成因、变质成因及幔源成因,并着重讨论了CO2气体的稳定同位素13C的示踪性能;总结了由地壳释放CO2的主要方式、上升通道及其存在形态。在回顾地壳流体CO2等释放在目前地震监测、预报及相关研究中的主要研究进展的同时,指出地壳深部流体(CO2、He、CH4等)在同位素地球化学、深源流体运移与地震活动、深源流体对震源介质的影响等。此外,提出对深源流体监测不能仅限单一组分(CO2)的监测,需多种深源成分(He、Ne、Ar、H2、CH4)同时监测。Three main causes of crustal fluid CO2 which includes organic origin,metamorphic genesis and mantle origin are introduced,the tracing performance of stable isotope tracer 13 C of CO2 are discussed emphatically,and the release rule,the rising channel and the existence form of CO2 released from crust are also summarized. Based on the main research progress of the releasing of crustal fluids CO2 on seismic monitoring,earthquake prediction and other relative research,we point out the future hot fields of the research is that the isotope geochemistry of fluids,the relationship betw een migration of deep-seated fluids and seismic activity,the influence of deep-seated fluids to media of hypocenter etc.. In addition,we put forward that monitoring the deep-source fluid cannot use a single component（ CO2）,it need a variety of deep-source components（ He、Ne、Ar、H2、CH4） monitor simultaneously.
