摘　　要：稀有气体与CO2、CH4、N2等气体及其同位素的结合研究是近年迅速发展的研究体系。本文综述了2种体系的同位素指标以及CO2/3He、CH4/3He、N2/Ar等比值指标在地质领域的研究与应用情况,简述了N2、O2等气体与稀有气体在探索地球大气演化模式方面的概况。The integrated study of noble gases and gases such as CO2, CH4 and N2 and their isotopes is an effective method developed rapidly in recent years. This paper reviews the study and application of the isotope indicators of two systems and the indicators of ratios such as CO2/3He, CH4/3He and N2/Ar in the geological field and gives a brief account of the application of gases such as CO2, CH4 and N2 and noble gases in probing the model of evolution of the Earth's atmosphere.
