摘　　要：确定行星表面地质事件的年龄,是了解行星的起源,地质活动历史,进而研究地球及内太阳系各行星形成及演化的重要环节。对于地月系统乃至整个内太阳系来说,月球是撞击作用记录的校准板。通过月表采样点的撞击坑密度和样品同位素年龄建立月球撞击坑年代函数,计算月球未采样区域的绝对模式年龄(AMA),该方法称为撞击坑大小-频数分布方法(CSFD)。虽然CSFD方法在行星科学领域应用广泛,但系统介绍类地行星撞击坑年代学原理及研究成果的文献相对较少。本文详细介绍了CSFD方法的研究进展和原理及将月球CSFD方法推算至类地行星撞击坑年代学方法的原理和研究成果,为系统了解类地行星CSFD方法的原理,获得更高精度的类地行星表面年龄,得到更为准确的类地行星地质历史和热演化规律提供参考。To determine ages of geologic events on planetary surfaces is an important part for understanding the origin and history of geologic activities of planets,and for further studying the formation and evolution of the Earth and planets of the inner solar system.For the Earth-Moon system and the entire inner solar system,the Moon is the calibration plate for the impact record.The absolute mode ages(AMA)of unsampled regions of the Moon are calculated by establishing the lunar crater chronology function from the crater density and isotopic ages of samples from sampling zones on the lunar surface.This method is called the Crater Size-Frequency Distribution method(CSFD).Although the CSFD method is widely applied in the planetary science,relatively few literatures for systematically introducing principles and research results of terrestrial planets have been published.In this paper,the research progress and principle of the CSFD method are introduced in detail,and the principle and research results of the extrapolated lunar CSFD method to the impact dating method of terrestrial planets are also introduced in detail.This paper provides a reference to systematically understand the principle of the CSFD method for terrestrial planets,to obtain higher accuracy for surface ages of terrestrial planets,and to obtain more accurate geological histories and thermal evolution patterns of terrestrial planets.
