摘　　要：天体生物学作为与深空探测相结合的交叉学科,旨在从地球极端环境类比、古代生命载体信息发掘和模拟等方面揭示地外行星体是否适合生命生存和繁衍,其中适宜的环境条件是评价所有天体是否宜居的重要条件。近年来在月球和火星等行星表面发现了大量由火山熔岩流形成的熔岩管道,这些巨型管状地下空间具有稳定的温度和防辐射等环境条件,为生物在地外星体上的生存提供了潜在的庇护场所。基于地球熔岩管道的天体生物学的类比研究可以为探索地外生命痕迹提供重要线索,本文综述了现阶段地球熔岩管道内微生物的研究进展、微生物痕量气体代谢在天体生物学研究中的潜力及天体生物学的研究进展,旨在为后续开展地球及地外熔岩管道的天体生物学研究提供思路。As an interdisciplinary subject combined with deep space exploration,astrobiology studies the habitability of extraterrestrial planets by the analogical study of the extreme environments on Earth,the exploration of carrier information of ancient life,and simulation.Notably,suitable environmental conditions are crucial for evaluating the habitability of planets.Recently,a large number of lava landforms suspected of lava tubes have been found on the Moon and planets such as Mars.These giant tube-shaped underground spaces may provide shelters for life to survive in consideration of the relative stable temperature inside and the function of radiation protection.Therefore,the analogical studies based on lava tubes on Earth can provide fundamental clues for exploring the traces of extraterrestrial life.Here,we review the microbial studies about the lava tubes on Earth,the implications of microbial metabolism of trace gas for astrobiology,and the recent progress in astrobiology,aiming to provide ideas for astrobiological research on lava tubes on Earth and other planets.
