摘要： 火卫二（Deimos）是火星自然卫星之一，研究人员利用火星探测器对其地形地貌开展了大量研究。首先对火卫二的基本参数及起源假说进行了介绍，进而全面梳理了与火卫二相关的航天探测活动，重点对地形地貌探测活动进行了详细介绍，并对围绕火卫二地形地貌的研究成果进行了归纳分析，结果表明火卫二表面分布有撞击坑、风化层、明亮的反射物质及块状物，并存在物质移动。最后针对火卫二探测不全面的情况，给出了中国关于火卫二探测的建议。

Abstract: Deimos is one of the two natural satellites of Mars, and researchers used Mars probes to observe Deimos and did research on topography and geomorphology of Deimos. In this paper, the basic information and the origin hypotheses of Deimos are described, and then a detailed description for each observation activity is made one by one, finally the research results about Deimos are analyzed. The conclusions show that there are craters, regolith, bright albedo markings and blocks on Deimos surface and the surface matter has downslope movement. According to the situation that there is not enough exploration about Deimos, some advices for future exploration are given.

Key words: Deimos, origin hypothesis, topography, geomorphology, craters, regolith
