摘　　要：雅丹地貌是一种典型的风蚀地貌。多源遥感探测和就位探测均表明火星表面分布着大量的雅丹地貌,其形态特征和物质组成记录了火星气候环境变化的信息,是当前火星探测和研究的热点之一。本文对火星雅丹地貌的探测历史、分布、类型、几何特征、物质组成、年代学、发育过程及对古气候指示意义等方面的研究进展进行了总结,在此基础上,提出了当前火星雅丹地貌研究存在的主要问题,建议在未来研究中重点加强雅丹地貌定量化和比较行星学研究,并结合其物质组成、年代学等方面工作,探讨其发育过程与气候环境协同演化的机制,为深入认识火星雅丹地貌发育过程,了解火星古气候环境变化提供支持。Yardangs, typical aeolian landforms, have been found to be widespread on Mars. Their morphological characteristics and compositions record information on changing paleoclimate environment, which is the focus of Martian exploration and research. This paper summarizes the research progress on their exploration history, morphological and geometric features, classification and distribution, composition, chronology, formation process, and significance to paleoclimate/environment. On this basis, we highlight major questions in the research of Martian yardangs and emphasize the importance of their quantitative and comparative planetary studies. Meanwhile, data on Martian yardang composition and chronology needs to be combined to discuss the co-evolution mechanism between their formation and climate/environmental changes.
