火星古湖泊研究的现状、问题与展望
Achievements, Issues and Prospects in Study of Martian Paleolakes

火星表面的古湖泊地貌能够反映火星古气候和古环境的特征及变化，对于研究火星是否曾经存在宜居环境具有重要意义.随着中国火星探测计划的提出和实施，详细了解火星古湖泊的研究进展尤为重要.总结了火星古湖泊的研究现状，重点阐述了当前对火星古湖泊的沉积地貌、矿物成分、形成年龄、分布特征等方面的研究进展.在综合分析前人研究成果的基础上，提出火星古湖泊研究中存在的主要问题，认为未来应着重在古湖泊的详细调查与地质填图、古湖泊的后期改造作用、其他类型古湖泊的识别分析以及火星与地球古湖泊的对比等方面开展研究.
Paleolakes on Martian surface have attracted great interests of researchers as they contain information on ancient aqueous environment of Mars and are important for the detection of habitable environment on Mars. With the implementing of Chinese Mars exploration program, it's of great significances to review the achievements in Martian paleolake study. We summarize the sedimentary geomorphology, mineral compositions, activity periods and global distribution of the paleolakes. On this basis, we discussed the unresolved questions in paleolake study and proposed that future studies should focus on the detailed investigation and geologic mapping of paleolakes, post lacustrine modification processes, identification of other paleolake types and the comparative study of Martian and terrestrial paleolakes
