摘要: 在月球探测及科学研究过程中,对月表形貌特征的认识和分析是月球探测计划的关键任务之一,有助于理解和揭示月球的形态特征及空间分异规律,对于分析月球岩石构造、估算月表年龄、反演月壤厚度、恢复月球的起源和演化历史等都具有重要意义。从月表形貌特征的塑造及表达、宏观特征的分析与定量刻画、月表撞击坑的识别与分类及空间分异特征等几方面进行了归纳和分析,提出了未来月表形貌的研究方向,包括全月球形貌特征的多级分区划分、撞击坑类型的划分、全月球撞击坑空间分异特征及规律的研究、基于撞击坑空间分布探讨月球演化、基于形貌特征的比较行星学研究等。

Abstract: The study on lunar topography and geomorphology is one of the key tasks of the lunar exploration program, which are essential to expanding understanding of lunar surface. The lunar topography research also had a profound effect on other studies such as the lunar rock formations, the estimation of relative lunar age, the correction of landing sites of detectors, the recovery of the thickness of lunar soil, and the evolution history of the moon. This paper reviewed the research of lunar surface morphology from the following four aspects: (1) the formation and visualization of lunar topography and geomorphology; (2) the macroscopic analysis and quantitative characterization of lunar topography and geomorphology; (3) the detection, classification and spatial analysis of lunar impact craters; (4) the deduction of lunar relative age based on lunar impact craters. Among the above mentioned four aspects, the emphasis was been placed on the research of lunar impact craters. Finally, we discussed the development of lunar topography and geomorphology. In the future, the complete lunar impact crater database, including multi index, such as spatial position, morphology, shape, size and ray etc. will be built; methods on how to distinguish main crater and secondary craters need to be strengthened, and thus an expression paradigm for morphological characteristics of impact craters also need to be built to understand and estimate their evolutionary history. Based on multi-sources RS and DEM data, a topographic regionalization map needs to be finished by means of many topographic index and imagery characteristics. Based on the database, the spatial distribution of lunar crater, the lunar evolution and the study of comparative planetology based on lunar topography and geomorphology will be the hot point to be researched.
