摘　　要：月球地貌是其表面高低起伏的状态,月球自形成后经历了不同的内、外营力作用最终形成了现在的地貌特征。月球地貌分类是月球地貌学研究的基础,也是月球地貌制图的基础和关键科学问题。本文参考地球地貌分类体系,提出了月球地貌分类的原则与指标,综合考虑月球地貌的宏观基本形态、成因、地貌实体形态、组合形态、次级形态、坡面形态、物质组成与岩性及年代等多种分类指标,构建了月球地貌类型的多层级分类方案,包括月表高程分级、宏观形态分级、成因类型、形态类型、组合形态亚类、次级形态亚类、坡面形态亚类、物质组成亚类与地貌年代亚类九级。基于本文提出的月球地貌多层级分类方案,以嫦娥五号采样返回区为典型研究区进行月球地貌制图,建立嫦娥五号着陆区月球地貌类型数据库。月球地貌类型分类的研究可为月球地貌图编制提供基础参考,为深入理解月球地貌演化过程提供重要依据。Lunar landforms,characterized by the elevation variations on lunar surface,is a result of diverse internal and external forces acting upon it since its formation.Lunar geomorphological classification serves as the cornerstone of lunar geomorphology research and is crucial for lunar geomorphology mapping.This study draws inspiration from terrestrial geomorphological classification systems to propose a comprehensive framework for categorizing lunar landforms.We consider multiple factors,including macroscopic morphology,genesis,morphological characteristics,combinational morphology,submorphology,slope morphology,material composition,and age.Based on these indicators,the paper constructs a multi-level classification scheme for lunar landform types,encompassing nine levels.To demonstrate the applicability of this multi-level classification,we conducted a case study in the Chang'e-5 sample return area.We generated a detailed geomorphological map and established a corresponding database of lunar landform types for the landing area.This research provides a foundational framework for lunar geomorphological mapping and offers valuable insights into the evolutionary processes that have shaped the lunar surface.The proposed classification scheme can serve as a reference for future lunar exploration missions and contribute to a deeper understanding of the evolutionary process of lunar landforms.
