A multi-level classification method and schemes for lunar landforms
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,sub-morphology,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.
