The Vo n Krmn impact crater in the Chang’E-4 landing area is located in in the Northwestern South Pole-Aitken (SPA) basin on the back of the Moon, and the analysis of its topography and compositional characteristics is essential for the landing of the probe and the exploration of the lunar surface, which plays a fundamental role in obtaining information on the geomorphology and geology of the lunar surface. In this paper, the topography of the Vo n Krmn impact crater is analyzed based on DEM, slope and terrain roughness, then the compositional characteristics of the Von Krmn impact crater are analyzed according to TiO₂ and FeO content through combining LRO LOLA data and Clementine UV-VIS data. This study is a basis for revealing the surface characteristics and structure of the Moon.

嫦娥四号着陆区的Von Krmn撞击坑位于月球背面的西北南极-艾特肯（SPA）盆地，分析其地形和成分特征对于着陆至关重要探测和月面探测，对获取月面地貌和地质信息具有基础性作用。本文基于DEM、坡度和地形粗糙度分析了Von Krmn撞击坑的地形，然后结合LRO LOLA数据和Clementine，根据TiO ₂和FeO含量分析了Von Krmn撞击坑的成分特征。紫外可见数据。这项研究是揭示月球表面特征和结构的基础。
