Geomorphometric modeling is widely used in geosciences. However, geomorphometric modeling and mapping of Antarctic oases has not been performed so far. This article presents the first results of our work on geomorphometric modeling and mapping of the Larsemann Hills obtained in the frameworks of the 68th Russian Antarctic Expedition in January–April 2023. As input data, we used a fragment of the Reference Elevation Model of Antarctica (REMA). From the extracted and edited digital elevation model, we derived digital models and maps of the following 17 morphometric variables: slope, aspect, horizontal curvature, vertical curvature, mean curvature, Gaussian curvature, minimal curvature, maximal curvature, unsphericity curvature, difference curvature, vertical excess curvature, horizontal excess curvature, ring curvature, accumulation curvature, catchment area, topographic index, and stream power index. We also conducted a field geomorphometric interpretation work to provide correct physical geographic, geological, and geomorphological interpretations of morphometric maps. In the fieldwork, we carried out 54 foot routes with the total length of about 422 km. During the routes, we collected 150 rock samples for further petrological and mineralogical analyses as well as three-dimensional modeling of the samples. Derived morphometric maps can be useful for structural geological and process-oriented hydrological studies. The ultimate goal of the ongoing work is to create a large-scale geomorphometric atlas of Antarctic oases and other ice-free Antarctic territories.

地貌测量建模广泛应用于地球科学。然而，迄今为止，尚未对南极绿洲进行地貌建模和测绘。本文介绍了我们在 2023 年 1 月至 4 月第 68 次俄罗斯南极考察框架内获得的拉斯曼山地貌建模和测绘工作的初步成果。作为输入数据，我们使用了南极洲参考高程模型的片段（雷玛）。从提取和编辑的数字高程模型中，我们导出了以下 17 个形态变量的数字模型和地图：坡度、坡向、水平曲率、垂直曲率、平均曲率、高斯曲率、最小曲率、最大曲率、非球面曲率、差值曲率、垂直超曲率、水平超曲率、环曲率、累积曲率、流域面积、地形指数和水流功率指数。我们还进行了实地地貌测量解释工作，为地貌测量图提供正确的自然地理、地质和地貌解释。在实地考察中，我们进行了54条步行路线，总长度约422公里。在路线中，我们收集了 150 个岩石样本，用于进一步的岩石学和矿物学分析以及样本的三维建模。导出的形态测量图可用于构造地质和面向过程的水文研究。正在进行的工作的最终目标是创建南极绿洲和其他无冰南极地区的大型地貌图集。
