This paper presents the results of mapping inherited cold‐climate landforms and deposits at the Muchów Hills site in the Sudetes, Central Europe (51°N). Bedrock supporting the upper slopes is basalt, with well‐developed columnar jointing, and local relief is of the order of 100 m, whereas the middle and lower slopes are underlain by glacigenic deposits. Characteristic cold‐climate landforms include rock cliffs, talus aprons, mid‐slope benches, solifluction sheets and lobes, and are integrated into sediment transport systems linking bedrock elevations with the adjacent plain. Ground identification of these features may be ambiguous, but the interpretation of high‐resolution LiDAR Digital Terrain Modeling data helped to provide a comprehensive spatial picture. Reasons for partial remodeling of inherited periglacial landforms in the Muchów Hills include biogeomorphological activity throughout the Holocene, mainly tree uprooting and resultant regolith mixing.

中欧苏德特州玄武岩山的继承冰缘地貌:来自LiDAR辅助地形图的见解

本文介绍了对中欧苏德特斯(51°N)MuchówHills遗址继承的冷气候地貌和沉积物进行测绘的结果。支撑上斜坡的基岩是玄武岩,柱状节理发育良好,局部起伏约为100 m,而中下斜坡则由成冰作用沉积。寒冷气候的地貌特征包括岩石峭壁,距骨围裙,中坡台阶,固溶薄片和裂片,并被整合到将基岩标高与相邻平原相连的沉积物输送系统中。这些特征的地面识别可能不明确,但是高分辨率LiDAR数字地形建模数据的解释有助于提供全面的空间图景。
