Abstract The Qilian Shan, north eastern Tibetan Plateau, is an area of active deformation caused by convergence in the India-Eurasia collision zone. Geomorphic indices capture the landscape response to competition between tectonics and climate, reflecting the spatial distribution of erosion. We use geomorphic indices (hypsometric integral (HI), normalised channel steepness (ksn), elevation-relief ratio (ZR) and surface roughness (SR)) to identify areas of active deformation and erosion, highlight landscape variations and we interpret the results for potential tectonic and climatic drivers. High HI (> 0.15), ksn (> 100) and low ZR ( 0.15) and ksn (> 100) values in the eastern region are attributed to thrust parallel rivers in this region excavating wide valleys between the faults. The east-west precipitation variation across the Qilian Shan (>500 mm/yr to

青藏高原东北部祁连山碰撞构造地貌表现

摘要 青藏高原东北部祁连山是印欧大陆碰撞带辐合形成的活跃变形区。地貌指数捕捉景观对构造和气候竞争的反应，反映侵蚀的空间分布。我们使用地貌指数（测高积分 (HI)、归一化河道陡度 (ksn)、高程-起伏比 (ZR) 和表面粗糙度 (SR)）来识别活跃变形和侵蚀的区域，突出景观变化，并解释结果潜在的构造和气候驱动因素。东部地区的高 HI (> 0.15)、ksn (> 100) 和低 ZR ( 0.15) 和 ksn (> 100) 值归因于该地区逆冲平行河流在断层之间开挖宽谷。
