许多地貌研究假定基岩地质学不是为了隔离地貌变化(例如气候或构造)的驱动因素而对景观形态进行的一级控制。然而，基础地质可能会影响山坡上土壤生产和泥沙输送的效率。我们对LiDAR数字地形模型进行了定量分析，以考察加利福尼亚州北部羽毛河流域两种不同岩性的山坡的地形形态，这两种岩性是花岗闪长岩岩体和变质火山岩。这两个地点之间被
Many geomorphic studies assume that bedrock geology is not a first-order control on landscape form in order to isolate drivers of geomorphic change (e.g., climate or tectonics). Yet underlying geology may influence the efficacy of soil production and sediment transport on hillslopes. We performed quantitative analysis of LiDAR digital terrain models to examine the topographic form of hillslopes in two distinct lithologies in the Feather River catchment in northern California, a granodiorite pluton and metamorphosed volcanics. The two sites, separated by
