Abstract The causes of terrace formation in active orogenic belts have long been studied. Here, we present a synthesis of 147 available papers on the ages of Quaternary terraces within the Tibetan Plateau and along the surrounding orogenic belts. More than 1500 ages were collected to establish a database for exploring the causes of fluvial terrace formation. Because the age data were collected from different settings, ages younger than 200 ka were grouped into three regional climate systems: the westerlies, Indian summer monsoon, and East Asian summer monsoon. We further examined the relationship between terrace formation and climate change, as well as the contribution of tectonic uplift. Our results indicate that the intervals of fluvial terrace formation are synchronous with transitions in global climate from cooler to warmer conditions (stadials to interstadials). We propose that the formation of fluvial terraces across the Tibetan Plateau has been controlled mainly by cyclical climate changes, although there is not a one-to-one correspondence.

自 200 kya 以来气候驱动的青藏高原河流阶地形成：综述

摘要 活动造山带阶地形成的成因研究已久。在这里，我们综合了 147 篇关于青藏高原及其周围造山带第四纪阶地年龄的论文。收集了1500多个年龄，建立了一个探索河流阶地形成原因的数据库。由于年龄数据是从不同环境收集的，年龄小于 200 ka 的年龄被分为三个区域气候系统：西风、印度夏季风和东亚夏季风。我们进一步研究了阶地形成与气候变化之间的关系，以及构造隆升的贡献。我们的结果表明，河流阶地形成的间隔与全球气候从较冷到温暖的条件（stadials 到 interstadials）的转变同步。我们认为青藏高原河流阶地的形成主要受周期性气候变化的控制，尽管没有一一对应。
