晚渐新世—早中新世青藏高原隆升与东亚季风演化

摘要/Abstract

摘要： 晚渐新世—早中新世是东亚环境格局从行星风系气候格局向类似于现今的季风气候格局转变的关键时期。最新的地质证据表明，高原东北部在25～22 Ma发生了显著的构造抬升，与亚洲内陆荒漠和东亚季风系统起源的时间基本一致，支持气候模拟所揭示的东亚季风起源与青藏高原北部隆升的密切关系。

Abstract: The East Asian climate were transformed from a zonal pattern to a monsoon-dominated pattern from the latest Oligocene to the earliest Miocene (25~22 Ma). Recent geological evidence indicates significant uplift of the NE Tibetan Plateau during this interval, timely coupled with the initiation of East Asian monsoon system and onset of desertification in the Asian interior, thus supporting the modeling results that the initiation of East Asian monsoon system is mainly related to the uplift of northern Tibetan Plateau.
