英文摘要Recently, climate simulations accompanied by sporadic geologic records have shed new light on the early origin of the Asian monsoon system. Here, we reconstructed the humidity gradient and vegetation distribution over eastern Asia, spanning the Eocene-Oligocene epoch, based on 52 well-dated palynological records (obtained at 50 sites) published over the past 40 years. On the paleogeographic map, the modern-like east-west humidity gradient was established at least in the Middle Eocene, it prevailed throughout the Oligocene, and dominated during the Neogene. This pattern was further supported by the pollen-based biome results: forests dominated the eastern part of the study area, while treeless steppes and deserts occupied the continental interior. Even in the cooler early Oligocene, the eastern forest shrank but did not disappear, allowing a similar pattern to persist. Due to the water vapour of eastern Asia being sourced mainly from the Pacific Ocean to the east and transported by the summer monsoon, we speculate that the Asian monsoon had already emerged by the Middle Eocene. The cooling event at the Eocene-Oligocene transition (EOT) weakened this monsoon.
