中国南部，特别是云南，在新近纪喜马拉雅山脉隆升的作用下，经历了强烈的构造活动，导致古地理的快速变化。前人的研究表明，南中国至少在中新世早期就受到了亚洲季风的影响。然而，人们对中新世季风系统的强度还没有很好的了解。本文对中国南部16个地点的63个化石植物群进行了整理和评价，以获得植物群组成、地层时代和沉积学等方面的信息，并在此基础上，用共存的方法对选定的大型和微型植物群进行了分析，以获得定量的古气候数据。地图上的气候可视化结果表明，中国南部地区在中新世具有明显的空间分异。气温和降水的季节性较高分别出现在中国南部的北部和南部。中新世，中国南部和欧洲的大部分地区既温暖又潮湿。欧亚大陆中部可能是一个干旱的中心，逐渐向西和向东扩散。我们的数据提供了有关中国南部中新世气候模式的信息，以及这些模式在整个中新世的演化过程，对于揭示和理解全球降温和构造抬升的气候信号也是至关重要的。
Southern China, especially Yunnan, has undergone high tectonic activity caused by the uplift of Himalayan Mountains during the Neogene, which led to a fast changing palaeogeography. Previous study shows that Southern China has been influenced by the Asian Monsoon since at least the Early Miocene. However, it is yet not well understood how intense the Miocene monsoon system was. In the present study, 63 fossil floras of 16 localities from Southern China are compiled and evaluated for obtaining available information concerning floristic composition, stratigraphic age, sedimentology, etc. Based on such reliable information, selected mega- and micro-floras have been analysed with the coexistence approach to obtain quantitative palaeoclimate data. Visualization of climate results in maps shows a distinct spatial differentiation in Southern China during the Miocene. Higher seasonalities of temperature and precipitation occur in the north and south parts of Southern China, respectively. During the Miocene, most regions of Southern China and Europe were both warm and humid. Central Eurasia was likely to be an arid center, which gradually spread westward and eastward. Our data provide information about Miocene climate patterns in Southern China and about the evolution of these patterns throughout the Miocene, and is also crucial to unravel and understand the climatic signals of global cooling and tectonic uplift.
