【摘要】：为了探讨中国长时间尺度湖泊时空演变规律和潜在的驱动机制,本文在柯本气候分区和中国季风—非季风区的划分基础上,对中国34个有明确数据的典型湖泊运行CCSM 3.0气候模拟系统和水量能量平衡模型模拟其水位变化,同时利用NCEP/NCAR再分析资料对中国按水汽输送划分的季风区进行验证。结果表明,末次盛冰期以来中国湖泊演化主要受千年尺度大气环流的驱动影响,在各个柯本气候区内没有明显的规律性。末次盛冰期以来,在季风区中国湖泊演化主要有早中全新世湖泊水位相对较高以及末次盛冰期和早全新世湖泊水位均较高2种演变规律;在东亚干旱区主要有中晚全新世期间湖泊水位相对较高以及末次盛冰期和中全新世湖泊水位均较高2种演变规律。本文为中国过去气候变化及湖泊演化机制研究提供新的证据,同时为人类全面认识末次盛冰期以来湖泊水位变化提供了新的视角。
[Abstract]:In order to study the temporal and spatial evolution law and potential driving mechanism of long-scale lakes in China, this paper is based on the Corben climate division and the division of monsoon and non-monsoon regions in China. The CCSM 3.0 climate simulation system and the water and energy balance model were used to simulate the water level change of 34 typical lakes in China. The monsoon region divided by water vapor transport in China was verified by NCEP/NCAR reanalysis data. The results show that the evolution of lakes in China since the last glacial peak is mainly driven by the millennial atmospheric circulation, and there is no obvious regularity in each Cobain climate region. Since the last glacial peak, the evolution of Chinese lakes in the monsoon region is characterized by the relatively high lake water level in the early Miocene and the higher lake water level in the last and early Holocene. In the arid region of East Asia, the lake water level is relatively high during the Middle-Late Holocene and the last glacial and the Miocene lake water levels are higher. This paper provides new evidence for the study of past climate change and lake evolution mechanism in China, and provides a new perspective for human beings to fully understand the lake water level changes since the last glacial peak.
