青藏高原腹地的内陆湖及其湖相沉积物能够较真实地反映气候变化特征,在高原环境变迁研究中备受中外科学家的关注.2006年8月15日~9月10日,中德联合考察小组对青藏高原东北部的冬给措纳湖一带进行了第四纪冻土、地貌和地质学考察,并对湖岸阶地做了初步的数字高程分析.调查了冬给措纳湖底地形、地貌,采集了湖相沉积物样本.在湖的东岸和西岸发现多年冻土,湖泊西北山谷观察到古冰川活动遗迹.初步推测该湖是由断陷沉降形成.为进一步分析湖区气候和环境变迁,联合小组拟定2007年3月份钻取湖芯.
The inland lakes and their lacustrine sediments in the hinterland of the Qinghai-Tibet Plateau can more accurately reflect the characteristics of climate change, and have attracted the attention of Chinese and foreign scientists in the study of the environmental changes in the plateau. From August 15 to September 10, 2006, Quaternary permafrost, geomorphology and geology were investigated in the area around the Dongzao Lake in the northeastern Qinghai-Tibet Plateau, and preliminary digital elevation analysis was conducted on the terrace of lake bank.The topography, topography, Permafrost was found on the eastern and western coasts of the lake and the remains of ancient glaciers were observed in the northwestern lakes of the lake, suggesting that the lake was formed by the subsidence of rifts.For further analysis of climate and environmental changes in the lake area, The team plans to drill Lake in March 2007.
