试论内陆干旱区新疆巴里坤湖晚更新世气候变化格局

西部内陆干旱区晚更新世以来气候变化格局一直是许多地学工作者极为关注的问题。不少研究者认为西部内陆干旱区古气候变化的格局和东部季风区相似。即冰期是干冷的、间冰期是温暖的。作者认为西部干旱区随着第四纪不同的发展阶段与其相应的古气候也随着作阶段性的变化。经综合分析研究表明,当进入晚更新世古气候演变为不同程度的冷湿与暖干相结合的气候格局。即表现为冰期冷湿与间冰期暖干的气候型。从此取代了早、中更新世的与东部季风区相似的冷干与暖湿相结合的气候型。

A DISCUSSION ON THE PATTERN OF CLIMATIC CHANGES DURING THE LATE PLEISTOCENE EPOCH IN THE BALIKUN LAKE OF THE INLAND XINJIANG ARID REGION

The pattern of climatic changes in the inland arid regions of westernChina following the late Pleistocene Epoch has been a concern of manygeologists.Some of them feel that the pattern of ancient climatic changesin the inland western China is similar to that of the eastern monsoon re-gions of China, in that it was dry and cold during the glacial stages andwarm during the interglacial stages. The author suggests that the ancientclimate in the western inland region be changed periodically with the diff-erent stages. Through comprehensive analysis of the climate in the latePleistocene Epoch was found to be cold and humid during the glacial stagesand warm and dry in the interglacial stages.
