通过对位于干旱-半干旱区的内蒙古盐湖中沉积物提供的环境和气候条件之相关讯息,能解读出最近23kaB.P.以来详细的气候变化:据今20~23kaB.P.期间,气候呈温干特征;之后,气候变冷进入末次冰期的极盛期。在14.5~20kaB.P.期间,降水量大幅度减小,夏季风萎缩,而冬季风更加强劲。自14.5kaB.P.开始,全球进入冰消期。约在11kaB.P.左右,出现异常降温的新仙女木(YoungerDryas)突变事件。自2.3kaB.P.以来,夏季风乃处于衰退减弱之趋势,其中仍有明显的气候波动。台湾的撤退池和嘉明湖沉积物,则记录着最近数千年来的气候变动,其中的冷暖变化竟也大多与内蒙古盐湖的记录相对应。似能说明20~23kaB.P.以来较大范围的气候变化。
The most recent 23kaB can be read by providing information on the environmental and climatic conditions provided by the sediments in Inner Mongolia Salt Lake in arid and semi-arid regions. P. Since the detailed climate change: According to this 20 ~ 23kaB. P. During this period, the climate was warm and dry; after that, the climate cooled into the extreme period of the last glacial period. In 14.5 ~ 20kaB. P. In the meantime, the precipitation decreased drastically, the summer monsoon shrank and the winter monsoon became stronger. Since 14.5kaB. P. Beginning, the global ice into the consumer. About 11kaB. P. , YoungerDryas mutation occurred abnormal cooling. Since 2.3kaB. P. Since the summer monsoon is in the trend of declining recession, of which there is still obvious climate fluctuations. The retreat ponds in Taiwan and sediments in Jia Ming Lake record the recent climate changes for thousands of years. Mostly the changes in the warm and cold climate correspond to the records of Salt Lake in Inner Mongolia. It seems that 20 ~ 23kaB. P. Since a wide range of climate change.
