中国内蒙古哈马尔太碱湖Ha01孔岩心13000a以来的古气侯记录

A PALIOCLIMATOLOGIC RECORD FOR A PERIOD OF THE PAST 13 THOUSAND ThARS FROM THE DRILLING OF THE HA01 HOLE IN HAMAERTAI SODA LAKE OF INNER MONGOLIA,CHINA

通过对内蒙古哈马尔大碱湖Ｈａ０１孔岩心古气候记录的研究，划分出１３０００ａ以来的１０个气候期及若干气候阶。对比表明，与全球气候变化是一致的。在末次冰期盛冰期之后，冰后期之前，有三次明显的急速降温，先后有老仙女木冰阶、中仙女木冰阶和新仙女木冰阶；冰后期以来，有两次大幅度的降温事件，均具有全球性，一次冷点是７６４０ａＢ．Ｐ，一次冷点为５０００ａＢ．Ｐ，前者相当Ｄｅｍｏｎ称作的第一新冰期，后者相当第一新冰期。近２０００年该盐湖的气候变化与中国历史文献资料相吻合。

AbstractThe different climatologic stages, along with several varying climatologic phases, are recognized on the basis of paleoclimatologic researches on the drilling core of the Hao1 hole positioned in Hamaertai soda lake of Inner Monsoila, showing accordance to some extent with the overall changing trend of globle climate. After the peak of the last glacial stage and before the end, there occurred three periods of dramatic drop in temperature, respectively representing oldest-, older- and Younger Dryas Glacial period Also, two large- scale and golbewide events of lowering temperature have taken place since the end of the last glacial stage, one, in 7 640 aB. P., corresponding to Denton glacial stage and named the First New Glacial Period compared with the other in 5 000 aB. P., analogous to the Second New Glocial Period. The climatologic evalution of the soda lake throughout the past 2000 years is fairly identical to that documented in the Chinese historical literature concerning this field.
