摘要
通过对正蓝旗闪电河剖面孢粉资料的分析,重建了内蒙古中部地区全新世以来古植被及古气候的演变过程。全新世早期气候温凉略干,为草原型植被或稀疏草原型植被;中期气候相对暖湿,为森林型植被;后期气候温凉偏干或凉爽偏干,为稀疏草原型植被或草原型植被。
The according to the Holocene vegetation and climatic evolution in central Inner Mongolia was reconstructed palynological records of the Shandlanhe section in Zhenglan Qi. The vegetation was dominated by steppe or sparse steppe in the early Holocene, corresponding to a warm and dry climate The vegetation in the middle Holocene was forest-type, indicating a relatively warm-wet climate. the late Holocene, the vegetation again changed During to steppe or sparse steppe, suggesting that the climate tended to be warm-slightly dry or cool-slightly dry.
