在被认为孢粉贫乏的黄土中分析出了大量孢粉，首次作出了黄土地层的孢粉浓度图式。根据１０余个剖面上孢粉组合的变化，阐明了晚更新世的植被与气候在时间上演替与空间上分布的规律，证明了各地植被在时间上的演变韵律十分相似，说明它们同受全球气候变化的控制，但同一时期在空间上各地植被不尽相同，此乃局地自然环境差异所致。根据植被变化重建了古气温曲线。 A large amount of sporopollen was analyzed in the loess, which is considered to be poor in sporopollen, and the sporopollen concentration diagram of the loess formation was first made. Based on the changes of sporopollen assemblages in more than 10 sections, the law of temporal succession and spatial distribution of vegetation and climate in the late Pleistocene was clarified, and the evolution rhythms of vegetation in different places were very similar, indicating that they are similar The control of global climate change, however, varies from place to place over the same period. This is due to the differences in the natural environment of the area. The paleoclimate curve was reconstructed according to the vegetation change.
