| 摘 要： | 通过新疆东昆仑库木库里盆地古近-新近系孢粉分析，将浙新-上新统孢粉划分为7个组合带。根据孢粉组合特征，探讨了造山带上叠库木库里盆地渐新-上新世由稀树草原-森林-森林草原-荒漠草原-森林草原的古植被的演替与暖→冷→暖→冷的古气候演变特征，得出至上新世末期昆仑山海拔已达到3000m左右的高度，这对研究青藏高原的隆升提供了重要依据。

| Abstract: | Sporopollen analysis of the Paleo-near System in the Kumukuli basin eastern Kunlun of Xinjiang divided the sporopollen of the Oligocene Pliocene series into seven compositions. The evolution features of the paleoclimate changing in warm cold warm cold and the alternation of the paleobotany from spars tree grassland forest forest grassland desert grassland forest grassland in the Oligocene Pliocene series of the Kumukuli in the orogenic zone discussed in this paper have made a conclusion that the Kunlun Mountain was up to an elevation above the sea level about 3,000m in the end of Pliocene series. |
