| Spore and Pollen Characteristics and Environment Evolution in Datong Basin Since Holocene |
| Based on a study of the spore-pollen flora from the Dongshuitou section of Datong basin, the authors revealed evolutionary characteristics of the climatic environment in Holocene. The results indicate that the herb has been dominant all the time since Holocene. Although the deciduous and broad-leaf plants and the coniferous plants sometimes possessed important positions in the woody plants, they have not yet formed the stable forest landscape. The vegetation types in the study area are dominated by veld and grassland plants, suggesting a warm and dry climate. The megathermal period of the Holocene lasted from 8.5 kaB.P. to 4 kaB.P. when the climate was unstable, which has good comparability with that of the Loess Plateau. |
