- Title:
- Pollen Analysis of Holocene Loess and Vegetation Evolution in Yan’an Area

- 摘要:
- 采用孢粉分析和14C测年法，通过花粉植被化模拟技术，研究了延安地区全新世的孢粉组合特征及其古植被的演替历史。全新世时期延安地区的气候变化在全球和中国区域气候的格局下，也呈现出早、中、晚三个气候阶段，中期（7500～4500a）为气候最佳期，与之相对应的植被演替也分为三个阶段：中期植被为松、桦、栎、漆为主具亚热带成分的暖温带落叶阔叶林，早期和晚期的气候较干冷，乔木花粉的含量减少，呈现以松、栎为主的暖温带针阔叶混交林。
- Abstract:
- The authors present pollen assemblages and radiocarbon dating of the Holocene loess in Yan’an area.Using the pollen vegetation modeling technique, the vegetation evolution during Holocene was reconstructed.Under the background of global and regional climatic changes, Yan’an had been subjected to a whole cycle change of climate.In the middle of Holocene, the climate was at the optimum warm and humid stage, and the vegetation type was dominated by subtropical deciduous broad leaved forest, which mainly consisted of Pinus, Betula, Quercus and Rhus.During the early and later Holocene, with the dryer and cooler climate, it became coniferous broad leaved mixed forest, which mainly consisted of Pinus and Quercus.
