河北围场御道口地区中全新世以来古植被与古气候演变
Variation of Paleovegetation and Paleoclimate since the Mid-Holocene in the Yudaokou Area of Weichang County, Hebei Province
摘要
Abstract
Based on the high-resolution sporopollen records of the section in the Yudaokou pasture of Weichang County, Hebei Province, the variations of climate and environmentsince 6000 a B. P. ( 14 C dating is 5. 7 ka B. P. atthe section bottom ) in the Yudaokou area of Weichang County were analyzed. The regional features of sporopollen assemblages showed thatthe paleocli-mate in the Yudaokou area experienced seven stages since 6000 a B. P. : cool and slightly wet-cool and dry-warm and slightly wet-warm and wet-warm and slightly wet-warm and wet-cool and slightly dry. Vegetation landscape was mainly coniferous for-est-steppe vegetation, which was dominated with Pinus and Artemisia and scattered with a smal amountof Betula, Quercus, and other deciduous trees and shrubs in the forest. The paleoclimate change pattern since the Holocene in the study area is similar to thatin other regions of China.关键词
