摘要:

基于前人山西榆社盆地张村植物大化石和花粉组合资料,运用分布区叠加分析法,初步重建了山西张村上新世气候参数值和古海拔高度。研究结果表明,由不同数据来源计算的张村古气候参数数值变化范围大多落在今天的暖温带到北亚热带区间;依据原地埋藏的植物大化石组合推出上新世时山西张村地区存在植被垂直分带,周围为山地地形,由此估测的古湖海拔高程范围在400~1 000 m,明显低于今天约1 043 m的海拔高度,表明在上新世之后位于黄土高原东缘的张村地区还有抬升;支持前人关于更新世以来晋东南地区的整体缓慢抬升的推测。

Abstract:

 The Pliocene climate and elevation of Zhangcun basin are estimated using ODA method, based on the data of both plant fossil and pollen assemblages. The results show that (1) the data of the palaeoclimate parameters obtained from ODA analyses of both megafossil and three sets of pollen assemblages mostly fall into the range of modern warm temperate and northern subtropical zones; that (2) the palaeoelevation of Zhangcun estimated by the assemblage of plant megafossils found in situ ranges from 4001000 m a.s.l. and obviously lower than today (1043 m a.s.l.). The findings might indicate the uplift of Zhangcun basin on the east edge of the Loess Plateau after the Pliocene, and support the former view that the elevation of southeastern Shanxi had risen slowly since the Pleistocene.

Key words: palaeoclimate, palaeoelevation, Pliocene, Zhangcun, Shanxi, , China
