湖北郧县黄坪村剖面记录的全新世成壤特征及气候演变
Pedogenic Characteristics and Climate Evolution in the Holocene Recorded by Huangpingcun Profile in Yunxian Basin of Hubei
摘要
Abstract
The profile pattern, age framework and the magnetic susceptibility, granularity, micromor-phology, loss on ignition and Rb/Sr ratio of every stratigraphic unit of Huangpingcun( HPC) profile in Yunx-ian Basin of Hubei Province were analyzed and compared.The results showed that the HPC profile recorded the environment features and evolution with the stratigraphic sequence of TS-L0 -S0 -Lt -L1 .The order of weathering intensity for each stratum was paleosoil S0 >transitional loess layer Lt >holocene loess L0 >Malan loess layer L1 .The differences between different strata revealed the climate evolution in the Holocene of Yunx-ian Basin:the climate got warmer from 11 500 a B.P.to 8 500 a B.P.,was warm and humid from 8 500 a B. P.to 3 100 a B.P.,and worsened to dry and cold from 3 100 a B.P.to now.关键词
