| 摘 要： | 全新世气候变化是当前地球科学研究的重点与热点之一。洞庭盆地全新统是重建区域古气候的良好材料。介形类为重建古气候的良好指标。洞庭盆地介形类包括6属10种,仅比利时舍氏玻璃介(相似种)Schellencandona cf.belgica对水深敏感,其余属种均不敏感。采用加权平均二项式回归法建立基于S.cf.belgica的水深转换函数,该函数具有较好的预测能力。本研究可为定量重建洞庭盆地全新世古气候奠定必要基础。

| Abstract: | Holocene climate change is a focus and hotspot of present earth science research.Holocene sediments from Dongting Basin are nice archives for reconstruction of regional palaeoclimate.Ostracods are a good indicator for palaeoclimate reconstruction.Ostracods from Dongting Basin include 6 genera 10 species,and Schellencandona cf.belgica is sensitive to water depth only.Transfer function for water depth based on ostracods(Schellencandona cf.belgica) using method of weighted average binomial regression(WA-BR) is established,which is of good predictive ability.The study can provide necessary foundation for quantitative reconstruction of Holocene palaeoclimate of the basin. |
