摘要
简要回顾了国内外有关2.5Ma以来古气候环境演变代用指标的理论及其应用研究成果,对磁化率、孢粉、δ13C、粒度、地球化学及分形等气候环境代用指标作了重点评述,并对古土壤磁化率增强的物理机制和δ13C恢复古环境的理论基础作了初步分析,以及在此基础上对今后的研究趋势进行了探讨。
The theory and its applications at home and abroad on the indicators of palaeoclimatic and palaeoenvironmental evolvement in the past 2.5Ma are reviewed in this paper, with emphasis being put on magnetic susceptibility, pollen,δ^13C, grain size, geochemical characterization and fractal, including an initial analysis made for the physical mechanism on the increase of magnetic susceptibility and the theory on the palaeoclimatic and palaeoenvironmental construction with δ^13C. Based on this review, future research tendencies are discussed.
