摘要:

第四纪风沙环境的研究对于人们了解重大气候环境变迁有着重要的意义。对于第四纪风沙环境的研究主要通过对环境变化的信息载体进行分析,提取其中有关风沙环境变化的证据,从而对古环境进行推测与重建。本文阐述了当前国内外学者在进行第四纪风沙环境研究时使用的证据(形态学证据、沉积学证据和生物学证据),分析了利用这些证据时存在的问题,并对未来的研究趋势作了分析,指出各种证据的综合使用以及提高定年的准确度仍是未来的研究重点。

Abstract:

The research of Quaternary Aeolian environment has great significance to understand the momentous climatic changes. As the time series of instrumental observation data is too short to reconstruct the past environmental variables, the reliable proxies have been widely applied to the Quaternary Aeolian environment research. Based on the analysis of the proxies and extracting the valuable information and evidences about the climatic variables, the long time series of past environmental changes can be reconstructed. This paper formulates the evidences (morphological evidences, sedimentological evidences and biogeomorphical evidences) used in the Quaternary Aeolian environment research, presents the problems existed in using the evidences, analyzes the tendency of the future research, and points out that the synthetic using of proxies and improving the precision of dating are still the emphases.

Key words: biology, morphology, quaternary aeolian environment, sedimentation
