中国黄土高原孢粉研究及其进展
首发时间:2011-05-22
摘要:在全球气候变化研究的驱动下,近年来中国黄土高原孢粉研究在经受各种挑战的同时也取得了长足的发展。本文主要就黄土孢粉的提取方法、研究成果与进展以及研究过程中存在的问题进行了归纳总结,并提出了几点展望。通过对黄土孢粉各种提取方法对比发现,HF筛选法是比较理想的黄土孢粉提取方法。黄土高原长尺度(百万年)的孢粉研究相对较少,而万年、千年尺度的相对较多。近些年来,中国黄土高原孢粉研究沿着由定性向定量、低分辨率向高分辨率的总体方向发展的同时,其全新世以来的孢粉古植被地方性分异研究也得到了普遍的关注。

Pollen Research of Chinese Loess Plateau
Abstract:The study of pollen from loess sediments, while experiencing the challenges, has also made great strides under the research of global climate change. This review is mainly focused on the methods of pollen extraction from loess sediments, the research progress of the pollen on the Loess Plateau and existing problems are summarized, and a few prospects in this field are also made. By comparing the various methods, results indicate that HF method is an ideal procedure of loess pollen extraction. The large scale (million years) researches of pollen from loess sediments are few relatively while the short scale (ten thousand, thousand years) are much more and detailed. Recent years, the pollen research of Chinese Loess Plateau has transformed from qualitative to quantitative and from low resolution to high resolution. The research of the vegetation types of different geomorphological units has also been made generally concern on the Loess Plateau since Holocene.
