定量化重建黄土高原地区古气候,是黄土研究的新方向和大趋势.本文主要从土壤磁化率、植物孢粉、植物硅酸体和稳定同位素等替代性指标方面回顾了国内外对黄土高原地区古气候定量化研究的现状,并对研究中存在的问题进行了讨论.相关的研究结果表明,黄土高原地区的古气候定量化研究取得了积极的成果,但还仍处在初步阶段.由于指标本身存在局限性或指标与气候要素之间机理尚不十分清楚,所获得的定量化结果并不能令人十分满意.提出今后定量化重建古气候研究的重点是要进一步加强对黄土高原现代生态过程的研究,清楚地认识各指标与气候要素之间的机理和联系,建立可信的相关函数.希望对这方面的研究有所裨益.

Quantitative research is necessary for the paleoclimate reconstruction on the Chinese Loess Plateau. Based on the summarizations of the previous researches about quantitative reconstruction of the paleoclimate on the Chinese Loess Plateau, especially in the methods of soil susceptibility, pollen, phytolith, δ~(13)C_(org), and so on, the existing problems were presented and also discussed. Results show that the quantitative reconstruction of the paleoclimate on the Chinese Loess Plateau is still on the preliminary stage, though lots of positive results have been achieved. Due to the limitations of the indicators or the mechanism between climates and the indicators is unclear, quantitative results obtained are not very satisfactory. For the quantitative reconstruction of the paleoclimate on the Loess Plateau, it is important to study the modern ecologic process further, which would help to realize the mechanisms and relations between the indexes and the climatic factors and to set up the reliable functions and models.
