摘要
论述了第四纪孢粉时间序列和孢粉空间模型在不同尺度上的时空代表性，同时介绍了一些相关的研究方法和主要成果。利用数理统计方法来定量恢复古气候已成为目前第四纪孢粉时间序列研究的一个发展趋势。各种尺度的第四纪孢粉空间模型图可以反映植被对第四纪气候变化的响应。根据孢粉数据与气候变量之间的函数关系还可换算成古气候图。此外，在全球气候模拟和植被模拟中，孢粉数据成为必不可少的诊断工具。
Quaternary palynological time series and spatial patterns of different scale hierarchies are discussed in this paper.Some related methods and principal results are also introduced.The palynological studies today in the world,including those of million year duration down to those of less than hundred years,may represent various characteristics of environmental change.Applications of transfer functions and other statistic methods to reconstruct the paleoclimate flucturations is being a trend of pollen sequence analysis. The restoration of the Quaternary spatial distribution of vegetation of different scales is so call Quaternary pollen spatial pattern.This pattern reflect the spatial response of vegetation or pollen types to the Quaternary climate changes.The quantitative climate calibration from pollen record can also help to establish the spatial paleoclimate characters.Additionally,pollen data is recently a diagnostic tool to validate climate and biome models of global scale.
