随着计算机的广泛应用和第四纪古环境研究的深入，许多数值技术被应用于孢粉分析中。采用花粉化合物-气候转换函数、花粉-气候因子转换函数、花粉-气候对应分析、花粉-气候响应面模型和共存分析方法对古环境进行了解释。由于不同的分析技术有各自的特点、适用范围和局限性，数值分析方法应相互补充、相互印证，使定量分析结果准确、客观，消除主观随意性。通过对比发现，随着古气候定量重建方法的改进，研究的准确性也在沿着提高，促进了新技术在孢粉学和古环境重建研究中的应用。
With the wide application of computers and the development of quaternary paleoenvironment studies, many numerical techniques are used in the spore-pollen analysis. Pollen compound-climate transfer function, pollen-climate factors transfer function, pollen-climate correspondence analysis, pollen-climate response surface model and the coexistence approach are adopted to explain paleoenviroments. Because different analysis techniques have respective characteristics, the applicable ranges and limits, the numerical analysis methods should supplement and confirm each other, to make the result of quantitative analysis precise and objectivity, and the subjective randomness can be eliminated. By comparison, it is found that the accuracy of researchs is getting improved along with the ameliorating of quantitative methods for paleoclimate reconstruction, which promotes the application of new artifices in Palynology and paleoenviroment reconstruction researchs.
