Abstract:

A model for China biome reconstruction was deduced from 641 original pollen data of surface samples by biomazition procedure developed by Prentice et al . Fourteen biome types of China were recognised based on 31 plant fuctinooal types from 686 pollen types. The procedure successfully delineated the major vegetation types in China and, therefore, can provide an objective methord for China biome reconstruction of geological time, e.g. for 6 ka BP and 18 ka BP.

表土孢粉模拟的中国生物群区
中国第四纪孢粉数据库小组*

摘要： 根据中国第四纪孢粉数据库提供的641 个表土孢粉资料，利用孢粉生物群区化方法，建立了具有686个孢粉类群、31 类植物功能型和14种生物群区的孢粉生物群区化模型。经过检验，该模型在模拟中国生物群区、生物群区垂直分异和水平梯度分析方面均取得理想结果。模型已实现了计算机程序化，为重建过去地质历史时期的古生物群区和古气候分析，提供客观、准确的模型工具。
