花粉分析及其在林业上的应用

花粉分析是现今研究森林植被史及其古生态的主要手段。由于植被与其所产生的花粉组合的关系十分复杂，化石化粉图谱的解释是花分析中一个关键问题。目前主要有两种解释方法，其一是将化石化粉谱与现代不同植被类型所产生的花粉谱作比较，找出与之相似的现状花粉谱，根据产生相似花粉谱的现代植被来推论森林植被的变迁；其二是用Ｒ值校正化石花粉的百分含量，该方法有待完善。

Pollen Analysis and its Application in Forestry

Pollen analysis is a main research method of reseach on forest vegetation history andpaleoecology. Interpretation of pollen diagrams is a key to pollen analysis because the relation between vegetation and its pollen percentage is very complex. There are two kinds of interpretationmethods: one way is to find out the similar pollen diagrams by comparing the fossil pollen diagrams with the modern pollen diagrams which are produced by different types of vegetation,and deduces paleovegetation based on the similar pollen diagram; the other one is to use R-valuesto correct fossil pollen percentages. However the method needs to be perfected.
