Another distinction often made in the literature of numerical taxonomy is that between divisive and agglomerative approaches . 在文獻(xiàn)的版值分類方法中,還存在另一個(gè)區(qū)別,即劃分法和聚合法。
The rapid development of numerical taxonomy over the past fifteen years has contributed to the development of parallel methods in plant ecology . 數(shù)值分類學(xué)的迅速發(fā)展,雖是近十五年的事,但它對(duì)植物生態(tài)學(xué)中相應(yīng)方法的發(fā)展作出了貢獻(xiàn)。

Numerical taxonomy is a classification system in biological systematics which deals with the grouping by numerical methods of taxonomic units based on their character states. It aims to create a taxonomy using numeric algorithms like cluster analysis rather than using subjective evaluation of their properties.
