摘要
根据组分多度比较分析的概念，建立了组分多度相似相异百分率的计算公式和两个详略不同的相似相异等级标准。根据对三尖杉属（Cephalotaxus）在云南的分布格局间的亲和性分析，表明组分多度比较分析具有了分析严密、计算简单和结果直观等优点。
Based on the concept of comparison and analysis of co nstituent abunda nce, formula to calculate similarity / diversity percentage of constituent abund ance and two different standards of similarity / diversity grade have been const ructed. Analysis on compatibility of distribution patterns of Cephalotaxus in Yu nnan shows that the comparison and analysis of constituent abundance has the adv antages of compact analysis, simple calculation and obvious results.
