Some unavoidable methodic and methodological problems arising at each stage of the classification of objects by the methods of hierarchical clustering are shown on the concrete (biogeographical) and abstract--numerical examples. Reasons which cause these problems and possible ways of minimization of cluster analysis artifacts are discussed. Unavoidable constrains in interpretations of dendrograms obtained by means of agglomerate algorithms are indicated.
通过层次聚类方法对对象进行分类的每个阶段出现的一些不可避免的方法和方法论问题，在具体（生物地理）和抽象数值示例中得到了展示。讨论了导致这些问题的原因以及将聚类分析伪像最小化的可能方法。指出了通过凝聚算法获得的树状图解释中不可避免的限制。
