| 摘 要： | 运用多元分析方法中的等级聚合组平均法对怀柔山区的灌丛群落进行了群系和群丛两个等级上的划分。结果将所取的83个样方划为6个群系、16个群丛。研究表明:数量分类方法能排除过多的主观干扰,在暖温带灌丛群落分类研究中有良好的适用性。

| Abstract: | Deciduous broad-leaved scrubs in Beijing Huairou Mountainous areaare studied by using the methods of polythetic-hierarchical agglomerativegroup-average classification. Based on the results, 83 samples are divided into6 formations, 16 associations. The work,suggests that the method of clusteranalysis could avoid subjective's effect and generally produce very satisfa-ctory results to warm temperate scrubs. |
