| 摘 要： | 六盘山位于我国黄土高原西部，秦岭西段以北，是一座南北走向的狭长石质山地，具明显 的温带大陆性季风气候。地处温带森林草原地带，地带性植被类型为落叶阔叶林和草甸草原。 本文运用相似系数法和组平均法等数学方法进行森林植被的分类。通过比较和分析，划 分出9个群系，初步建立六盘山森林植被的分类系统。这一结果与定性分类(依据植物群落学——生态学原则)所得出的结果基本相同，说明本文所采用的数量分类方法和分类指标是适用于温带地区森林植被的分类。

| Abstract: | The Liupan Mountain,a long and narrow stony mountain with a S-N strike,is situated in the west of the loess plateau.It has an obvious temperate continental monsoon climate,Because of its lying in the temperate forest-steppe belt,its zonal vegetation types are deciduous broad-leaved forests and meadow steppes. The numerical methods of similarity coefficient and group average were used in this paper for classifying the forest vegetation.Through comparison and analysis these forest types are divided into two vegetation types,five formation groups and nine formations,so that a classification system for the forest vegetation of the Liupan Mountain is tentively established.The results are very similar to those of the qualitative classification(based on the plant community-ecology principle),which is demonstrated by the fact that these numerical classification methods and indexes are suitable for the temperate forest. |
