摘要: 对湖南会同不同年龄的杉木人工林群落,以重要值为定量值,按龄级用区系排队法和极点排序法进行了类型划分,把杉木林从新造林到37年生老龄林,共8个龄级(每5年为一个龄级)划分为7大群落类型,并分别阐明了各类型的外貌结构、物种组成,分析了杉木人工林林下植被演替特点。

关键词: 杉木人工林, 极点排序, 类型划分, 植被演替

Abstract: Regarding importance value as the quantitative factor Chinese fir communities with different age in Huitong,Hunan,were classified and ordinated by the use of floristic clas-sification and polar ordination.Communities from newly afforested stand to 37—year—old stand,consisting of 8 age classes,were divided into seven community types.Phys-iognomy structure and species composition were discussed for each community type.Fi-nally,the characteristics of understory succession were also analysed.

Key words: Chinese fir, Polar ordination, Vegetation succession
