摘要: 为确定不同环境因子对塞罕坝机械林场林下草本植物物种多样性的影响程度,通过样地调查法对该区物种进行了调查,并对调查数据采用灰色关联法进行了处理和分析。结果表明:调查区共有林下草本植物79种,优势种主要为细叶苔草、小花糖芥、中华隐子草;草问荆、蒲公英、唐松草等为常见种;苦荬菜、银莲花等为偶见种。对物种丰富度影响最大的2个林分因子分别是树高和胸径,对物种丰富度影响较大的生境因子依次为海拔高度和坡度。

关键词: 灰色关联, 物种多样性, 林下植被

Abstract: Investigation was carried out to determine the effects of the different factors on undergrowth herb species diversity in Saihanba Forestry Centre. Grey sequence method was used to treat and analyze the data. The results are as follows: there are 79 undergrowth herb species in the survey area and the dominant species are mainly C. rigescens, E. cheiranthoides, C. chinensis; E. pretense, T. mongolium, T. aquilegifolium,etc. are common species and I. denticulate, A. cathayensis,etc. are the occasional species. Height and DHB have the largest effects on species richness next to altitude and slope.

Key words: grey sequence, species diversity, undergrowth vegetation
