摘　　要： 对不同海拔毛竹林节肢动物群落的研究表明:海拔400、540、660、820和950m林下层分别有节肢动物93、76、76、61和48种,竹冠层分别有139、125、105、96和74种 各海拔林下层优势种和丰盛种多为天敌和中性昆虫,竹冠层则均为刺吸性害虫(螨) 随着海拔升高,二层次的物种数、多样性、均匀度均逐渐降低 随着海拔差异增大,群落物种组成差异增大。 The results of research on arthropod communities in different altitudes Phyllostachys heterocycla cv. pubescens forests in Sanming, Fujian from 2001 to 2002 indicated:there were 93,76,76,61 and 48 species of arthropods in the underlayer and 139,125,105,96 and 74 species of arthropods in the canopy in altitude 400,540,660,820 and 950 m bamboo forests respectively. Most of dominant and rich species in the underlayer were natural enemies and neutral insects,but those in the canopy were all sticking-sucking pest insects and mites. The richness,diversity and evenness in the underlayer and in the canopy all played down with the rising of altitude height.The variation of species in communities rose with the rising of variation of altitude, however, in which the variation of arthropods in the canopy was less than that in the underlayer.
