| 摘 要： | 为了深入了解濒危植物七子花林中土壤动物的群落特征,比较分析四季林分中不同海拔高度土壤动物群落结构的差异性,于2000年4月~2001年4月,对天台山不同海拔七子花林分的土壤动物进行取样分析。全部调查所得大中型土壤动物4门13纲27个类群,以蜱螨目和弹尾目为优势类群。林中3个样地的土壤动物在个体数量、类群数和DG指数上有较大差异,处于中海拔地区呈共优群落的林分(海拔780 m左右,人为干扰较小,仍然以七子花为优势)中土壤动物的各指标在各季节均较其他样地高,有利于土壤动物的大量繁育。方差分析表明季节、海拔和土层深度对土壤动物群落各指标都有显著影响(P<0.05t,hree-way-ANOVA),季节与海拔、季节与土层之间对土壤动物均存在显著交互作用。秋季土壤动物各指标最高,不同海拔高度下差异较大。夏季和冬季土层中的土壤动物呈逆分布现象,而春季和秋季具有表聚性特点。

| Abstract: | In order to analyze the characteristics of soil fauna in Heptacodium miconioides woodland(Hmw),the experiment was carried out on the samples of Heptacodium miconioides woodland(Hmw) at different altitudes on Tiantai Mountain in Zhejiang Province,China,from April 2000 to April 2001.We collected specimens belonging to 4 phyla,13 classes and 27 groups.There were quite differences in density,group richness and DG index in the three plots of Hmw.The indexes of soil fauna in an area moderate in altitude were high... |
