| 摘 要： | 阔叶红松林择伐后伐根在土壤动物和微生物的共同作用下逐步分解,文章以阔叶红松林重要树种蒙古栎的伐根为研究对象,选取14a范围的蒙古栎伐根分解的残留物,分离出其中的大型土壤动物、干生中小型土壤动物,鉴定种类,统计计数。分析在蒙古栎伐根分解的过程中,土壤动物的动态变化。结果表明,随深度增加,蒙古栎伐根上土壤动物类群和数量逐渐减少。

| Abstract: | In the broadleaved-korean pine forest,stumps were decomposed by animals and microorganism stepwise.This study focuses on the decomposing process of the stump of the Quercus mongolica as the broadleaved-korean pine forest's important species.Certain soil samples are collected in the span of the last 14 years,and the big soil animals is distinguished from those in medium and small sizes which prefer to live in the dry atmosphere.After identifying the species,and analyzing the dynamic changing of them during the decomposing process,we reveal that along with the increasing of the depth,the kind and the quantity of the soil fauna,which inhabit in the stump,are decreasing by contraries. |
