Present study focused on how the presence of decaying wood affects soil environment including its biota. The study was carried out in the montane spruce forest, disturbed by wind and bark beetles in Trojmezná Mt. of the Bohemian Forest in the Czech Republic. According to the results, presence of decomposing wood influenced soil environment in terms of its chemical properties by increasing soil pH and total carbon content significantly in soil below the trunks compared with soil from further distance. Decomposing wood did not affect total density and species richness of Collembola, but it had a significant influence on species composition and some species were more abundant in soil right below the trunks whereas others preferred soil environment further from them. Finally, significant relations, both positive and negative, were recorded between some Collembola species and ammonium. Thus, this substance might play a role of a volatile attractant in soil environment.
本研究主要关注腐朽木材的存在如何影响土壤环境及其生物区系。该研究在捷克共和国的特罗伊梅日纳山的山地云杉林中进行，这里受到风和树皮甲虫的干扰。结果表明，与远离树干的土壤相比，腐朽木材的存在通过显著增加树干下方土壤的 pH 值和总碳含量，对土壤环境的化学性质产生了影响。腐朽木材对弹尾目动物的总密度和物种丰富度没有影响，但对物种组成有显著影响，一些物种在树干下方的土壤中更为丰富，而其他物种则更喜欢远离树干的土壤环境。最后，一些弹尾目动物物种与铵之间存在显著的正相关和负相关关系。因此，这种物质可能在土壤环境中充当挥发性引诱剂的作用。
