摘要: 以针阔混交林及落叶阔叶林为例,探讨了森林凋落物与大型土壤动物的相关关系.研究表明,森林凋落物中大型土壤动物的个体数依林型、凋落物厚度、凋落物量不同而异,凋落物的分解程度影响大型土壤动物的种类、数量分布,凋落物中矿质元素含量与大型土壤动物体内矿质元素含量相关较好,凋落物中微量元素含量与大型土壤动物体内微量元素含量明显不相关.本研究为揭示大型土壤动物在凋落物分解中的作用,进而为森林的经营和保护提供科学依据.

关键词: 凋落物, 大型土壤动物, 矿质元素, 微量元素

Abstract: Correlation between iorest litter and soil macroanimals is studied with coniferous broad-leaved mixed forest and deciduous broad-leaved forest as an example. The results show that the individual number of soil macroanimals in forest litter varies with forest type and thickness and amount of litter. The decomposition rate of litter affects the species composition of soil macroanimals and their distribution. The content of mineral element in litter is well associated with that in soll macroanimals in litter decomposition is revealed, which provides a scientific foundation for forest management and preservation.

Key words: Forest litter, Soil macroanimal, Vineral element, Microelement
