摘要
[目的]探讨不同林型土壤动物群落的结构特征和差异。[方法]对浙江天童灌丛、马尾松林、木荷林、栲树林4种林型中土壤动物进行调查。[结果]4种林型土壤动物类群组成存在差异,优势类群也各异,线虫为优势类群,但弹尾目在4种林型中均为常见类群,木荷林优势类群只有线虫,蜱螨目和弹尾目为常见类群;处于传统意义上演替顶极的栲树其土壤动物群落类群数和个体数并未达到最高,而处于演替中期阶段的马尾松在群落类群数(30)和个体数(占总捕获量的44.62%)达到最高;马尾松林土壤动物类群数和个体数都最多,因而其密度-类群指数、丰富度和优势度指数也最高;栲树林样地的均匀度指数和Shannon-Wiener指数最高。[结论]不同林型土壤动物群落差异明显,其总体趋势有待进一步研究。
[ Objective] The aim of the study was to ascertain the feature,differences and changes of soil animal communities among the four types of forest in Tiantong,Zhejiang Province. [Method] Soil animals of four kinds of forest were investigated. [Result] The results indicated that there were differences in the composition of the soil animal communities. Collembola was no longer the dominant group but the common group. Nematoda was the only dominant group in the Schima superba comm. The soil animal groups and the individual number were both the highest in the Pinusm assoniana comm.,so were the Density-Group index ,the Margalef Abun-Dance index and the Simpson Dominant index. The Castanopsis fargesii comm. had the highest level in Evenness index and Shannon-Wiener index. [Conclusion] It was quite clear that soil animal communities of the four types of forest in Tiantong are different,while the trend of the law was expected to do far more research.
