    摘要:

    2003年10~11月,对金华北山落叶阔叶林和常绿阔叶林大型土壤动物进行了调查,共获得大型土壤动物1445只,隶属3门,7纲,18目。其中近孔寡毛目(线蚓科)、鞘翅目为优势类群,正蚓目、弹尾目、膜翅目、双翅目、蜘蛛目、蜱螨目为常见类群。通过对两个样地大型土壤动物的对比分析,落叶阔叶林和常绿阔叶林的大型土壤动物优势类群、常见类群组成成分及类群数基本相同,群落多样性和均匀性指数差异不大。在垂直分布上,两者的变化基本一致,类群数和个体数量随土层的加深呈递减趋势,且表聚现象明显。土壤养分和pH值与大型土壤动物群落组成和结构密切相关。

    Abstract:

    From October to November 2003, soil macrofauna in deciduous broadleaf and evergreen broadleaf forests in Mountain Bei of Jinhua were investigated and 1445 individuals were collected. They belong to 3 phyla, 7 classes, and 18 orders, among which the Oligochaeta (Enchytraeidae) and Coleoptera, were the dominant genera (orders) and Lumbricida, Collembola, Hymenoptera, Diptera, Araneae and Acarina were common genera. Comparison between the two different types of forests in soil macrofauna showed that there was not much difference between the two in composition and population of the dominant genera and common genera of soil macrofauna and not in diversity and homogeneity index of soil macrofauna communities, either. In vertical distribution of soil macrofaunas, the two showed a similar trend, i.e. soil macrofauna were decreasing in numbers of genera and individuals with the increase in soil depth, and tended to assemble in the surface layer. The composition and structure of soil macrofauna were closely related to soil nutrients and pH. This investigation was aimed to reveal composition and distribution of soil macrofauna and promote research on the soil macrofauna and their functions within the ecological system in Mountain Bei of Jinhua. The findings would provide a scientific basis for further research in subtropical regions.
