为了给深入揭示喀斯特生物多样性及其功能提供基础资料。在2010年8月,对贵州喀斯特高原峡谷石漠化地区土壤动物功能类群进行了野外调查和室内分离、鉴定。结果表明:将该研究区土壤动物划分为腐食性、植食性、捕食性和杂食性动物4个功能类群。其中,杂食性土壤动物的个体数占总捕获量的比例为最大,捕食性土壤动物为最小。土壤动物个体数在水平分布上差异明显,类群数分布较均匀。土壤动物垂直分布格局研究表明,各样地都表现为明显的表聚现象。不同样地的特有类群反映出各自局地环境的特殊性,它们对生态系统具有指示作用。
In order to provide in-depth information on karst biodiversity and its function, In August 2010, the soil fauna functional groups in the rock desertification area of Guizhou Karst Plateau were field surveyed and isolated and identified. The results showed that the soil fauna in the study area was divided into four functional groups: carnivorous, herbivorous, predatory and omnivorous animals. Among them, the proportion of omnivorous soil animals in the total number of individuals to capture the largest, predation of soil animals is the smallest. There was significant difference in the horizontal distribution of soil animal individuals, and the population distribution was more uniform. The study on the vertical distribution of soil fauna shows that all kinds of land show obvious phenomenon of surface aggregation. The peculiar taxa of different plots reflect the peculiarities of the local environment and they have the instructional function to the ecosystem.
