摘　　要：对冰雪灾害后杨东山十二度水省级自然保护区的森林大型土壤动物功能群和生态特性进行了调查。结果表明:在海拨700～1000m的常绿与落叶阔叶混交林中,膜翅目、鞘翅目昆虫为数量上的优势类群。从生物量来看,优势类群为蚯蚓、鞘翅目昆虫、双翅目和鳞翅目幼虫。将研究区的大型土壤动物划分为腐食性、植食性和捕食性动物3个功能类群,其中腐食性动物的生物量所占比例最大,而植食性动物的数量占优势,捕食性动物两者所占比例较小。An investigation on functional groups of soil fauna and their ecological characteristics were conducted in Yangdongshan Shierdushui Nature Reserve in North Guangdong Province after the ice and snow disaster in 2008. Results show that Hymenoptera and Coleoptera are dominant groups in quantity in the evergreen coniferous and deciduous broad-leaved mixed forests at elevations of 700-1 000 meters. Earthworm,Coleoptera,Diptera larvae and Lepidoptera larvae are dominant groups in biomass. Soil animals in the study area are divided into three functional groups based on their feeding functions,that is,saprozoic,phytophage and predacity animals. The saprozoic animals are predominant in biomass compared with other two groups; the phytophage animals are dominant in quantity while the predacity animals are lowest both in quantity and in biomass.
