对章古台沙地典型人工林的大型土壤动物群落进行调查,共捕获大型土壤动物59类,1689只,隶属于2门4纲14目43科,优势类群为蚁科和金龟子科(幼虫),常见类群7类,稀有类群50类。不同人工林大型土壤动物的数量及种类组成差异很大,通常,群落的生境条件越优越,土壤动物的个体数量和种类越多。各群落土壤动物多样性指数排序为油松(2.5313)>小叶杨(2.3319)>樟子松(1.6423)>赤松(1.4651)。土壤动物的个体数量、种类、生物量及多样性指数具有较明显的时间动态变化。
The acro-soil fauna in different plantations in Zhang-gutai sandy land was investigated and the total number of them was 1689,which belonged to 59 categories,43 families,14 orders,4 classes and 2 phyla.The dominant groups were Formicidae and Scarabaeidae,and the total number of common groups was 7 categories,and the number of rare groups was 50 categories.There are significant different in the number of individuals and categories of macro-soil animals in different plantations,the more favorable condition the habitats is,the greater the number of individuals is and the more abundant the categories are.The order of soil animals' diversity index is Pinus tabulaeformis(2.5313)>Populus simonii(2.3319)>Pinus sylvestris(1.6423)>Pinus densiflora(1.4651).Individual number,category,biomass and diversity index of soil animals could be varied with time in different plantations.
