摘要
2004年6月至10月对庞泉沟华北落叶松林土壤动物进行了深入细致的调查研究,共获样本12 927头,隶属3门7纲21目46类。其中弹尾目、蜱螨目为优势类群,鞘翅目、双翅目、鳞翅目等为常见类群。通过6块样地对比得出:天然林土壤动物类群数、个体数多于人工林,多样性也高于人工林;天然林土壤动物群落的多样性:海拔1 850 m处的>海拔1 650 m处的>海拔2 050 m处的,而人工林的群落多样性是随海拔的升高而降低;枯枝落叶层中动物个体数量占其样地总个体数的比率随海拔的升高而升高,其它各层中的比率却在降低。8月份土壤动物类群数量、个体数最高,多样性也最高。
Soil animals in Larix principis rupprechtii May forest in Guandi Mountain shanxi province , was investigated thoroughly from June to October. 12972 individuals were collected , which belonged to 3 phyla, 7classes, 21 orders and 46 genera. The dominant groups were Arcarina, Collembola. The common group were Coloptera, Lepidoptera, Diptera （L）, Geophiomorpha, Oligchaeta and so on . The research and comparison of 6 plots showed the numbers of groups and individuals in natural forest were greater , and the diversity was higher than in parallelism man-made forest; the diversity of community in the altitude of 1 850 m〉in the altitude of 1 650 m〉in the altitude of 2050 m in the nature forest , And the diversity was declining with the altitude increasing in planted forest; The ratio of individual of groups in withered and fallen layer was increasing with altitude increasing, but the results in another layers was opposite . The numbers of groups and individual in August. were greatest and the diversity in August was highest.
