2003年3月、6月和9月,对大兴安岭连续多年冻土带、岛状融区冻土带和岛状冻土带的沼泽和湿草甸土壤动物进行了调查研究。在这些沼泽和湿草甸选取了6个样地,共获得土壤动物17647只,隶属于4门8纲19目。其中,大型土壤动物的优势类群为3类,分别是线蚓科、蚁科和正蚓科,常见类群为12类;中、小型土壤动物以弹尾类和蜱螨类为最多,它们约占总个体数的92.48%,优势类群为5类,分别是中气门亚目、甲螨亚目、前气门亚目、节跳虫科和摇蚊科,常见类群有3类。
In March, June and September 2003, the marsh and wet meadow soil fauna in the continuous permafrost zone, island-shaped frozen zone and island frozen zone in the Greater Hinggan Mountains were investigated. In these swamps and wet meadows, 6 plots were selected and 17,647 soil animals were obtained, belonging to 4 classes, 8 classes and 19 orders. Among them, the dominant groups of soil macrofauna are three groups, which belong to the families Lepidoptera, Ants and Genus, respectively. The common groups are 12 species, while the most small-sized soil animals are the most abundant species of tail flies and acarina, accounting for about The number of individuals was 92.48%, and the dominant groups were 5 categories, namely, Mesocarpus, Noctuidae, Prevenulae, Arthropodidae and Chironomidae. There were 3 common groups.
