摘要
2010年6~7月,对拉鲁湿地5个生境的土壤动物进行了调查,共捕获大型和中小型干生土壤动物41类,18 446只,隶属于3门7纲14目32科17属。土壤动物的优势类群为线蚓科,占总捕获量的10.95%。常见类群有27类,占总捕获量的84.63%,其中螨类占总捕获量的32.5%,弹尾类占总捕获量的31.43%。各生境的土壤动物数量和种类在土壤各层的垂直分布具有明显的表聚性。5个生境分布的土壤动物Shannon-Weiner多样性指数(H')从大到小依次为3#>5#>4#>1#>2#。5个生境间土壤动物的相似程度由极不相似到中等不相似(S值为0.105~0.400)。
Macro-and mid-soil animal was sampled from five quadrates(20 m×20 m each) to presented the soil community of Lhalu Wetlands in June and July 2010 of the study area.Total of 18 446 species,belonging to 3 phyla,7 classes,14 orders,32 families and 17 genera were recorded.Individuals belonged to Enchytraeidae was dominant and accounted for 10.95% of the total sampled specimen.About 84.63% of the total individuals were the component of 27 groups(family or genus) which are considered common groups.Among those common group,Acari and Collembola accounted for 32.5% and 31.43% of sampled individuals.The soil animals mainly distributed in the soil surface layer in the sampled quadrates.The value of diversity index H′ in each samples from highest to lowest was in the order 3#5#4#1#2#.The species similarity among the 5 samples were either medium or extreme dissimilarity(S was 0.105-0.400),respectively.
