摘要
文章通过对黄土高原丘陵区刺槐林-草地复合系统景观边界上3种景观位置的土壤表层大型动物调查、分析,结果表明:复合系统共有大型土壤动物16类,隶属于3门6纲;林缘处是土壤表层大型动物多样性最高的地方,这里土壤动物群落较复杂,类群数较多,分布均匀;草地是土壤表层大型动物多样性最低的地方,这里土壤动物群落较单一,土壤动物类群数偏少,个体数偏多,分布的均匀性较差,优势类群表现突出;林地的土壤表层大型动物多样性介于二者之间。林缘与林地内土壤动物的分布特征相似性较大,林缘与草地内土壤动物的分布特征相似性较小。
In this paper, surveys and analysis d large animals in top soil layers on 3 locations on scenic borders of Robinia forests and grasslands systems in Loess hilly areas were conducted. The results indicated that there were 16 kinds of large soll animals generally in the compound systems, which belonged to 3 phyh and 6 classes; forest homers were places where diversity of large animals in top soil layers was highest and communities of soil animals were complicated, number d species was rich and distributed evenly;grasslands were places where diversity of large animals in top soll layers was lowest and commnities of soll animals were singularity ; number of species was fewer and individuals were rich and distributed unevenly, and dominant species behaved outstandingly; diversity of large animals in top soil layers on forest landwas between that for forest borders and grassland, Comparability of distribution characterizes for soft animals on borders and in forests was great, and comparability of distribution characteristics for soft animals on borders and in grasslands was small.
