摘　　要：选取鞍山市齐大山铁矿废弃地1～6年(除3年生样地)不同生境人工林作为研究样地,2006年7月中旬对样地进行野外样品采集,捕获大型土壤动物分别隶属1门4纲9目12类。调查研究表明:铁矿废弃地大型土壤动物以蚁科为主。5种生境大型土壤动物的多样性与丰富度、均匀度呈正相关,与优势度呈负相关,与个体数没有直接的关系。从地表向下,随着土层深度的增加,不同生境土壤动物的类群多样性和个体数量逐渐减少,显示了不同生境土壤动物类群数和个体数垂直分布的明显表聚性。人为的水肥干预,能够增加土壤动物群落的多样性,大型土壤动物群落的生物多样性可以指示废弃复垦区生态系统的恢复与重建过程。The different kinds of forest land restored from the abandoned land were selected as studied areas. The soil macro-animals were sampled in July of 2006 at the Qidashan Iron Mine, Anshan, Liaoning Province. The collected soil animals were subdivided into 1 hylum, 4 classes, 9 orders and 12 categories. The results indicated that the composition of soil macro-animal community in the studied areas dominated by the Formicidae. The correlation between the diversity and richness, and between the diversity and evenness of the soil macro-animal community in five habitats was positive, but the correlation between the diversity and dominance was negative, and the diversity and individual numbers had no direct relation. With the increase of soil depth, the soil animal coummunities and individuals decreased in different habitats. Soil water and fertility levels resulted from human activities could increase diversities of soil animal communities. The effect of ecological restoration for the abandoned land could be indicated by diversity of soil macro-animals.
