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 anthropogenic plantations of different habitats from 1 year to 6 years (excluding 3-year-old plots) of Anshan Qidashan Iron Mine were selected as research plots. In the middle of July 2006, samples were collected from the plots to capture large soil fauna, 4 classes 9 head 12 categories. Investigation shows that: large-scale soil fauna in abandoned iron mines is dominated by ant families. The diversity, abundance and evenness of the soil macrofauna in five habitats were positively correlated, negatively correlated with the dominance, and not directly related to the individuals. From the surface to the bottom, with the increase of soil depth, the taxonomic diversity and individuals number of soil fauna in different habitats gradually decreased, indicating the obvious epicontinental distribution of soil fauna and individuals in different habitats. Man-made water and fertilizer interventions can increase the diversity of soil animal communities, and the biodiversity of large soil animal communities can indicate the process of ecosystem restoration and reconstruction in abandoned reclamation areas.
