大型土壤动物在鞍山市大孤山铁矿废弃地生态环境恢复与重建中的指示作用

对鞍山市大孤山铁矿废弃地大型土壤动物的生态特征进行了调查，分析研究铁矿废弃地自然生态环境的演化和大型土壤动物群落变化的关系，在大孤山铁矿废弃地生态环境恢复与重建中大型土壤动物具有重要的指示作用。大型土壤动物种类、数量变化标志大孤山铁矿废弃地生态环境恢复与重建阶段先后；大型土壤动物群落生态结构与生物量的变化指示铁矿废弃地生态环境恢复与重建质量；蚁科与腹足纲是大孤山铁矿废弃地生态环境恢复与重建的重要指示物种。

LARGE SOIL ANIMALS INDICATOR FUNCTIONS OF RECLAMATION OF ECOLOGICAL ERVIRONMENT IN IRON-MINE ABANDONED OF DAGUSHAN, ANSHAN CITY

The relationships between ecological environment evolution of i ron-mine abandoned and community variety of large soil animals were studied thro ugh the investigation of abandoning mine in Da-gushan, Anshan city, which point s out that large soil animals have the important indicator functions to the recl amation of ecological environment for the abandoning iron-mine. Some valuable co nclusions were shown in this paper. Large soil animals are important sign for st ages of the reclamation of ecological environment of mine abandoned. The runnin g trend of quantity and categories of large soil animals mark the phrase of recl amation of mineral remains. The changing of ecological structure and biomass of large soil animals community expose the degree of reclamation of mine abandoned. Castropoda and Formicidae are two important indicators, which tell us about the reclamation of iron-mine abandoned in Da-gushan of Anshan city.
