| In order to explore the effects of Aluminum on large and medium-sized soil animals in litter layer, a simulation experiment was conducted and sample areas were set up from November 2012 to October 2013 in artificial forest of Schima superb. Through spraying different concentrations of Aluminum and after eight times sampling, the result showed that, the effects of Aluminum on the number of soil animals and number of soil animal groups were not significant.Dominant groups like Oribatida and Collembola were not sensitive to Aluminum treatment, while some common groups were affected significantly, the number of Mesostigmata and Coleoptera decreased with the increase of Aluminum concentration,so they could be the indicating groups. Sampling period had significant effect on the number of soil animals and groups.Aluminum had more obvious effect on soil animal community in the season with less animals. The treatment of Aluminum solution reduced the level of diversity of soil animal community, and was not good to the establishment of micro ecological environment of plant. |
