| 摘 要： | 2007-2008年,在铜陵狮子山尾矿库中心和边缘进行土壤动物调查,共捕得土壤动物564只,隶属4门5纲11目,其中优势类群为线虫类和蜱螨类。两大类样地土壤动物种类组成较为相似,在垂直分布上具有表聚性。对土壤动物群落进行多样性分析,得出结果,离尾矿库中心较远的样地各项指数均优于尾矿库的中心点样地;从季节动态来看,Margalef指数春季最高,夏秋缓慢降低,冬季最低。Shannon指数从春季开始缓慢增高,到秋季达到最大值,随后下降,总趋势为秋季>夏季>春季>冬季。 |

| Abstract: | During 2007 and 2008,the soil animal investigations was carried out in the center and edge of Shizishan tailings Tongling,where a total of 564 soil animals have been caught including 37 classes under 12 mesh,whose dominant groups are nematodes,mites and ticks.Two types of species composition of soil samples are similar with a table in the vertical distribution of cohesion.Through the analysis on soil animal community diversity,the outcome of the tailings is from the center of the plot far better than the index of the center of the tailings plots;from the viewpoint of the seasonal dynamic,Margalef index is the highest in spring,summer and fall slowly decreased,the lowest in winter.Shannon index increases slowly from spring to autumn maximum,then decreases,with the general trend of the autumn summer spring winter. |
