【摘要】 为揭示煤矸石山复垦后大型土壤动物群落特征,于2016年9月对霍州煤矸石山4个样地(油葵、草地、桃树、对照)的大型土壤动物进行了调查。结果表明:霍州煤矸石山大型土壤动物优势类群为蚁科和弹尾目,土壤动物个体密度和类群数的水平分布表现分别为桃树>油葵>草地>对照、对照>桃树>油葵>草地,其中桃树地土壤动物密度与其他样地有显著差异;土壤动物在垂直方向上分布具有表聚性特征,但是各层次间无显著差异;对照样地土壤动物多样性高于煤矸山样地;大型土壤动物群落Jaccard相似性系数基本集中在0. 5左右,为中等相似。土壤动物密度和类群数与土壤p H值呈显著负相关,与土壤含水量、有机质、全磷及全钾则没有显著的相关性。研究结果可为煤矸石山的修复治理提供土壤动物生态学依据。更多还原

【Abstract】 In order to investigate the characteristics of soil macrofauna community in Huozhou coal waste pile,in the beginning of September 2016,the effects of plots( oil sunflower,grassland,peach and corn fileds) on Huozhou coal waste pile soil macro-fauna were investigated.The results showed that the dominant species are Formicidae and Collebola,accounting for 83.79% of the total.The peach field is significantly different from other plots.There is no significant difference in vertical distribution of soil fauna.The soil fauna diversity in the control land is higher than other plots in Huozhou coal waste pile.The Jaccard similarity coefficients of the soil macro-faunal community are about 0.5,belonging to medium.The results can provide the ecological basis of soil fauna for the restoration and treatment of coal waste pile.更多还原
