以黄顶菊(Flaveria bidentis)入侵的林地、荒地和沟渠作为调查样地,探讨黄顶菊凋落物对土壤无脊椎动物群落的影响。利用环刀进行取样,3种生境共捕获土壤无脊椎动物54315头,隶属2门10纲17目。3种生境的优势类群皆为蜱螨目和弹尾目,其余类群的相对多度较小。黄顶菊凋落物能够为土壤无脊椎动物提供栖息地与食物来源,进而影响其群落结构及多样性,该影响与黄顶菊自身群体的生长状况有关,在长势较弱的林地生境影响较小,而在长势较强的荒地和沟渠生境影响较大。综上所述,黄顶菊入侵3种生境后,植株及其凋落物能为优势类群提供更好的栖息地和隐蔽所,并通过改变表层腐殖土的主要养分含量,引起土壤无脊椎动物多样性的升高,且土壤无脊椎动物在凋落物层中多样性呈自上而下的升高趋势。 An investigation was conducted to explore the impacts of Flaveria bidentis litter on the communities of invertebrates in soil in three different habitats including forestland, wasteland, and ditches. A total of 54315 individuals were captured in three habitats on October 23rd by cutting ring(diameter is 20 cm, height is 10 cm), which is divided into three sampling layers in this study. All of the individuals belong to 2 phyla 10 classes 17 orders, among which Arachnoidea and Collembola were the dominant orders in three habitats, and the relative abundance of other species were smaller. F. bidentis litter could provide the better habitats and food sources for invertebrates in soil,
