摘  要：
选择发生外来入侵植物黄顶菊(Flaveria bidentis)的林地、荒地和沟渠作为研究对象,探讨黄顶菊入侵对地表土壤动物群落的影响。调查采用陷阱法,于2012年4月26日—9月17日,每隔2周取样一次,3种生境共捕获地表土壤动物439515头,隶属3门7纲21目。蚁科在3种生境中均为优势类群,其余类群的相对多度较小。黄顶菊植株能够为蚁科、等足目、蟋蟀科和蜘蛛目等喜好阴凉湿润环境的地表土壤动物类群提供栖息地,从而对地表土壤动物群落结构及多样性产生影响;且该影响主要与黄顶菊自身的生长状况有关,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,这在黄顶菊生长盛期尤为明显。综上所述,黄顶菊入侵3种生境后可能通过影响微生境小气候从而改变地表土壤动物群落结构,并引起地表土壤动物多样性的升高。

摘  要：
An investigation was conducted to understand the impacts of Flaveria bidentis invasion on ground-dwelling soil animal community in three different habitats( forestland,uncultivated land,and ditch). Pitfall trap was used to investigate ground-dwelling soil animals every two weeks from April 26 to September 17 in 2012. A total of 439515 individuals were collected in three habitats,belonging to 3 phyla,7 classes,and 21 orders,among which Formicidae was the dominant taxa in the community,and the relative abundance of other taxa was smaller. As the re- sult demonstrated,F. bidentis could provide habitats for Formicidae,Isopoda,Gryllidae and Araneae which like shady and moist environment,thereby had an effect on the community struc- ture and diversity of ground-dwelling soil animal community. Such impact,mainly related to growth conditions of F. bidentis,was weaker in forestland habitat but stronger in uncultivated land habitat and ditch habitat,and became more obvious during the season of growth peak for F. bidentis. In conclusion,the microclimate of three habitats might be changed and the ground- dwelling soil animal community structure was affected after the invasion of Flaveria bidentis, which increased ground-dwelling soil animal diversity.
