| 摘 要： | 薇甘菊是菊科假泽兰属的恶性杂草,在我国华南地区已成功入侵并造成严重危害.为了解薇甘菊入侵对土壤动物的影响效应,采用野外样地试验法对广州市火炉山森林公园薇甘菊入侵群落的土壤动物进行了调查.2009年4次采样共获得中小型土壤动物5206头,隶属于4门10纲19类,其中线虫类为优势类群,蜱螨目、弹尾目和轮虫是常见类群.薇甘菊入侵地中小型土壤动物群落结构特征发生了改变,与其他样区相比,入侵区中小型土壤动物的总个体数以及线虫类、蜱螨目的个体数显著增加,但中小型土壤动物类群数的变化不明显;在群落多样性方面,薇甘菊入侵区土壤动物群落的密度-类群指数显著提高,物种丰富度、优势度指数亦有所上升,但差异不明显,而均匀度、Shannon指数趋于下降;在群落相似性方面,薇甘菊入侵区与群落交错区的相似程度较高,与土著植物区的相似程度较低.薇甘菊入侵所引起的局部气候环境、凋落物、根系分泌物与土壤理化性质的变化可能是造成中小型土壤动物群落结构特征改变的主要原因.

| Abstract: | Mikania micrantha,a notorious exotic weed of Asteraceae family,has invaded successfully in southern China,and caused serious damages to native ecosystems.In this paper,a field survey was conducted in the Huolushan Forest Park of Guangzhou,China,aimed to understand the impact of M.micrantha invasion on the soil meso-and micro-invertebrate community.Three sampling sites were installed,including M.micrantha-invaded site,ecotone,and native vegetation site.Through four samplings in 2009,a total of 5206 soil meso... |
