摘要: 为研究紫茎泽兰(Eupatorium adenophorum Spreng)入侵前后对不同生境土壤动物群落的影响,对文山老君山国家级自然保护区草地、杉树林、阔叶林和竹林4种生境在紫茎泽兰入侵前后的土壤动物进行调查分析。结果表明,在各样地共采集到土壤动物标本11 116头,隶属2门6纲14目41科,其中,优势类群为颤蚓目(Tubificida)、真螨目(Acariformes)、寄螨目(Parasiformes)、弹尾目(Collembola)和膜翅目(Hymenoptera)。不同生境土壤动物各多样性指数都是紫茎泽兰入侵小于未入侵,表明入侵后物种丰富程度、同类动物获得概率、物种多样性程度、个体数目分配的均匀程度都表现为下降的趋势;紫茎泽兰入侵前后,除阔叶林土壤动物各多样性指数都没有显著差异外,其他3种生境都有部分多样性指数存在显著差异(P<0.05)。

Abstract: In order to study the effects of Eupatorium adenophorum Spreng on soil animal communities of different habitats, soil animals of grassland, cedar forest, broad-leaved forest and bamboo forest were investigated and analyzed in Laojunshan National Nature Reserve, Wenshan. The results showed, 11 116 soil animal specimens were collected in various places, belonging to 2 phyla, 6 classes, 14 orders and 41 families. The dominant menoptera groups were Tubificida, Acariformes, Parasiformes, Collembola and Hymenoptera. The values of various diversity indexes of soil animals in different habitats after the invasion of Eupatorium adenophorum Spreng were less than those of non invasion, indicating that the species richness, acquisition probability of the same species, species diversity and evenness of individual number distribution all showed a downward trend after the invasion. Except for broad-leaved forest, some diversity indexes of the other three habitats between invasion and non invasion showed significant differences in the four diversity indexes(P<0.05).
