摘要
对贵州中部喀斯特石灰岩地区3种植被(草本,灌丛,乔木)下的大型土壤动物群落进行研究,选用类群数、个体数、密度以及多样性、均匀性、优势度指标来反映土壤动物群落结构。结果表明:黔中喀斯特石灰岩地区生态系统中,优势类群为寡毛纲和蚁科2类,稀有类群为腹足纲、蜈蚣目、伪蝎目、等足目、综合纲、双尾目、弹尾目、等翅目、蟋蟀总科、革翅目、半翅目、双翅目(幼虫)和蝉科(幼虫)共13类;优势类群代表了适应大环境条件的土壤动物的主体,是喀斯特石灰岩地区的代表性类群;不同植被类型和生境对土壤动物群落的组成和数量具有较大的影响;蚂蚁在喀斯特石灰岩地区灌丛分布最广,蚂蚁群落对灌丛植被恢复起到关键性作用;蚁科在黔中喀斯特石炭岩地区种群数量的变化,显示黔中喀斯特地区生态环境特征的重要转变;寡毛纲在黔中喀斯特地区种群数量的变化和生物量的大小,可指示黔中喀斯特地区生态系统恢复与重建程度。
The soil macrofauna communitie under three vegetation （grass, shrubs, trees）in the karst limestone region in central Guizhou were studied, and a few selected groups, individual number, density and diversity, homogeneity, dominance indicators to reflect the community structure of soil farina. The results showed that karst limestone region＇s ecological system in Guizhou, the predominant group there Oligochaeta and Formicidae 2 category, Gastropoda, Scolopendromorpha, Pseudoscorpiones, Isopoda, Symphyla, Diplura, Collembola, Isoptera, Grylloidea, Deramptera, Hemiptera, Diptera （larvae） and Cicadidae （larvae） a total of 13 categories for rare taxa. Advantages group represents adapt to the larger environment of the main soil animals, karst limestone region is the representation of groups; different vegetation types and habitats on the composition of the soil and animal communities a larger number of the impact of ants in the karst limestone region shrub most widely distributed, ant communities on the shrub vegetation restoration has played a key role; Formicidae in the karst limestone region in central Guizhou number of the changes that show that the ecological environment of karst in Guizhou characteristics of the major changes. Oligochaeta in karst region in central Guizhou changes in number and biomass, may direct the karst region in central Guizhou ecosystem restoration and reconstruction degree.
