摘要
在三江平原湿地选择森林、湿地、农田、退耕林地、退耕湿地五种土地利用方式,对其大型土壤动物的群落结构和多样性特征进行研究。共获得大型土壤动物2566只,隶属3门6纲16个类群,分析了大型土壤动物种类组成、数量分布及多样性。从总体上看,优势类群为鞘翅目、蜘蛛目和正蚓目,常见类群为地蜈蚣目、鞘翅目幼虫、石蜈蚣目、倍足类、双翅目幼虫、盲蛛目和直翅目。不同土地利用方式大型土壤动物类群数差异不大,个体数退耕湿地>湿地>退耕林地>森林>农田。大型土壤动物群落多样性各指数的分析表明,群落多样性与均匀度呈正相关,群落内物种分布越均匀,则优势度越小。
The community structure and diversity of soil macrofauna were researched in5different utilized land in Sanjiang plain wetland.The5typical plots were forest、wetland、farmland、forest returned from farmland and wetland returned from farmland2566individuals were obtained in total,belonged to3phyla6Class16Groups.The species composition,quantity distribution and diversity of soil macrofauna were analyzed.In general,the dominant groups were Coleoptera、Araneaeand Lumbricida.The common groups were Geophilomorpha、Coleoptera larvae、Lithobiomorpha、Diplopoda、Diptera larvae、Opiliones and Orthoptera.There was no significant difference in soil macrofauna groups in different land use,the number of individuals was wetland returned from farmland>wetland>forest returned from farmland>forest>farmland.Theanalysis of diversity index of soil macrofauna community showed,community diversity was positively correlated with evenness.The more uniform the species distribution in the community,the smaller the dominance.
