【摘要】 为了探究大亮子河林场不同林型土壤节肢动物的群落结构特征及多样性，选取5种不同林型为研究对象，用Tullgren干漏斗法对土壤节肢动物进行分离，对捕获的节肢动物进行数量统计，经分析得到其群落结构特征及多样性相关数据。本次调查共捕获到节肢动物2 457只，隶属于5纲10目43科，优势类群为棘跳科和等节跳科，分别占采集总个体数的11.56%和11.15%。针阔混交林的Shannon-Wiener多样性指数最高，但Simpson优势度指数最低。5种林型采样点中的土壤节肢动物垂直分布特征具有明显的表聚性。该研究将为环境评估以及森林和保护区的生态保护提供理论支持。更多还原

【Abstract】 In order to explore the community structure characteristics and diversity of soil arthropods in different types of forests in Daliangzihe Forest Farm, the soil in 5 different types of forests was selected as the research object, and the soil arthropods were separated by Tullgren dry funnel method. The number of captured arthropods was counted, and the data of community structure characteristics and diversity were obtained by analysis. In this survey, a total of 2 457 arthropods those belonged to 5 classes, 10 orders, and 43 families were captured. The dominant groups were Onychiuridae and Isotomidae, accounting for 11.56 % and 11.15 % of the total number, respectively. The Shannon-Wiener diversity index of coniferous and broad-leaved mixed forests was the maximum, while its Simpson dominance index was the minimum. The vertical distribution characteristics of soil arthropods in the sampling points of 5 different types of forests had obvious surface aggregation. This research provided theoretical support for environmental assessment and ecological protection of forests and protected areas.更多还原
