摘  要：
采用陷阱法在地表节肢动物活动高峰期(7—8月)对辽东山区蒙古栎(Quercus mongolica)林、胡桃楸(Juglans mandshurica)林和阔叶混交林3种次生林以及红松(Pinus koraiensis)人工林和落叶松(Larix spp.)人工林地表节肢动物群落进行了调查。共捕获地表节肢动物5135头,隶属于7纲18目66个类群,优势类群为蚁科(20.4%)、葬甲科(19.5%)、蜣螂科(17.2%)和步甲科(14.5%);地表节肢动物的功能群丰度依次为:腐食性>杂食性>捕食性>植食性;系统聚类分析表明,地表节肢动物群落和地表甲虫群落均显示红松人工林、落叶松人工林和胡桃楸林群落结构聚为一类,蒙古栎林和阔叶混交林群落聚为一类;冗余度分析表明,凋落物厚度、植被盖度与树高因子可以解释地表节肢动物及地表甲虫群落差异的85.9%和81.9%。研究结果表明,研究区森林植被及凋落物状况、人为干扰是影响研究区大型地表节肢动物群落多样性的重要因素。

摘  要：
Using the pitfall trapping method,the ground-dwelling arthropod communities were investigated in three types of secondary forests( Quercus mongolica,Juglans mandshurica,and broad-leaved mixed forest) and two types of plantation forests( Pinus koraiensis and Larix spp.)in a montane region of eastern Liaoning Province during the active time from July to August. A total of 5135 individuals of ground-dwelling arthropods were collected,belonging to 7 classes,18 orders,and 66 groups. Formicidae( 20.4%),Silphidae( 19.5%),Scarabaeidae( 17.2%) and Carabidae( 14.5%) were the dominant taxa. The abundance of the functional groups was ranked as saprozoic > omnivore > predator > phytophage. According to the system clustering analysis,P.koraiensis plantation forest,Larix spp. plantation forest and J. mandshurica forest were grouped together; Q. mongolica forest and the broad-leaved mixed forest were clustered into one group.Based on the redundancy analysis( RDA),litter depth,vegetation cover and tree height could explain 85.9% and 81.9% of community distribution variation of ground-dwelling arthropods and beetles,respectively. This study indicated that forest vegetation and litter distribution,and human disturbance in the study region were the key factors influencing the diversity of macro ground-dwelling arthropod community.
