中文摘要	为了解固沙灌丛林营造对地面节肢动物群落组成及多样性的影响,选择扎设草方格后营造的油蒿(Artemisia ordosica)、花棒(Hedysarum scoparium)、沙拐枣(Calligonum mongolicum)和柠条(Caragana korshinskii)灌丛林地为研究对象,以流动沙地为对照,采用陷阱诱捕法调查了不同生境样地地面节肢动物群落组成、多样性与生物量分布及其功能群结构特征。结果显示:(1)相对于流动沙地,油蒿、花棒和柠条林的地面节肢动物群落组成均表现为优势类群和常见类群的类群数变化不大,但稀有类群的类群数有所增加,而且优势类群和稀有类群的优势度增加,常见类群的优势度下降。沙拐枣林地表现为无稀有类群出现。(2)地面节肢动物个体数、类群数和Shann on指数均表现为油蒿林地显著高于流动沙地(P<0.05),而其余3个林地与流动沙地间无显著差异性。生物量则表现为油蒿林地显著低于流动沙地和花棒、沙拐枣和柠条林地(P<0.05)。(3)捕食性和腐食性动物类群的个体数和类群数均表现为油蒿最高,而其余3个林地与流动沙地间无显著差异性。但是,植食性动物类群的个体数则表现为花棒最高,而其余3个林地与流动沙地间无显著差异性。(4)草本植物多度(F=6.91,P=0.001)对地面节肢动物多度分布产生显著影响。灌丛林营造短期内,油蒿灌丛林对地面节肢动物多样性的保育效应要优于其他灌丛林地,而且油蒿、沙拐枣、花棒和柠条等植物短期恢复对地表节肢动物群落组成及营养结构的影响不同。
英文摘要	The aim of present study was to probe into the effect of afforested plantations in terms of shrub species on ground-active arthropod communities in shifting sand land.The Artemisia ordosica,Hedysarum scoparium,Caragana korshinskii,and Calligonum mongolicum shrubs were selected as afforested subjects within straw checkboard,with the adjacent shifting sand land as a control.An investigation on ground-active arthropod community composition,diversity and trophic structure were carried on by the method of pitfall trapping.All the results were shown that:(1)Relative to the control,there was little change of number of taxonomic groups of dominant groups and common groups observed in A.ordosica,H.scoparium,and C.korshinskii plantations,while the number of rare groups increased remarkably.This point was reverse to the that observed in C.mongolicum plantations where no individuals of rare groups were captured.(2)The abundance,richness and Shannon index of ground-active arthropods were found to be significantly greater in A.ordosica plantations compared with the other three plantations.The biomass of ground-active arthropods was found to be significantly lower in A.ordosica plantations compared with the other three plantations.(3)There were four trophic groups observed including predator,phytophaga,saprophage,and omnivores.The abundance and richness of predator and saprophages were found to be highest in A.ordosica plantations compared with the other habitats.However,the abundance of phytophaga were found to be highest in H.scoparium plantations compared with the other habitats.(4)The abundance of herbaceous plants,soil pH and shrub canopy were the key factors driving the distribution of ground-active arthropod communities between the shifting sand land afforested by different shrub species.It was suggested that there was facilitative effect of A.ordosica plantations on ground-active arthropod diversity as well as the abundance and richness of predator and saprophages relative to the other three shrub plantations.In addition,there was a conducive effect of H.scoparium plantations on the abundances of phytophaga.Furthermore,there was limited effectiveness of single pure shrub afforestation on biodiversity conservation,while it was suggested that the mixed shrub afforestation played implications on the stability of afforested vegetation on desertification control.
