中文摘要	调查不同植被恢复措施下拉萨半干旱河谷地表节肢动物类群多样性以及群落结构,为揭示地表节肢动物多样性对植被恢复措施的响应具有重要意义。采用陷阱法对青藏高原半干旱河谷砂生槐灌丛、人工杨树林和藏沙蒿灌丛样地地表节肢动物群落组成、类群多样性以及功能群结构进行调查,计算各处理地表节肢动物类群相对多度、类群丰富度、多样性指数、Cody指数和Sorensen指数。共采集半干旱河谷地表节肢动物个体数738,隶属5纲15目51科。砂生槐灌丛样地收集节肢动物40科,占所有类群78.4%,杨树人工林和藏沙蒿灌丛样地调查到土壤节肢动物类群为30和23科,分别占总科数的58.8%和45.1%。各植被恢复类型在目的分类单元下,双翅目、膜翅目和弹尾目类群相对多度较高,而在科的分类单元下,驼跳科、蚁科和漏斗网蛛科为拉萨半干旱河谷优势地表节肢动物类群。砂生槐灌丛节肢动物类群丰富度和多样性指数最高,人工杨树林最低。砂生槐灌丛和藏沙蒿灌丛地表节肢动物营养功能群均以捕食性为主。不同植被群落间群落相似性也有差异,砂生槐与藏沙蒿灌丛间相似性较高,而人工杨树林与藏沙蒿之间较低。不同植物群落组成和结构影响土壤理化特性、地表凋落物数量、质量和微生境条件,进而影响地表节肢动物群落组成、数量和营养功能群。砂生槐灌丛样地具有较高节肢动物类群丰富度和捕食性动物类群,有利于拉萨半干旱河谷地区地表节肢动物多样性维护。
英文摘要	The diversity and trophic functional group of ground-dwelling arthropod communities was investigated in the Lhasa semi-arid valley in China in order to provide further insight in our understanding of the response of arthropod diversity to vegetation restoration.The study was carried out in three vegetation types including Sophora moorcroftiana(SM),Populus spp.(PS),and Artemisia wellbyi(AW).The pitfall trap method was used to investigate the community composition,diversity,and functional group structure by calculating the relative abundance,richness,Shannon-Wiener diversity index,Pielou evenness index,Simpson dominant index,Cody index,and Sorensen index of ground-dwelling arthropods.A total of 738 individuals were collected,representing 5 insects,15 orders,and 51 families.There were 40,30,and 23 families under SM,PS,and AW,accounting for 78.4%,58.8%,and 45.1% of the total fauna,respectively.The relative abundance of Diptera,Hymenoptera,and Collembola were the higher in the taxonomy of the order,and Cyphoderidae,Formicidae and Agelenidae were the dominant group in the taxonomy of the family in the three vegetation restoration measures.The largest values of richness and diversity were found under SM,while the lowest under PS.The analysis of similarities of arthropod community indicated the similarities of ground-dwelling arthropod fauna varied among different vegetation types,with the highest similarity between SM and AW and the lowest similarity between PS and AW.The results of this study demonstrate that the composition and structure of vegetation community affect soil physical-chemical properties,amount and quality of ground litter,and micro-environment condition,thus affecting the community composition,population,and functional group of arthropods.SM has higher abundance of arthropod group and predatory group,which contributes to conserving arthropod diversity of land in the Lhasa semi-arid valley.
