中文摘要	湖泊湿地是干旱区重要的生境类型,在维持陆生节肢动物多样性方面起着重要的作用。选择黑河中游典型湖泊湿地及毗邻沙丘作为研究区,监测了湿地、过渡区和沙丘生境地表节肢动物种类组成及数量变化。结果表明:(1)湿地、过渡区和沙丘生境地表节肢动物群落组成明显不同,湿地生境地表节肢动物活动密度、类群丰富度和多样性指数均显著高于沙丘生境,过渡区生境地表节肢动物类群丰富度和多样性指数显著高于沙丘生境;(2)湿地、过渡区和沙丘生境捕食性、植食性和"腐 +杂"食性节肢动物组成明显不同,从湿地到沙丘,捕食性和植食性节肢动物活动及类群丰富度呈降低的趋势,而"腐+杂"食性节肢动物类群丰富度变化相反;( 3)地表节肢动物对3种生境有较好的指示作用,狼蛛科(Lycosidae)、步甲科(Carabidae)和虎甲科(Cicindelidae)等7个类群可以用于指示湿地生境,谷盗科(Trgossitidae)和拟步甲科(Tenebrionidae)分别可以指示过渡区和沙丘生境。总之,干旱区湿地生境对狼蛛科、步甲科和虎甲科等一些节肢动物种群有明显的保育作用,它对这些地表节肢动物类群的保护及维持具有重要的生态意义。
英文摘要	Lake wetland was an important habitat type in the Heihe River Basin,and its play a key role in maintaining terrestrial arthropods diversity.However,our understanding of the effect of lake wetland on arthropod diversity in this region is poor,especially on ground-dwelling arthropods.We select a typical lake wetland and the adjacent sand dune as a research region in the Middle Reaches of the Heihe River basin.We explored the abundance and species richness of ground arthropods using pitfall trapping at the three habitats(wetland,transitional zone and sand dune)in the mid-July.Three key results were obtained as following.(1)The community composition of ground-dwelling arthropods in wetland,transitional area and dune habitat is significantly different.Further, the activity density,taxa richness and diversity index of ground-dwelling arthropods in wetland habitats are significantly higher than those in sand dune habitat,and the taxa richness and diversity index of ground-dwelling arthropods in transitional zone are significantly higher than those in sand dune habitats.(2)The composition of predatory,herbivorous and"saprophagous + omnivorous"ground-dwelling arthropods in wetland,transitional area and dune habitat is obviously different.From wetland to sand dune,the activity and richness of predatory and herbivorous ground-dwelling arthropods are decreasing,while the richness of"saprophagous + omnivorous" ground-dwelling arthropods is changing in the opposite pattern.(3)A strong indication of ground-dwelling arthropods for habitat type was discovered in this ecosystem.Moreover,seven taxa including lycosid spiders,carabid and cicindelid beetles can be used as indicator taxa for wetland habitats,and trgossitid and tenebrionid beetles and can be used as indicator taxa for transitional zone and sand dune habitats.In short,wetland habitat in arid area has obvious conservation affect on some ground-dwelling arthropods,such as lycosid spiders and carabid and cicindelid beetles.It has important ecological significance for the protection and maintenance of these ground-dwelling arthropods.
