摘　　要：建植人工灌丛可以防风固沙,有利于生态恢复,但不同灌丛建植模式对地表节肢动物的影响不同。选择带状和点状两种排列方式的柠条锦鸡儿灌丛为研究对象,通过陷阱诱捕法捕获地表节肢动物,并调查其群落组成、多样性特征和功能群结构,以探究灌丛不同排列方式对地表节肢动物的影响。结果表明:(1)优势类群的类群数在5、7月份表现为带状显著低于点状(P<0.05),常见类群的个体数和类群数在5、10月份表现为带状显著高于点状(P<0.05),稀有类群的个体数和类群数在7、10月份表现为带状显著高于点状(P<0.05)。(2)地表节肢动物个体数在10月份表现为带状显著高于点状(P<0.05);类群数在5、7、10月份表现为带状显著高于点状(P<0.05);Shannon-Wienner多样性指数在5、10月份表现为带状显著高于点状(P<0.01);Simpson优势度指数在5月份表现为带状显著低于点状(P<0.01)。(3)捕食性个体数在5、7月份表现为带状显著低于点状(P<0.05);植食性个体数在5、7月份表现为带状显著高于点状(P<0.05);杂食性个体数在10月份表现为带状显著高于点状(P<0.001);其他食性个体数在5月份表现为带状显著高于点状(P<0.05)。捕食性类群数在5月份表现为带状显著低于点状(P<0.01);植食性类群数在5、7、10月份表现为带状显著高于点状(P<0.001);杂食性类群数在5、10月份表现为带状显著高于点状(P<0.01),而在7月份表现为带状显著低于点状(P<0.01);其他食性类群数在5月份表现为带状显著高于点状(P<0.05)。(4)土壤容重、pH和草本丰富度是影响不同排列灌丛间地表节肢动物群落结构分布差异的主要环境因子。综上,带状排列灌丛更利于地表节肢动物的生存和定居,从而维持地表节肢动物食物网结构和系统的相对稳定性。Artificial shrub planting helps prevent wind erosion and sand encroachment,beneficial for ecological restoration efforts.However,varying shrub planting patterns exert distinct impacts on ground⁃active arthropod populations.Two planting arrangements of the Caragana koraiensis shrub⁃belt and point⁃were selected to reveal the impacts of ground⁃active arthropods on community composition,diversity,and functional group structure by the trap trapping method.The results showed that:(1)the richness of the dominant group in May and July was significantly reduced in the belt than in the point(P<0.05),while the individual number and group richness of the common group in May and October was significantly higher in the belt than in the point(P<0.05),the individual number and group richness of the rare group in July and October was significantly higher in the belt than in the point(P<0.05).(2)In October the individual number of ground⁃active arthropods was significantly higher in the belt than in the point,the group richness in May,July and October was significantly higher in the belt than in the point(P<0.05),the Shannon⁃Wienner diversity index in May and October was significantly higher in the belt than in the point(P<0.01),while the Simpson dominance index in May was significantly lower in the belt than in the point(P<0.01).(3)The Individual number of predatory in May and July was significantly lower in the belt than in the point(P<0.05)the Individual number of phytophagous in May and July was significantly higher in the belt than in the point(P<0.05).In October,the individual number of omnivorous was significantly higher in the belt than in the point(P<0.05),the Individual number of other feeding habits(saprozoic,parasitic,and fungivorous)in May were significantly higher in the belt than in the point(P<0.05).The group richness of predatory in May was significantly lower in the belt than in the point(P<0.01),the group richness of phytophagous in May,July and October was significantly higher in the belt than in th
