中文摘要	以荒漠草原区25年龄柠条林为研究对象,通过调查未平茬未补播、补播、平茬和既平茬又补播牧草的柠条林地中地面节肢动物群落特征,分析了补播和平茬及其交互作用对柠条林间和林下地面节肢动物个体数和类群数分布的影响.结果表明:在未平茬未补播牧草的林地中,林间地面节肢动物个体数和类群数均显著低于林下.与未平茬未补播牧草林地相比,补播、平茬和既平茬又补播牧草均显著增加柠条林间地面节肢动物个体数和类群数,而对柠条林下地面节肢动物个体数和类群数分布无显著影响,经过不同管理措施处理后,柠条林下与林间的地面节肢动物分布无显著差异.平茬和补播对柠条灌丛内外地面节肢动物分布影响具有类同效应,而且相互之间存在缓冲作用,补播与平茬处理、平茬与既平茬又补播处理、补播与既平茬又补播处理之间,林间和林下地面节肢动物的分布均无显著差异.在荒漠草原区柠条人工林中,平茬、补播和既平茬又补播牧草均可以显著提高柠条林地特别是林间地面节肢动物多样性,有利于退化草地生物多样性保护、生态系统恢复和柠条人工林的有效管理.
英文摘要	Taking a 25-year-old Caragana intermedia forest in desert steppe as test object,an investigation was conducted on the ground-dwelling arthropod community in cutting and no-cutting stands with and without reseeding,aimed to understand the effects of cutting,reseeding and their interaction on the individual number and group richness of ground-dwelling arthropod in C.intermedia forest.There were significantly lower number and richness of ground-dwelling arthropod in the open spaces than under the shrubs in the no-cutting and no-reseeding stands.Cutting,reseeding and both of them could significantly increase the number and richness of ground-dwelling arthropod in the open spaces,but not under the shrubs,compared with no cutting or reseeding.Consequently, there were no significant differences in the distribution of ground-dwelling arthropod in the open spaces and under the shrubs in the cutting,reseeding,or cutting and reseeding stands.Further, there was a similar buffer effect between cutting and reseeding on the ground-dwelling arthropod.No significant differences were observed in the ground-dwelling arthropod distribution,between cutting stand and reseeding stand,between cutting stand and cutting and reseeding stand,and between reseeding stand and cutting and reseeding stand.It was suggested that cutting,reseeding,or both of them could significantly improve the ground-dwelling arthropod diversity especially in the open spaces,being beneficial for the restoration of degraded grassland ecosystem and the rational management on artificial C.intermedia forest in desert steppe.
