Abstract: Artificial, 25-year-old Caragana korshinskii plantations in desert steppe were used to investigate the richness and biomass of ground-dwelling arthropods in cut and uncut stands, with and without reseeding. By classifying functional groups, the effects of cutting and reseeding and their interactions on ground-dwelling arthropod guilds are discussed in this study. There were five ground-dwelling arthropod guilds including phytophagous, predatory, saprophagous, necrophagous and omnivorous. The phytophagous group was the main component of ground-dwelling arthropod communities in this artificial desert steppe plantation. The management only by reseeding significantly improved the richness and biomass of the phytophagous group, while the management only by cutting considerably increased the biomass of the phytophagous group together with the richness of the predatory and omnivorous groups. Further, cutting with reseeding considerably enhanced the biomass of the phytophagous and predatory groups. It is suggested that cutting and reseeding could improve ground-dwelling arthropod guilds and the complexity of the food web, thus benefiting the effective restoration of sandy grassland ecosystems in desert steppe.
