中文摘要	以荒漠草原区25年龄人工柠条林为研究对象,调查了未平茬未补播(对照)、非平茬补播、平茬非补播与平茬兼补播处理柠条林地中地面节肢动物类群数和生物量,结合功能群划分,分析了柠条平茬和林带间补播牧草及其交互作用对柠条林地地面节肢动物功能群分布的影响。结果表明,调查样地共捕获地面节肢动物11目31科34个类群,划分为5种不同营养功能群:植食性、捕食性、腐食性、尸食性和杂食性,其中植食性动物是荒漠草原区人工柠条林地地面节肢动物区系的主要组成部分。非平茬补播处理可以显著增加植食性动物的生物量(P<0.05);平茬非补播处理可以显著增加植食性动物的生物量(P<0.05)、捕食性(P<0.05)和杂食性动物的类群数(P<0.01);平茬兼补播处理显著提高植食性和捕食性动物的生物量(P<0.05)。研究表明,荒漠草原区对柠条林地进行平茬和补播可以丰富地面节肢动物功能群数量和提高食物网的复杂性,有利于促进沙化草地生态系统有效恢复。
英文摘要	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.
