中文摘要	以中国科学院奈曼沙漠化研究站为依托,对不同放牧强度后自然恢复沙质草地土壤节肢动物群落进行了调查,分析了土壤节肢动物群落结构及其多样性变化,探讨了植被和土壤环境对土壤节肢动物群落的影响.结果表明:无牧草地土壤动物种类丰富,个体数量较多,多样性最高;中牧后恢复草地土壤动物个体数量少,但主要类群较多,分布较均匀,多样性较高;重牧后恢复草地土壤动物主要类群少,但个体数量多,多样性较高;而轻牧后恢复草地土壤动物分布均匀性最差,多样性最低.植物个体数,高度及盖度和土壤酸碱度是影响不同放牧强度后恢复草地土壤动物种类和个体数量分布的主要因素.说明沙质草地经过12年的围封可以一定程度上恢复土壤动物群落,而放牧干扰对土壤动物群落的负面影响是长期的
英文摘要	Taking the Naiman Desertification Research Station under Chinese Academy of Sciences as a base,an investigation was conducted on the community structure of soil arthropods in the naturally restored sandy grasslands after different intensity grazing disturbance, with the effects of vegetation and soil on this community structure approached. In the non-grazing grassland, soil arthropods were rich in species and more in individuals, and had the highest diversity. In the restored grassland after light grazing, soil arthropods had the lowest evenness and diversity. In the restored grassland after moderate grazing, the individuals of soil arthropods were lesser but the major groups were more, and the evenness and diversity were higher. In the restored grassland after heavy grazing, the individuals of soil arthropods were more but the major groups were lesser, and the diversity was higher. Plant individuals’number, vegetation height and coverage, and soil alkalinity were the main factors affecting the soil arthropod community in naturally restored grasslands after different intensity grazing disturbance. It was implied that after 12-year exclosure of grassland, soil arthropod community could be recovered to some degree, while grazing disturbance had long-term negative effects on the arthropod community
