摘　　要：土壤是动植物赖以生存的物质基础,是维系生态系统物质能量流通的重要环节。目前,在风蚀荒漠化地区生态环境重建过程中,土壤质量的修复问题已经得到广泛关注。多学科的交叉融合共同推动风蚀荒漠化地区土壤质量特征研究不断向前发展,并取得较大进展和丰硕成果。但是,总览国内外相关研究进展,其内容大都从土壤物理、化学和生物性质等方面进行梳理总结,而基于土壤质量特征影响因素的系统总结还不多见。因此,笔者基于风蚀荒漠化地区土壤质量特征变化基本过程的系统分析,从风力侵蚀、荒漠植物、荒漠动物和人类活动等4个方面构建和丰富风蚀荒漠化地区土壤质量特征研究体系,梳理总结了国内外相关研究进展,明确现有研究的不足,预测未来的研究发展方向。认为风蚀荒漠化地区土壤质量特征研究应在土壤质量变化的基本过程与机制、土壤质量与荒漠生态系统物质能量循环的耦合关系两个领域进行深入的拓展研究。Soil is the material basis for the living animals and plants, and also an important link to holdtogetherthe ener- gy and material circulation of the ecosystem. At present, the restoration of soil quality has been paid close attention in the process of ecological environment reconstruction in wind-induced desertified regions. The ever-growing body of research on soil quality characteristics in desertified regions indicates that great success has been achieved in this field. However, these studies are always summarized from the perspective of soil physical, chemical and biological properties, and lack a comprehensive consideration, or a systematic design, from the perspective of causative factors. Therefore, in this paper, we conduct a systematic analysis of the basic process changes in soil quality characteristics in desertified re- gions. We summarize the studies of soil quality characteristics in desertified regions both at home and abroad in the fol- lowing four categories ： wind erosion, desert vegetation, desert animals, and anthropogenic activities.Besides, we sum- marize the related research progress at home and abroad, make clear the shortcomings of existing research, and explore the future direction of development. Both basic process and mechanism of soil quality and coupling relationship between matter and energy cycle in desert ecosystem in soil quality need deep expansion research.
