【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。
[Abstract]:Soil is the material basis for the survival of animals and plants and an important link to maintain the flow of material and energy in the ecosystem. At present, the restoration of soil quality has been paid more and more attention in the process of eco-environment reconstruction in the area of wind erosion desertification. Multidisciplinary cross-fusion promotes the continuous development of soil quality characteristics in wind-eroded desertification areas and makes great progress and fruitful results. However, most of the related research progress at home and abroad are summarized from the aspects of soil physical, chemical and biological properties, but the systematic summary based on soil quality characteristics is still rare. Therefore, based on the systematic analysis of the basic process of the change of soil quality characteristics in the area of wind erosion and desertification, from wind erosion to desert plants, The research system of soil quality characteristics in the area of wind erosion desertification was constructed and enriched in four aspects such as desert animals and human activities. The related research progress at home and abroad was summarized, the deficiency of existing research was clarified, and the development direction of future research was predicted. It is suggested that the study on soil quality characteristics in wind-eroded desertification areas should be carried out in two fields: the basic process and mechanism of soil quality change and the coupling relationship between soil quality and the material and energy cycle of desert ecosystems.
