| 摘 要： | 土壤风蚀是土壤颗粒在风力作用下的剥蚀、搬运和沉积的过程。风蚀使土壤中的大量营养物质损失，导致土地生产力下降，促使地表养分的再分配，促进碳（C）循环。土壤颗粒团聚体稳定状况、不同土地利用方式和人类活动都会影响土壤风蚀度的大小，从而进一步影响土壤中养分的分布及C在土壤圈、大气圈和生物圈中的循环。针对过去对土壤风蚀引起的土壤养分及碳循环研究的不足，提出今后的研究工作应当注重：（1）土壤风蚀环境效应；(2) 土壤的潜在风蚀微观机理；（3）风蚀物在土壤-植物-大气系统间的互馈机制研究。

| Abstract: | Wind erosion is a progress that soil particles are disrupted, transported and deposited by wind, which causes much nutrient material's lose as well as soil nutrient and land productivity's decline. It also promotes the redistribution of surface soil nutrient and carbon cycling in dry lands. The erodibility of soil by wind is dependent on the state and stability of the soil aggregate, different land use types and human's activities, which farther influences the nutrient and carbon cycling and redistribution among soil, atmosphere and bio-sphere. Based on deficiency of research on wind erosion induced soil nutrient and carbon cycling in the past , we summarize the research progress and analyze the existing problem of wind erosion; furthermore, we point out that the key research work that must be done in future should be focused on:(1) the environmental problem which causes by wind erosion, (2) soil's potential wind erosion micromechanism research, and (3) wind erosion induced fine particle feedback mechanism among the soil-vegetation-atmosphere system. |
