摘要： 纵观土壤侵蚀研究的历史，风蚀和水蚀被认为是土壤侵蚀的主要形式。尽管近年来耕作侵蚀研究取得了巨大进展, 但迄今放牧侵蚀研究较少。本文探讨了放牧侵蚀研究的意义，回顾了国内外研究现状和存在的问题，提出放牧侵蚀是由于草原动物的直接作用而导致在过牧草地上土壤物质的重新分配。放牧侵蚀作为过度放牧的指示向量，是一个今后值得大力研究的领域，这不仅有益于草地载畜量评定、碳素减源增汇研究，而且在草地退化程度诊断和退化草地治理中具有重要指示意义。
Abstract: Historically, water and wind erosions were assumed to be the major forms of soil erosion. Though the studies of tillage-induced erosion have been developed greatly in recent years, few studies were made on grazing-induced erosion. This paper discussed the significance of the research on grazing-induced erosion, and reviewed the current status and existed problems of the research, based on both domestic and foreign researches. Grazing-induced erosion induces the redistribution of soil matters on overgrazing grassland as a direct result of animals. As a vector of overgrazing, grazing-induced erosion is a study area which deserves greater attention in the future. The research on grazing-induced erosion not only benefits the determination of livestock carrying capacity and the increase of soil carbon sequestration, but also has an indicative meaning on diagnosing the degradation degree of grassland and on managing degraded grassland.
