摘 要: 耕作侵蚀在我国耕地上普遍存在,其发生是不可避免的。作为土壤侵蚀的一种重要类型,它不仅加速了土壤侵蚀与土地退化过程、降低了农业生产力,还促使其它侵蚀方式的发生与发展。因此,耕作侵蚀的危害及潜在危险性应该引起足够的重视。本文在分析了耕作侵蚀的特点及其与水力侵蚀的关系以及概述了我国耕作侵蚀的现状之后,为减少耕作侵蚀,从发展持续农业的角度出发提出了采取多样化的耕作制度、合理的耕作方式、调整和改造现有的农业生态系统结构、耕作措施和农业生产管理措施等。
关 键 词: 水土保持;耕作侵蚀;持续农业;保护性耕作;可持续发展

Abstract: Tillage erosion occurs widely and is inevitable. Its hazards are obvious and should be adequately regarded. Tillage erosion does not only accelerate soil erosion and land retirement itself, and block sustainable agriculture development, but also speeds up development of other types of soil erosion. Based on analyzing the characteristics of tillage erosion and the relationship between it and water erosion and summarizing the status of tillage erosion in China. To reduce tillage erosion, some measures were advanced from the point of view of sustainable agriculture. They include taking diversified tillage system, rational tillage methods, adjusting and rebuilding structure of existing agro-ecosystem, tillage methods and agricultural management practices.
Key words: soil and water conservation; tillage erosion; sustainable agriculture; conservation tillage; sustainable development
