摘要：

保护性耕作是一种有利于保护土壤、水等自然资源的生产潜力，提高土地生产力并防止土壤和水资源退化的一种土地利用方式。在中国耕地面积逐年减少，土壤肥力持续下降，水土流失严重的情况下发展保护性耕作具有重要意义。从土壤物理性状、土壤肥力状况、土壤生物学特性、土壤水分和温度几个方面分析了保护性耕作对土壤综合特性的影响，阐述了保护性耕作对减轻土壤水蚀、风蚀的作用，总结了目前中国保护性耕作研究与应用现状及发展前景。

Abstract:

Conservation tillage is benefit for us to protect soil and water resources, conserve and increase their production potential and prevent degradation. It is significant in China due to the declining of cultivated land, the decreasing of soil fertility, and the expanding of soil erosion. Effects of conservation tillage on soil physical and biological property, fertility, moisture and temperature are analyzed. The roles of conservation tillage on water erosion and wind erosion control are also expressed. Study and application status and prospects of conservation tillage in China are summarized at last.
