摘要
结合野外调查和文献报道,对三峡库区坡改梯、坡面水系工程、保土耕作、种植模式优化、植物篱建设、退耕还林等坡耕地水土保持措施的特点、设计、类型、减蚀效益进行了综述。从水土保持措施的适宜条件、措施的优缺点、农民采纳意愿等方面分析了不同措施的适宜性。在此基础上,对三峡库区坡耕地这一特殊地域单元水土保持传统措施理论、组合措施、措施适宜性、原位观测等方面的研究进行了展望。
The features, types, design and sediment-reduce benefits of current soil conservation practices in terracing slopeland, equipping sloping surface water system, conservation tillage, optimizing planting pattern, building hedgerows, de-farming and restoring forest are summaricd. Furthermore, conservation practice suitability in terms of setting conditions, merits and fauhs, farmers＇ adoption willingness are compared. In addition, traditional farming system, conservation combination, conservation practice suitability and onsitc observation are recommended towards this particular geographical unit.
