中文摘要有限顺坡耕作坡耕地地块坡长因坡度而异,可依据细沟侵蚀发生临界确定,在野外调查和实验基础上提出了有限顺坡耕作地块坡长推荐值。研究表明,较无措施坡耕地而言,采取水平沟、埂坎和地埂植物篱等措施的坡耕地减蚀效益分别达到63%、77%和94%,具有显著的理水保土作用。同时,有限顺坡耕作模式具有成本低,高效实用,操作简单方便,农民易于接受等优点,适合在三峡库区推广。
英文摘要The slopelength of each field varied with slope gradient and could be decided by the critical rill erosion slopelength. Slopelengths for different slope gradients on the basis of field surveys and experiments were recommends. The results indicated that compared to the bare slope farmland, the erosion reductions by horizontal ditches, terrace ridge and bank, terrace hedgerows were 63 %, 77%and 94  %, respectively, showing significant soil conservation effects. In addition, the limited downslope tillage was characterized by low cost, efficient, practical and simple operation, farmers readily acceptable, and it was suitable for promotion in the Three Gorges reservoir area.
