摘要:: 应用江西典型红壤坡地梯田与坡耕地小区的观测资料，对坡改梯的水土保持效应进行了分析研究。结果表明：坡耕地改梯田后蓄水保土效益显著提高，蓄水效益高达67.6%，保土效益达85.0%以上；梯壁植草能大大提高梯田的蓄水保土效益，采取前埂后沟+梯壁植草方式的水平梯田与梯壁不植草的对照水平梯田比较，其蓄水效益达59.7%，保土效益达98.2%，适宜在南方红壤坡地广泛推广。

Abstract:: With observation data of terrace and slope land runoff plots, the authors analyzed the soil and water conservation benefit of terracing.The results showed that the soil and water conservation benefit of terracing was remarkbly lifted, the benefit of reducing runoff loss was 67.6%, and reducing soil loss was over 85.0%.Planting grass on terrace wall could improve enormously the soil and water conservation benefit.Compared with the terrace with no grass on its wall, the terrace with sod grass on its wall, mound before its platform and ditch behind its platform, was the most effective method to conserve water and soil.Its benefit of reducing runoff loss by 59.7%, and reducing soil loss by 98.2%.This terrace should be widely spread on red-soil slope land in southern China.
