| 摘 要： | 水平梯田是控制坡耕地水土流失和实现旱作区农业高产与稳产的根本措施之一。通过研究发现，在黄土残塬沟壑区的泥河沟流域，梯田具有比较明显的蓄水、保水作用。距田埂愈近，越靠近外部，越接近土壤表层，土壤湿度越小，土壤愈干旱，越近里面，且越向下，土壤湿度越大。

| Abstract: | The level terrace is a basic measure of controlling the sloping farmland soil erosion, realizing the high and steady produce in drought area.The experiment results showed that level terrace has an obvious conservating water function in Nihegou watershed, breadth type terrace is better than narrow.On the breadth type terrace planting the corn is suitable.Some techniques should be taken to prevent or reduce evaporation of the ground humidity in 5～7 months in the narrow type terrace. |
