| 摘 要： | 为了探讨东北典型黑土区坡耕地的治理情况，综合现有研究成果分析了不同坡度下顺坡垄作改横坡垄作、水平梯田、等高植物篱等措施的蓄水保土效益。结果表明：它们在黑土区能够发挥较高的水土保持效益坡度适宜范围，从而确定在0～5°、5°-8°、8°～15°坡度级别的坡耕地上分别采用以改垄措施、等高植物篱措施、水平梯田措施为主的措施进行治理，在〉15°的坡耕地上选择退耕还林。

| Abstract: | Choosing the appropriate soil and water conservation measures has importance to control the losses of soil and water on sloping farmland in black soil region.In this paper,some control measures such as the contour ridge tillage,contour hedgerow intercropping,bench terrace have been studied,and it is found that they have different effects on soil and water conservation and play a high efficiency of soil and water conservation on sloping farmland with different gradient slope.So some kinds of control modes ca... |
