摘  要：
以传统顺垄耕作为对照,研究了东北黑土区坡耕地治理过程中的水土保持效应。结果表明:坡耕地不同治理措施的保水效应和保土效应以水平梯田最佳,效应值分别为70.64%和77.61%,大小顺序为水平梯田>地埂植物地>横垄>对照,保土效应要优于保水效应,对照和横垄的土壤侵蚀程度表现为轻度,地埂植物带和水平梯田表现为微度;容重、蓄水容量、有效蓄容和稳定入渗率表征坡耕地治理措施土壤水源涵养效应指标的大小顺序为地埂植物带>水平梯田>横垄>对照。

摘  要：
In comparison with traditional the ridge along slope,benefit of soil and water conservation in the process of harnessing a sloping farmland in the Black Soil region of Northeast China was carried out.The results indicate that benefity of soil and water conservation was the best in the level terrace of different measures,and the value were 70.64% and 77.61%.We can put the following items as such orders:level terrace>buffer strip>contour cultivation>the ridge along slope,and effects on soil conservation was better than water conservation,the degree of soil erosion on contour cultivation and the ridge along slope were mild,level terrace and buffer strip were weak.Soil bulk density,soil water storage effective capacity,and steady infiltration rate were indicators of the size of water conservation functions of soil,we can put the following items as such orders:buffer strip>level terrace>contour cultivation>the ridge along slope.
