降雨过程中，随着产流时间的延长，坡地产沙量呈加速增加的趋势，而且增加速度显著快于坡面径流。
In addition, with the extension of runoff-yielding time during the rainfall process, the sediment from slope tended to accelerate more rapidly than runoff volume increase.
坡地修成梯田后，因种植田面由坡变平和地埂占地，使种植面积减少；
When slopeland is improved into terraced field, the plantable area is reduced because of the surface of farmland becoming flat and the land used for constructing earth banks.
坡面水流使坡地土壤厚薄不均，或形成异源剖面，并可使埋藏土壤因冲刷而出露。
Water flow on slope makes the soil depth uneven at different places, forms the polygenetic soil profiles, and exposes the buried soils by erosion.
“坡坝地”工程用治沟的形式治坡：一架山一面坡从上而下坡地和梯田水平带状相间排列至沟沿线。
The engineering of dam on slope land is one of the gully control measures to manage the slope land. From the top to the bottom edge on slope land, it is terraced land alternating with slope land.
