摘要
“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。坡面产流,梯田蓄水。坡面植树种草,梯田种粮种菜,梯田外侧筑埂坝(边埂)挡水,坡、梯、坝三结合,内侧设旱井,涝蓄旱灌,变梯田为水地。,广泛适用于山区尤其是黄土丘陵沟壑区的农田建设,是山区水土保持综合治理、发展生态农业、农林牧副多种经营的好模式。
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. The terraced land stores runoff water from slope land. Trees and grass could be planted on the slope for soil erosion controlling. The dam shaped ridge is constructed on the outside edge of terraced land for water controlling and dry wells constructed on the inside edge for water storage. The terraced land can be irrigated using the stored water. This kind of engineering model could be widely used in mountainous areas, especially in the loess plateau region. It is an effective model for soil conservation and ecological agriculture development.
