Reverse slope terrace
The invention discloses a reverse slope terrace, and relates to the technical field of irrigation and water conservancy engineering. The reverse slope terrace comprises a plurality of terrace structures which are sequentially arranged in the direction perpendicular to a contour line; each terrace structure comprises a terrace surface, ridges and a terrace ditch; the ridges and the terrace ditches are arranged at intervals in the contour line direction; the ridges and the terrace ditches are located on the two opposite sides of the terrace surfaces respectively; the ridges are used for planting slope protection plants; the terrace surfaces are used for planting crops; first included angles are preset between the terrace surfaces and the horizontal plane; the sides, close to the ridges, of the terrace surfaces are higher than the sides, close to the terrace ditches, of the terrace surfaces; each terrace structure further comprises a plurality of soil retainers arranged perpendicular to the the contour line direction in intervals; and the terrace surfaces, the ridges, the terrace ditches and the two adjacent soil retainers are jointly enclosed to form a retaining unit for retaining water flow. The reverse slope terrace can solve the problem that in the prior art, when the reverse slope terraces are built in hilly and mountainous areas, soil and nutrients are prone to losing.
一种反坡梯田，涉及农田水利工程技术领域，包括多级梯田结构，多级梯田结构沿垂直于等高线方向依次设置，梯田结构包括田面、田埂和田沟，田埂和田沟沿等高线方向间隔设置，且田埂和田沟分别位于田面的相对两侧，田埂用于种植护坡植物，田面用于种植农作物，田面与水平面之间预设有第一夹角，且田面靠近田埂的一侧高于田面靠近田沟的一侧，梯田结构还包括多个土挡，多个土挡沿垂直于等高线方向间隔设置，田面、田埂、田沟和相邻两个土挡之间共同围合形成用于拦蓄水流的拦蓄单元。该反坡梯田能够解决现有技术中丘陵山区在修建反坡梯田时存在的土壤与养分容易流失的问题。
