Benefits of Stone-sill Reverse-slope Terraces to Soil and Water Conservation on Thin-soiled Sloping Farmland in Earthy-Rocky Mountainous Area of North China
To address the issue of soil erosion on sloping farmland with thin soils in the earth-rocky mountainous area of north China,we established standard runoff plots to investigate the comprehensive soil and water conserva-tion effectiveness of stone-sill reverse-slope terraces.Our findings revealed a significant control effect on water and soil loss:runoff and sediment were reduced by 68.57％and 94.29％,respectively,compared to contour farming.Stone-sill reverse-slope terraces effectively increased soil moisture content and ensured a more uniform distribution of water across the slopes.The total soil moisture content increased by 7.78％compared to contour farming plots.Additionally,the stone-sill reverse-slope terraces markedly enhanced crop yields on sloping farmland;corn yields increased by 12.69％compared to contour farming.Our design and study of the stone-sill reverse-slope terrace con-tribute to the soil and water conservation methods for thin-soiled sloping farmland in north China's earth-rocky mountainous areas.
