我们进行了一系列风洞实验来阐明有成行排列根的沙地表面砂化过程的特征及其对侵蚀率的影响。实验在一个横截面为 50ｃｍ× 4 0ｃｍ ,长 1 7ｍ的室内风洞 (顺翼展方向的 )进行。准备了 6种砂样品 ,并放置在 6 0ｃｍ× 30ｃｍ的砂盘上。每种样品由细砂 (ｄ 0 .84ｍｍ)和粗砂 (
We conducted a series of wind tunnel experiments to elucidate the characteristics of the surface sanding process with rows of roots and their effect on erosion rate. The experiment was conducted in an indoor wind tunnel (spanwise direction) with a cross-section of 50 cm × 40 cm and a length of 17 m. Six kinds of sand samples were prepared and placed on a sand tray of 60 cm x 30 cm. Each sample consisted of fine sand (d 0 .84 mm) and coarse sand
