摘要
结合草地小流域特殊的地理位置及水土流失特点等实际情况,根据降雨、径流、产沙模数以及常用打草搂草机械幅宽等资料,初步对不同坡度条件下水平沟适宜间距进行优化设计,得出在20°、15°、10°、5°坡度时,水平沟适宜间距分别为19 m、25 m、31 m、55 m。
Combined geographical station of grassland small watershed with characteristics of soil and water conservation, according to rainfall, runoff, sediment production modulus and machine breadth and so on, the authors carried on the optimized design initially about the suitable spacing of level trench, and obtained when slope is 20°, 15°, 10°, 5°, the suitable spacing of level trend is 19 m, 25 m, 31 m, 55 m.
