山体滑坡后形成裸露坡面,虽然坡面产生的泥沙量较少,但如果这种裸坡面积很大,或面积虽小而相对密集,又不能被植物自然覆盖,从而产生的泥沙就会缩短下游堤坝的寿命,甚至造成灾难性后果。因而研究裸坡泥沙量的产生及移动机理有助于确定山间径流中泥沙运动以及裸露山坡重新恢复植被所需要的条件。1 试验处理试验地点设在靠近凯苏河一级支 The formation of bare slopes after landslides, although less sediment generated by the slope, but if this bare slope area is large, or small but relatively dense area, they can not be covered by the natural plant, resulting in sediment on the Will shorten the life of downstream dams, and even have catastrophic consequences. Therefore, the study of the production and movement mechanism of sediment in bare slope can help to determine the conditions required for sediment movement in mountain runoff and the restoration of vegetation on bare slopes. 1 Test Treatment The test site is located near the first branch of the Kai Su River
