我省大部分坡岗地经常发生洪涝灾害,影响作物产量和机械作业,造成水土流失。由于没有工程或防护工程不到位,往往一场大雨形成坡水下山,将坡岗地能冲出2～3m深的大深沟,造成严重环境破坏。为此,如何使坡水安全下山,是坡岗地综合治理和水土保持的技术要点与难点。在坡岗地上,采取了一种“二沟二堤夹一槽” 的工程模式(如图)。实践证明
Floods and disasters often occur in most hillsides in our province, affecting crop yields and mechanical operations, resulting in water and soil loss. Because there is no engineering or protective engineering is not in place, it is often a heavy rain downhill, the slope can rush out 2 ~ 3m deep deep trench, causing serious environmental damage. Therefore, how to make the slope water safely go down is the technical point and difficulty of the comprehensive management of slope hillsides and soil and water conservation. In the slope on the ground, adopted a “two ditch two dike folder a slot” mode of engineering (pictured). Practice proved
