摘要
以陕北延安黄土高原为例 ,经分析得出 :(1)黄土高原在实施竹节水平沟整地工程时 ,设计暴雨可采用 10年一遇 3h降水 6 0 mm的标准 ;(2 )每个竹节的蓄水容积不得小于 2 .5m×1.2 m× 0 .
Based on the analysis of rainfall data of Yanan city in loess plateau,the techniques for building a kind of contour trench which is alike bamboo section of trench had been put forward.Taking Yanan in the Loess Plateau as an example,the design standard of the bamboo contour trench is the rainfall intensity of 60mm/3h under rainfall frequency of once during 10 years. The volume of water harvested in a contour trench is about 2.5m×1.2m×0.35m.
