拦泥淤地坝是黄土高原水土保持的一项重要工程措施,多年的实践证明,其拦泥、减洪、增产效益十分显著。广大群众对打坝淤地有极大地积极性,也积累了丰富的经验。为加速黄土高原建设,根据国家计委和全国水土保持工作协调小组的指示精神,在黄河中游水土流失严重地区,要以小流域为单元,在坡面治理的基础上,修建治沟骨干工程。 总结各地经验,小流域骨干淤地坝的建坝顺序总的来看,以“自下而上”为优。主要
Dams dam silt dam is an important engineering measure of soil and water conservation in the Loess Plateau. Years of practice have proved that it is very significant in reducing sludge, reducing floods and increasing yield. The vast majority of the people have great enthusiasm in fighting dams and also have accumulated rich experience. In order to accelerate the construction of the Loess Plateau, according to the instructions of the State Planning Commission and the National Coordination Group for Soil and Water Conservation, in the area of serious soil erosion in the middle reaches of the Yellow River, based on the small watershed, based on the slope control, construct the backbone irrigation project. Summarizing the experiences of all localities, the sequence of the construction of the key silty dam in the small watershed is generally based on the principle of “bottom-up”. main
