淤地坝是防止黄土高原水土流失、实现该区经济可持续发展以及减少入黄泥沙的重要措施。而黄土高原在淤地坝建设中已获得了巨大成绩。但在建坝过程中仍有不少教训需要总结,除了工程建设缓慢、标准低和现有工程老化失修等存在问题外,还必须注意以下问题:(1)地质地貌条件是建坝的基础,要根据其条件布设;(2)根据沟谷系统发育的地貌实体及演变规律,构建完整的淤地坝体系;(3)必须了解淤地坝所在地区的地貌发育阶段;(4)区分建坝区的自然侵蚀和加速侵蚀。
Warping dam is to prevent soil erosion in the Loess Plateau, to achieve sustainable economic development in the area and reduce the Yellow River sediment into important measures. The Loess Plateau in the construction of silt dam has made great achievements. However, there are still many lessons to be learned in the process of dam construction. In addition to the problems of slow construction, low standards and aging and disrepair of existing projects, the following problems must be paid attention to: (1) Geological and geomorphic conditions are the foundation of dam construction, (3) It is necessary to understand the stage of geomorphologic development in the area where the warping dam is located; (4) To distinguish the dam area from the dam area Natural erosion and accelerated erosion.
