在北方干旱、半干旱地区,水力侵蚀导致沟壑发育,土地支离破碎,资源性缺水与工程性缺水常常为水土保持综合防治的实施带来困扰,治水保水就显得尤为重要。开发灌溉水源、发展小型蓄排引工程,积极加强雨洪集蓄利用成为首要选择。以宁夏回族自治区几个小流域为例,对水窖、涝池、滚水坝等小型蓄引工程设计进行研究探讨。
In the arid and semi-arid areas in northern China, water erosion leads to the development of gullys, fragmentation of land, resource-based water shortages and project-induced water shortages, which often cause problems for the implementation of integrated water and soil conservation. Water and soil conservation is especially important. Development of irrigation water sources, the development of small-scale storage and drainage projects, and actively enhance the accumulation and utilization of rainwater as the first choice. Taking several small watersheds in Ningxia Hui Autonomous Region as an example, this paper studies the design of small-scale storage engineering such as water cellar, waterlogging pool and rolling dam.
