Abstract: The water resources in the southern mountainous area of Naiman Banner, Inner Mongolia, are very scarce and unevenly distributed in time and space. Although its topography is complex, it occupies most of the cultivated land in the whole Banner. The monsoon and drought climate has intensified, causing the local agriculture to “rely on the weather for food for nine years”. The local water conservancy workers and the masses of the people have used many water resources development and utilization technologies in their years of practice and exploration. Through the elaboration and analysis of four classic technologies, such as small (2) type reservoirs and pond projects, subsurface flow interception projects, radial large-mouth wells, and mobile pumping stations, the paper demonstrates their economic and social benefits, which can effectively solve the practical difficulties of local agricultural water shortage, Alleviating and reversing the adverse situation of “nine droughts in ten years, relying on the weather” is an agricultural drought relief measure with strong vitality, which has a strong recommendation significance for agricultural irrigation in other similar regions in China, and is worthy of serious summary and continuous promotion and application.

摘要： 奈曼旗南部山区水资源十分匮乏且时空分布不均,其地形地貌复杂却占据着全旗大部分耕地,季风性、干旱性气候又加剧造成了当地农业“十年九旱、靠天吃饭”。当地水利工作者和广大群众在经年累月的实践摸索中运用了许多水资源开发利用技术,文中通过对小(2)型水库与塘坝工程、截潜流工程、辐射大口井、移动式扬水站等4种经典技术应用的阐述分析,论证了其经济效益与社会效益,能够有效解决当地农业用水紧张的实际困难,缓解扭转“十年九旱、靠天吃饭”的不利局面,是具有强大生命力的农业抗旱措施,这对我国其他类似地区农业灌溉具有很强的引荐意义,值得认真总结,不断推广应用。
