坝地是黄土高原地区的主要产粮基地之一。该区农作物生长期暴雨频繁，坝地易受洪涝灾害侵扰，保收中较低。通过对影响晋西地区坝地防洪保收有关因素的观测、分析和玉米、高粱耐淹试验及群众大量防洪保收经验的调查研究，提出了坝地农作物高度、洪水频率、现地面积与其所控制的区间渠流面积之比值、土壤入渗、不同条件下坝地防洪保收与涵洞泄量计算模型等坝地防洪保收影响因素的量化指标和现地玉米、高粱最大允许淹水深度与淹水历时以及排洪渠开挖等一整套确保坝地在有效拦犯前提下的防洪保收技术要点，对提高黄土高原同类地区坝地保收率，充分发挥淤地坝坝系工程的泄洪、拦泥、增产作用具有一定的指导和实用意义。
Dam is one of the main grain-producing bases in the Loess Plateau. The heavy rain in crop growing season in this area is frequent, and the dam area is easily invaded by floods and floods, with a lower guarantee. Based on the investigation and analysis of the related factors affecting the flood control and collection of dam sites in Shanxi Province and the investigation of flood-resistant maize and sorghum flood-proof experiences and flood control and collection experience of the masses, the author puts forward some suggestions on cropland height, flood frequency, The ratio of controlled canal flow area, soil infiltration, under different conditions of flood control and storage of culverts and the calculation model of flood discharge dam flood control factors such as the impact of quantitative factors and the current maximum allowable flooding depth of corn and sorghum and Flooding duration and excavation of drainage channels to ensure a comprehensive dam under the premise of effective flood control technology to improve the same area of ?? the Loess Plateau to protect the rate of dam area, give full play to dam dam system of flood discharge, Mud, increase production has some guidance and practical significance.
