摘  要:
控制排水技术是调控农田水资源的主要措施。该文采用原型观测与模拟模型相结合的研究方法,在平原区农田排水大沟设置控制设施的大型观测试区,研究其对地下水的调控效果;利用三维地下水流运动模拟模型,进行了不同控制条件下田间地下水的动态模拟,获得不同控制方案的优化结果。研究结果表明:排水大沟加设控制设施可有效避免地下水资源的流失,有利于作物对地下水的利用。该研究对农田水资源的调控和控制排水工程建设有参考价值。

摘  要:
Controlled drainage technology is a main measure for regulation and control of field water regime. Combined prototype observation with simulation model, based on a large prototype observation of drainage control through construction of a damming structure on main drainage ditch, the effect of controlled drainage on the regulation and control of groundwater table was studied. By means of a three-dimensional dynamic groundwater model, field water table elevations under the different controlling conditions were simulated and optimal results were put forward. The results indicate that the controlled drainage technology can avoid availably excess loss of groundwater resources, and is propitious to use groundwater for crops. The research results supply reference for the regulation and control of farmland water resources and the drainage control structure construction.
