Abstract: Grain production in North China is prominent in the whole country, but there is a serious shortage of agricultural water. In this study, winter wheat in North China Plain was taken as the research object. Firstly, the experimental data of North China in 2004 and 2006 were used to analyze the water movement law and utilization efficiency under the traditional irrigation system. Combined with WHCNS model, different combination irrigation scenarios were simulated (the total irrigation amount was set to change from 100mm to 450mm, and the irrigation times were increased to 5 times), and the irrigation amount was optimized by using the comprehensive index method. Finally, 350mm is the best irrigation schedule in the simulation.

摘要： 华北地区的粮食生产在全国范围内地位突出,但是农业用水严重短缺;该研究以华北平原冬小麦为研究对象,首先利用华北地区2004年和2006年试验数据分析传统灌溉制度下水分运移规律及利用效率,结合WHCNS模型进行不同组合灌溉情景(研究设置总灌水量变化范围由100mm至450mm,提高灌水次数至5次)的模拟研究,使用综合指数法对灌溉量进行优选研究。最终得出350mm为设定组合情境中的最佳灌溉量。
