| 摘 要： | 在田间试验验证的基础上,利用SWAT2000模型对黄河下游引黄灌区冬小麦、夏玉米在不同灌溉条件下产量、耗水量以及水分利用效率等的时空变化进行了模拟,结果表明,冬小麦缺水情况比较严重,夏玉米生育期降水量基本能满足其耗水量的需求.灌溉对提高作物产量以及耗水量有很大的影响,然而随着灌水量的增加,作物产量以及耗水量增加的幅度并...

| Abstract: | SWAT2000 was calibrated and validated based on the field experiments and was used to simulate the temporal and spatial variation of grain yield,actual ET and water use efficiency(WUE) of winter wheat and summer maize under full irrigation,scheduled irrigation,and no irrigation in the irrigation districts along the lower reaches of the Yellow River.From the simulated results,it can be seen that winter wheat was seriously lack of water and precipitation during summer maize can almost satisfy the actual ET nee... |
