| 模型所需参数较少，扩充方便，结构透明，三种极端条件测试和六种参数的敏感性测试以及与Hydrus-1模型的比较表明模型假定合理，没有发生结构性错误。对灌区两季冬小麦生育期的土壤水分转化模拟结果表明降雨和灌溉是主要供水水源，毛管水上升量很小，底部渗漏较大，而土壤储水量变化很小。当将尺度由作物根系层扩展到整个饱和非饱和带时，地下水的回归利用使得底部渗漏占总供水量比例由27.59%减少到16.15%。 |

The model needs less Paramater, expands conveniently and the structure is transparent.in comprison with Hydrus-1 model,the test of the three kinds of extreme conditions and the sensitivity of the six parameters indicates that the model assumption is reasonable and there is no Structural error.the simulation of soil moistrue conversion with Growth period of two season's irrigated winter wheat indicates that the main supply of water is the natural rain and the irrigation. the increased volume of Capillary water is less and the leakage at the bottom is too large, while there is little change in water storage of the soil.When the scale from the crop root zone extends to the saturated and unsaturated zone, the regression utilization of under-ground water causes the bottom of the total water supply increased from 27.59% to 16.15% reduction. 希望楼主能信守承诺！ |
