摘　　要：根据灌区水循环的一般特征及河套灌区独特特征,建立了包括地表水、土壤水和地下水模型的河套灌区水循环数学模型,并在模型求解过程中实现三者的简单耦合。分别计算了灌区生育期和秋浇期的净灌溉水量、土壤含水量变化及渗漏情况,地下水变化情况等。模拟结果显示,河套灌区水循环过程为一种"负水平衡"的垂向水循环。The hydrologic cycle is significant to the sustainable development of the irrigation area. A system comprised of surface runoff model, soil water model and groundwater model was built up, according to the characteristics of hydrology in Hetao irrigation area, in Inner Mongolia. With the aids of this system, the net irrigation demands, variation of soil water content, infiltration and the change of the groundwater during different irrigation period were worked out. The results indicate the hydrologic cycle in Hetao irrigation area was a negative balance present in vertical direction.
