摘要
根据土壤水分平衡方程，利用甘肃省西峰逐日气象资料、牧草生长发育资料和土壤水分观测资料，对水分平衡中的入渗分量进行适当修正，建立了牧草地土壤水分动态模拟模型，获得一些有意义的参数值，根据预报试验表明，只要正确估计模型中的参数，该模型可以结合对未来气象要素的预报用于预测牧草地土壤水分动态，为旱地草场水分管理提供必要的手段。
In this paper, a dynamic simulation model of soil water for herbage was developed which was based on an equation fo water balance with improvment in infiltration component.Through observatios of daily weather, herbagegrowth and development and decade soil water in Xifeng, Gansu Province, some values of important parameters were obtained. Prediction experiment showed that this model, combined with weather forecast, can be used in predicting herbage soil water and provide an necessary method for grassland in arid regions if the parameters aer precisely estimated.
