摘    要:农田土壤水分动态是作物需水管理的关键。运用水量平衡模型和HYDRUS-1D模型对农田土壤水运移动态进行研究。结果表明农田土壤水分随降水、蒸发变化具有明显的时空分异特性,调节了不同时期作物的需水要求。HYDRUS-1D模型等数值模拟方法的应用为深入揭示农田土壤水分运动规律,协调不同时期农田供水与作物需水之间的矛盾提供了可靠依据。图3,表2,参16。

关 键 词:土壤水分  水量动态平衡  数值模拟

Abstract:The dynamic of the agricultural soil water is the key issue to regulate the crop water requirement. In this paper, the water balance model and HYDRUS -1D model were used to study the process of the soil water dynamic.The result presented that soil water moisture has the spatial and temporal variability with the precipitation and evapotranspiration.The soil water regulated the crop water requirement in different growth period.Numerical model had become the important tools to study the water dynamic, its will give us scientific guidance to regulate the agricultural water supply and crop water requirement.
Keywords:soil water  dynamic of water balance  numerical simulation
