【摘要】 本文用河北雄县试验站的实测资料验证了一维土壤水动力学模型—WAVE模型 (WaterandAgrochemicalsintheSoilandVadoseEnvironment) ,率定了土壤水力学特性参数和作物根系吸水函数 .在此基础上 ,应用该模型模拟不同地下水埋深和不同作物腾发量条件下根区底部向上水分通量的变化 ,从而得到地下水对根层的补给量与根层土壤储水量的关系 .把这一关系用于制定和评价灌溉制度的水量平衡模型当中 ,提高了模型的适用范围和模拟精度更多还原

【Abstract】 A 1\|D soil water dynamic model\|WAVE (Vanclooster et al 1994) is calibrated and validated by comparing the simulation results with the field experiment data.The model is used to simulate the upward flux at the bottom boundary of root zone in different conditions of groundwater depth and potential crop evapotranspiration.A semi\|empirical relation between the capillary rise to the root zone and the water stored in the root zone is derived.This relation is used to improve the soil water balance model to better consider the groundwater contribution to be applied in the irrigation scheduling studies.更多还原
