摘要	针对如何合理配置水窖以解决黄土高原梯田种植苹果存在的水资源短缺问题,利用WEPP模型,在对0～200 cm土壤储水量动态变化模拟验证的基础上,以满足梯田苹果在不同典型代表年的生育期需水为目标,对水窖进行优化配置。结果表明:在更新土壤及作物管理数据库后,WEPP模型可实现对梯田苹果园0～200 cm土壤储水量的动态模拟;利用土壤水分动态变化选择典型年来进行水窖优化配置,更能满足苹果的需水要求;黄土丘陵沟壑区适宜的水窖配置干旱年为1 150 m3/hm2,平水年为180 m3/hm2,湿润年为50 m3/hm2。该研究为高效利用该区有限水资源提供了一种基于土壤水分动态变化来满足苹果生长需水的水窖优化配置方法。
其他摘要	Aiming to solving the problem of water resource shortage in apple orchard on terrace by reasonable allocation of water cellar，water cellars were optimally allocated based on the verification for water storage dynamic change in 0 － 200 cm soil using WEPP model，to meet the water demand of Malus pumila Mill during its growth period in different typical years ． The results showed that water storage in 0 － 200 cm soil could be well dynamically and simultaneously simulated when the databases of soil and crop management in WEPP model were updated; The water cellar should be optimally allocated base on soil water dynamic variation in typical year，which could better meet the water demand of the Malus pumila Mill; The allocation of water cellar is 1 150 m3 /hm2 in typical dry years，180 m3 /hm2 in the normal years and 50 m3 /hm2 in the wet years in loess hilly and gully region． This study provided a good water cellar optimal allocation method，base on soil water dynamic variation to meet the water demand of the Malus pumila Mill，for efficient utilization of the limited water resources．
