摘　　要：合理的排水系统对提高作物产量、预防涝渍灾害有一定的作用。运用DrainMod模型模拟渠南灌区作物产量受降雨量和排水沟布置的影响。根据分析结果可以初步推断,水稻产量对干旱因子和排水沟布置影响较敏感,小麦产量对涝渍因子和排水沟间距影响较敏感。The reasonable drainage system have a positive effect for promoting crop growth and preventing waterlogging disasters.DrainMod model based of field drainage was run for crop yield of rainfall and different drainage systems in Qu-nan irrigation area.The results show that drought and water shortage are the main factors affecting rice yield,and waterlogging is the main factor affecting wheat yield;rice yield is significantly affected by drainage distance and depth,and wheat yield is greatly affected by drainage distance.

关 键 词：DrainMod模型 渠南灌区 降雨量 排水间距 排水深度 作物产量
