摘　　要：平原区降雨、蒸散发、产流和潜水位起伏等水文循环过程之间的联系十分密切,研究其相互间转化规律具有十分重要的意义。基于已有的平原区降雨产流模型,通过考虑产流下渗、地下潜水蒸发及微地形的影响,分别计算了水面、水田、旱地和城镇建设用地四种下垫面的地表水和潜水的交换量,将交换量作为平原区潜水的源汇项构建了潜水模型,并以太湖流域平原区作为试验区,通过模拟潜水位验证了平原区降雨产流模型的合理性。Hydrological cycle processes in plain area,such as rainfall,evapotranspiration,runoff,phreatic water level fluctuations are closely linked with each other.And the research of the transformation law has important significance.Based on the original rainfall-runoff model,the exchange capacity between surface water and groundwater is calculated for four types of underlying surface： water surface,paddy fields,dry land surface and urban construction land and calculate by considering the impact of the infiltration,underground water evaporation and micro-topography.The exchange capacity is taken as the source-sink term of plain region to establish phreatic water model.Taking plain region in Taihu basin for test region,the rationality of plains rainfall-runoff model is verified by simulating water level of phreatic water.
