摘要
分析了产流模型研究和应用现状及平原河网区产、汇流特点，提出了遥感、ＧＩＳ支持下的平原河网区暴雨产流模型。模型将下垫面因素和暴雨因素列为随时空变化而变化的因子，并用遥感技术实时获取雨前土壤含水量等可变的区域下垫面数据；从物理成因出发，建立了反映暴雨产流内在机理、适合实际应用的数学模型，使模型具有高度的适应性，并对全区各时空单元的产、汇流情况分别进行计算模拟，模型计算结果与实际情况较为相符。
This paper analyses the present situation of the study and appliance of rainfall runoff yield model.Anew rainfall runoff yield model supported by GIS and remote sensing applied in river network areas of plain is putforward.The model considers the elements of underlying surface and storm as the factors yaring with changes ofspace and time,and uses remote sensing technique to timely acquire the variable underlying surface factors,such asantecedent soil moisture content.In addition to that,proceeding from the ...
