摘要
针对淮北平原产汇流特点,提出了考虑大孔隙下渗、潜水蒸发、地下水和地表水之间转化的淮北平原概念性流域水文模型。模型将包气带概化为上、下两层,用蓄满产流原理分别模拟上、下土层的产流,用变动渗漏面积模拟大孔隙下渗,用地下水蓄水容量参数考虑地下水对地表水的反馈。日径流模拟应用实例表明,提出的淮北平原水文模型具有一定的精度,可以用于淮北平原"四水"转化关系研究、水资源评价等方面。
A new conceptual hydrological model of Huaibei Plains is proposed for the runoff and convergence characteristics in Huaibei Plains,considering macro-pore infiltration,phreatic evaporation,transformation between the groundwater and the surface water.In the model,the vadose zone is divided into two layers,the upper layer and the lower layer by using the theory of stored-full runoff to simulate the runoff by changing leakage area to simulate macro-pore infiltration and using the parameter of groundwater storage capacity to reflect the relation of groundwater and surface water.The example of the daily runoff simulation shows that the model has a certain accuracy and could be used to the research on transfer relations of the four-state water and water resources evaluation.
