摘要
以贵州省三岔河流域为研究区,构建了一个以表层岩溶带产流过程为核心的岩溶流域概念性分布式水文模型。模型充分考虑了岩溶地区下垫面条件的复杂性,根据含水介质的不同,将岩溶水分为不同径流成分并分别汇流演算。模型中的大部分参数通过野外实验直接获得,通过对研究区1991―2012年共22 a逐日过程进行模拟演算,结果表明：该模型在三岔河流域有良好的适用性,径流深及洪峰误差均控制较好。
With the increasing demand for water, the importance of karst aquifers as a resource has grown.Modeling the response of karst aquifers and water storage in such systems thus becomes an important challenge.Considered the complexity of the underlying surface at the karst area in Southwest China, a conceptual distribution hydrologic model which could simulate the main physical processes of hydrological cycle especially the runoff generation in the epikarst zone is proposed. The model structure is simple and most parameters can be obtained from field work directly. The model is calibrated and applied to the Sanchahe Basin which is located in Guizhou Province in the Southwest of China. The simulation results are satisfactory.
