摘　　要：本文基于SWAT(Soil and Water Assessment Tool)构建海河流域分布式水文模型。针对海河流域的特点,对平原区河网和入海口进行合理概化,对土壤类型和土地利用方式进行重分类处理。应用1995～2002年水文气象系列资料和下垫面空间分布信息,对模型的参数进行优化和灵敏度分析,最后选取多个站点对模拟结果进行检验与分析。研究成果为SWAT模型在国内复杂大流域的应用提供了范例,也为海河流域变化环境下的水资源与水环境综合管理提供重要的水文学基础支撑。At present, there isn＇t a flexible and actually running distributed hydrological model in the Hal river basin. Based on SWAT （Soil and Water Assessment Tool）, a whole basin distributed hydrological model for Hai River basin is presented. In this model, according to the Hai river basin characteristics, the river networks in the plain region is reasonably modified, the 17 river mouths are generalized, the 28 big reservoirs are considered. Because of the difference between China and USA, the soil type database and land use types are transformed and reclassified. By using the hydro meteorological data from 1995 to 2002, we carry on the optimization and sensitivity analysis of the model parameters based on the parameters analysis system building by ourselves. The simulation results are reasonable and can provide the important hydrology supporting foundation for the water resources management and the eco-environment＇s restoration in the Hal river basin.
