摘要
基于SWAT(Soil and Water Assessment Tool)来构建房山区水资源分布式水文模型,对模型的几个重要参数进行率定,应用2002-2005年的水文气象数据进行ET(evaportranspiration)模拟,将模拟结果与遥感ET数据进行对比分析.结果显示模拟相对误差在10%以内,能够为水资源管理提供重要参考.
Based on SWAT model, the water resource distributed hydrological model for Fangshan District of Beijing is constructed and several important parameters of the model are calibrated in this paper. Using the hydrological and weather data from 2002 to 2005, the ET (evaportrhanspiration) simulation is carried out and the result is compared with the remote sensing data of ET. It shows that the relative error of simulation result is low in 10% and can supply important reference for the water resource management.
