【摘要】 日径流过程模拟预报的准确程度对于合理利用水资源于农业灌溉、工业生产、生活用水以及水力发电等具有很重要的意义。日径流预报有很多方法,分布式水文模型是国内外水文界的热门研究课题,将基于GIS的分布式水文模型应用于灌区与水库联合调度系统中,应用李兰教授开发的LL-Ⅱ型分布式水文模型对东风渠灌区白河水库日径流过程进行模拟预报,取得了较好的效果。更多还原

【Abstract】 The accuracy of daily runoff process simulation and forecast is very important for the reasonable use of water resources in agricultural irrigation,industrial production,domestic water consumption and hydropower and so on.There are many methods for daily runoff process forecast,among which,the distributed hydrological model is a hot issue in the field of hydrology domestic and abroad.The distributed hydrological model based on GIS is applied in the joint operation of irrigation district and reservoir in this paper,the daily runoff process of Baihe Reservoir in the irrigation district of Dongfeng Irrigation Canal is simulated and forecasted by using the LL-Ⅱ distributed hydrological model developed by professor LI Lan and the result is good.更多还原
