摘　　要：针对白洋淀流域水资源保护工作开发了分布式水文模型WEP-L模型。WEP-L模型是对流域水循环过程与能量循环过程的综合模拟,具有较高的模拟精度。对白洋淀流域1956～2000年的径流模拟计算表明:主要水文站的相对误差在5%以内,Nash-Sutcliffe效率系数在0.8以上,可以用于白洋淀流域的水文循环分析。Aiming at the water resources protection within Baiyangdian Lake Basin,a distributed hydrological model——WEP-L(Water and Energy Transfer Processes in large river basins)model is developed herein.The model is just an integrated simulation on both the water cycle and the energy cycle in the basin with a higher precision.The simulation on the runoff processes of this basin from 1956 to 2000 shows that the relative errors from the main hydrological stations therein are less than 5% with the Nash-Sutcliffe efficiency factor is above 0.8,and thenthe WEP-L model can be applied to the analysis made on the water cycle process of Baiyangdian Lake Basin.
