摘    要:基于水分能量传输模型(WEP模型),构建了鸭绿江流域基于物理机制的分布式水文模型,该模型综合了水文模型和陆面过程模型的优点,耦合了水分循环和能量过程的模型。以"子流域套等高带"为计算单元,将全流域划分为558个子流域和2 427个等高带,以日为时间步长,对冠层截留、蒸散发、下渗、产汇流等水循环要素过程逐一模拟计算,并以该流域2个主要水文站的还原流量资料为准,对模型进行校准与检验。在校准期与检验期,沙尖子站Nash-Sutcliffe效率系数在0.9左右,水量模拟误差约-4%,梨树沟站Nash-Sutcliffe效率系数在0.94左右,水量模拟误差仅为0.4%左右,表明该模型模拟精度很高,可为流域广义水资源评价、洪水预报预警和国际河流开发利用等提供有力的决策依据。

关 键 词:WEP模型  鸭绿江  国际河流  分布式水文模型  水资源管理

Abstract:On the basis of WEP model,a distributed hydrological model is developed for Yulu River Basin based on physical mechanism,namely WEP-Yalu.With integrating the merits of watershed hydrological models and land surface models and coupling both the hydrological cycle and energy processes,the processes of the hydrological cycle components such as canopy interception,evapotranspiration,infiltration,rainfall-runoff,etc.are simulated in daily time steps one by one by taking the contour strips in a sub-watershed as a...
Keywords:WEP model  Yalu River  international river  distributed hydrological model  water resources management
