气候变化对滦河流域水资源影响的水文模式模拟 (Ⅰ)降水径流模式系统(PRMS)介绍及其在滦河流域的移植

Simulation of Influence of Climate Change on Water Resource over Luanhe River Valley Using a Hydrological Model (I): Introduction of Precipitation-Runoff Modeling System(PRMS) and Its Replant over Luanhe River Valley

简单介绍了引进美国地质勘查中心发展的降水径流模式系统 (PRMS)。认为PRMS模式具有多种模拟功能 ,包含的物理过程也较全面 ,是当前世界上较好的水文学模式。将PRMS模式系统移植到滦河流域 ,并对其模拟能力进行了初步检验。结果表明 ,模式系统在我国滦河流域的移植比较成功 ,而且能够较真实地再现滦河流域河川径流量及水资源其它分量的年际及季节变化 。

We briefly introduce theprecipitation runoff modelingsystem (PRMS) of U.S. Geological Survey. The model is a better hydrological modelin current world.It includes many physical processesand can be used to simulate several hydrological processes. The PRMS is replanted to Luanhe river valley, and primarily test its modeling capability. The results show that the replant of the model is successfulover the Luanhe river valley. The model can truly reproduce the annual and seasonal variationof the channel runoff and the other variables of water resource over Luanhe river valley. We can use the model to study the influence of the climate change on the water resource over Luanhe river valley.
