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 ,也可以用于研究气候变化对滦河流域水资源的影响
Brief introduction of the introduction of the United States Geological Survey Center of the development of precipitation runoff system (PRMS). It is considered that the PRMS model has many kinds of simulation functions and contains more comprehensive physical processes. It is a better hydrological model in the world at present. The PRMS model system was transplanted to the Luanhe River Basin, and a preliminary test of its simulation capability was carried out. The results showed that the model system was successfully transplanted in the Luanhe River Basin of China and could reproduce the interannual and seasonal variations of river runoff and other water resources in the Luanhe River basin more accurately. It could also be used to study the impacts of climate change on the Luanhe River Basin The impact of water resources
