Xin anjiang hydrological model was widely used in our humid and semi-humid areas, and achieved good results.After nearly 50 years study, Xin anjiang model has been developed from the single-function of reservoir flood forecasting intomulti-purpose model including hydrological forecasting, water resources management, water and soil resources evaluation, non-point source pollution prediction, climate change and human activities versatile hydrological model studies.And part of its parameterscan be acquired through physical calculation instead of experience. In short, Xin anjiang model is an evolving model system.This paper consists of three parts. The first part is about the brief introduction of Xin anjiang model, which recalls the historical background and the development, as well as introduces the basic principles and architecture; the second part describes the physical meaning of Xin anjiang model parameters and calibration; the third part is about the application of Xin anjiang model in Ying Na River Basin flood control planning.Key Words:hydrological model; Xin anjiang model; Flood forecasting目 录摘 要IAbstractII引 言11 新安江模型简介2
