Research Progress on Forest Hydrological Model

Forest hydrological model is built around the research content of forest hydrology.The model simulates the data needed in the process of forest hydrology,which can not only predict the future forest hydrological situation,but also supplement the historical incomplete hydrological data.In order to promote the protection and development of forest resources and water resources,this paper divided the model types by three methods,built the model around the five contents of Forest Hydrology Research（forest canopy interception,watershed runoff,soil water movement in forest land,forest evapotranspiration,and water quality）,and further discussed the development prospect of forest hydrology model in the future.At present,there are two main problems in forest hydrological model:one is the lack of accuracy in model checking;Second,there is a lack of historical hydrometeorological data.Therefore,it is necessary to strengthen the research of forest hydrological model,determine the classification method of the model,improve the accuracy of the model,solve the problem of lack of historical hydrological and meteorological data,and further promote the development of forest hydrology.
