Abstract: According to the effects of forest on hydrological process, forest hydrology can be divided into three related aspects:experimental research on the effects of forest changing on hydrological process quantity and water quality; mechanism study on the effects of forest changing on hydrological cycle,and establishing and exploitating physical-based distributed forest hydrological model for resource management and engineering construction. Orientation experiment research can not only support the first-hand data for forest hydrological model, but also make clear the precipitation-runoff mechanisms. Research on runoff mechanisms can be valuable for the exploitation and improvement of physical based hydrological models. Moreover,the model can also improve the experimental and runoff mechanism researches.Areview of above three aspects are summarized in this paper.
