摘  要:
Fire is an common natural phenomenon in forest ecological systems. There is an close relation between forest fire and forest hydrology. Forest fire effects on hydrology through indirect ways, which mainly represented through vegetation, letter, soil and ecological environment changes after fire and their effects on water cycle ,water quality and aquatic organism. The magnitude of effects is decided by fire intensity and frequency. Low -intensity fire and prescribed burning have little effects on hydrology. But frequent or high intensity fire can lead to the hydrological changes similar to destructive felling.
