摘要
在森林生态系统中，火是一种相当普遍的自然现象，森林火灾和森林水文二者有着密切的关系。森林火灾对水的影响是间接的，主要表现为火烧后植被、地被物、土壤以及生态环境的改变影响水分循环过程、水质、水生生物等方面。火对水文影响有大有小，它取决于火的强度和频度。轻度野火或计划火烧对水文可能不产生明显影响，但是，频繁或严重的野火却可以造成乱砍滥伐所导致的类似水文变化。
Fire is a common natural phenomenon in forest ecological systems. There is a 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.
