Abstract: The influence of forest on flood parameters in the upstream of Hulan River at the soutbwesternpart of Xiaoxingan Mountains in Heilongjiang province were studied using 17-year series of forestand hydrological data. The results showed that forest reduced floed runoff discharge,and sloweddown flood peay's sharp rise and decline. The effect in terms of unit stock volume is greater thanthat of forest coverage. However,forest influence has its limits.Maximum flcod peak runoffdischarge are determined mainly by maximum storm precipitation,not the forest.The resultsmay serve as reference for precisely recognizing flcod reducing effect of forest and effectivelymanaging flood-prevention forest.
