Abstract: The longterm water flux monitoring on forested hillslope at Dakeng valley in Xiushui county , south China,showed that the fluctuation of water flux was consistent to that of rainfall pattern and stream flow annual variation. In rainy season,the top 15cm soil was the source of stream water supply,and in nonrainy season watershed runoff was from deep soil layer. Water flux had close relationship with vegetation quality.
