Influence of soil organic matter contents on soil water characteristics of forests on east slope of Gongga Mountain

Abstract

By testing soil organic matter (SOM) contents, soil water contents (SWC) within low suctions, and saturated infiltration rates of samples taken from east slope of Gongga Mountain of China, the enhancive effects of SOM contents on SWC within low suctions and saturated infiltration rates were quantified. The simulated functions might be applied on regional experience forest-hydrology model. The improving function of protecting forest floor and increasing SOM contents on forest ecosystem hydrological effects were also embodied.
