Abstract:

To research the transforming mechanism of the rainfall in the canopy and soil layer, and the relationship between each water factors, the author investigated the factors for a year. The results showed that throughfall, stemflow and canopy interception made up of 71.63%, 11.54%, 16.30% of the rainfall, respectively, and stemflow, infiltration out of net rainfall accounted for 4.71%, 26.23% respectively, and evapotranspiration from canopy and soil accounted 52.65%, 16.30% for the rainfall respectively. Besides, the author analyzed the distribution characterization of water factors associated with hydrology, and indicated the effect in the hydrologic assessment in the ecological construction of the rubber forest from the aspects of theory and quantized index.
