Abstract

The estimation model was constructed to estimate the evapotranspiration and canopy interception from the forest stand using the parameters showing the forest structure such as stem density, tree height and leaf area index. This model is expected to have the ability to estimate the effect of forest management such as stem thinning and leaf amount control. Comparing the calculated rate by this model and the observed rate in previous studies, the model can estimate the evapotranspiration and canopy interception. The effect of air temperature rise on the potential water resources was also estimated. Its decrease ratio was calculated to be around 11–13%.
