Description

Thinning is a major tool in the management of plantation, but its effects on water cycle are yet to be evaluated well. In this study, we investigated the changes in evapotranspiration, including stand transpiration, canopy interception loss and evapotranspiration from forest floor, after thinning in Japanese cedar and Japanese cypress plantation. The reduction of daily stand transpiration in the Japanese cedar and cypress stands after thinning under the same condition of microclimate were comparable to the changes in total sapwood area. It implies that sapwood area is a primary determinant of stand transpiration. Canopy interception ratios were decreased 3 % and 5 % after thinning, respectively. Evapotranspiration from forest floor was dramatically increased, because of large increase in radiation in the forest. Thus, we obtained the changes in annual evapotranspiration and its components at catchment scale by using observation and models.
