Research Abstract

This study investigated nutrient cycling processes in canopy for two montane forest ecosystems, a beech forest in Japan and a hill evergreen forest in Thailand. The analyzed data showed that, for the beech forest site where Fagus crenata, F. japonica, Tsuga sieboldii dominated, an annual total of throughfall and stemflow K depositions of both Fagus crenata and F. japonica were much larger than that of T. sieboldii. In contrast, for ions such as Mg, Ca, and NO3, the annual total deposition of the evergreen T. sieboldii was much larger than those of the two deciduous beech trees. For the hill evergreen forest, fog occurrence patterns on diurnal, seasonal and inter-annual time scales were clarified and its impact on throughfall generation was discussed.
