一般講演（口頭発表） D02-09 （Oral presentation）
DOC, TDN, DIN (NH4-N, NO2+NO3-N), DON concentrations and flux were measured in bulk precipitation, throughfall, stemflow and litter leachate from two forest types – Takayama deciduous forest located far away from city centre, and in Mt. Kinka evergreen broad-leaved forest located near city centre. The volume of stemflow in Mt. Kinka was approximately twice the volume in Takayama forest, while the volume of other water fluxes was almost same in the two sites. These may due to the difference of bark water storage capacities between two sites. The average bulk precipitation DOC concentration and litter leachate DOC concentration in Mt. Kinka was higher than that in Takayama. While stemflow and throughfall DOC concentrations in Takayama were higher than in Mt. Kinka during growing season, which implied that there was more DOC leaching from stem and canopy in the deciduous forest than in the evergreen forest. Significant differences were found in stemflow DOC concentration between coniferous and deciduous trees in Takayama. In Mt. Kinka, annual mean TDN concentration in throughfall was twice as it in bulk precipitation, moreover, the monthly TDN flux of throughfall was more than twice as TDN flux of bulk precipitation, which suggests the wet deposition was less than the intercepting dry deposition by forest canopy.
