In order to estimate dry deposition and leaching rate dividedly onto the forest canopies, model calculation using material balance method (SO42- was used as model substances) based on throughfall measurements was investigated at the four forests of Cryptomeria japonica, Quercus serrata, Q. myrsinaefolia and Chamaecyparis obtusa in Kobe city. Dry deposition rate on the four forest canopies was higher than that on open field, and the rate onto C. japonica forest was much higher than those of other forests. In this forest, total flux of acidic deposition was about three times larger than the incident deposition. K+, Mn, Mg2+ and Ca2+ were found to be leached from the four forest canopies, whereas H+, NH4+, Zn, Cu and Pb were adsorbed in these canopies. And the orders ofthe leaching velocity were K+ > Mn, Mg2+> Ca2+, and Q. serrata > C. japonica > C.obtusa. These results were agreed to those of the leaching experiments using leaves ofabove trees. The fact that a significant correlation found between the leaching rates of Mn, Mg2+ and Ca2+ and the dry deposition rate of H+ indicate that the input of acidic deposition onto forest canopies had effects on nutrient cycling in the forest ecosystems. Above results show that our method based on both throughfall measurements and model calculation is available to the estimation of dry deposition and leaching rate onto the forest canopies.
