The purpose of the study is to show clearly that substance behavior in the forest area, and to evaluate a purify function of the forest watershed. We observed the rainfall quality in the forest and out of forest, the soil water, and water channel in the forest area and afforest watershed. As the following account a results of the observation. (1) Rainfall in the forest included substance from surface of trunks, branch and leaves. Accordingly, the concentration of T-N, T-P, TOC, and other substance for rainfall in the forest increased more than it out of forest. (2) The pH was gradually neutralized in the soil water, more than a rain of forest. (3) Concentration of a cation substance increased, but the pH was neutralized. Consequently, we estimate that exchange to be buffering activities of soil. (4) In comparison with water quality of forest area, there was the difference of change. (5) Due to an analysis of behavior substance in the soil we applied "trace method ". As it turned out, rainfall quality is affected by the soil which is over about 70%.
