This study was conducted to investigate vertical movement properties of precipitation passing foreststands (Pinus densiflora and Pinus rigida stands) in Chunchon, Kangwon-do. The results were asfollows: The pH range of precipitation was 4.08~7.08, and the average pH showed 6.2. 0.7. Theaverage pH of the Pinus densiflora stand showed that the stemflow was 5.9. 0.9, and the throughfalwas 6.0. 0.8. The pH value of stemflow and throughfall in the Pinus rigida stand was lower than forthe Pinus densiflora stand. Changes of the cation concentrations in two different stands, Ca2+,increased more than the Mg2+, K+, and Na+ ions. Anions, SO42- and NO 3- increased more than Cl-.Leaching and washout for each species differed by precipitation and influence of tree organs (crown,branch, stem, etc.).
