We examined water flux, concentrations and contents in nutrients in precipitation, throughfall, stemflow and soil solution in natural deciduous hardwood forest(Quercus variabilis and Q. mongolica) in Chunchon, Kangwon Province. The volume of throughfall was 2¡­3% higher in Q. variabilis than in Q. monglica while volume of stemflow, Ao, A and B soil solution was 10¡­15% higher in Q. variabilis compared to Q. monglica. Concentrations of K/sup +/ increased in throughfall H while concentrations of Ca/sup 2+/, Mg/sup 2+/ and NO©ý/sup -/ increased in Ao soil solution. The former might be related to the canopy leaching and the latter related to leaching and nitrification in Ao horizon. Nutrient concentrations in throughfall, Ao, A and B soil solution decreased with increasing amount of water and especially the decreases in concentrations of K/sup +/, Mg/sup 2+/ and Cl/sup -/ were significant. Nutrient concentrations of Ca/sup 2+/ in Ao soil solution was 1.5 times higher in Q. variabilis than in Q. mongolica. However, there were no significant nutrient concentration differences in throughfall, stemflow and A and B soil solution between the two forest types. Stemflow was less than 10% of total water volume (throughfall + stemflow) to the forest floor, and contribution of stemflow to nutrient cycling seemed to be low in the study forest.
