This study aims to clarify the effect of forest management practices(thinning and pruning) in forest hydrological processes on electrical conductivity to get the fundamental information on the facilitation of purifying water qualify after forestry practices. Rainfall, througfall, stemflow, soil and stream water were sampled at the study sites which consist of Abies holophylla and Pinus koraiensis in Kwangnung Experimental Forest for 6 months from March 1 to August 4, 1998. In case of dividing into forest hydrological processes, multiple regression equations of electrical conductivity and total amount of anion, NO3- of throughfall, stemflow, soil water of management site in Abies holophylla shows high significance. And multiple regression equations of electrical conductivity and total amount of anion, SO42-, Cl- of througfall, stemflow, soil water of non-management site in Abies holophylla shows high significance. Multiple regression equations of electrical conductivity and NO3-, before non-rain days of througfall, stemflow, soil water of management site in Pinus koraiensis shows high significance. And multiple regression equations of electrical conductivity and total amount of ion, NO3-, K+, pH, total amount of anion of throughfall, stemflow, soil water of non-management site in Pinus koraiensis shows high significance. Multiple regression equations of electrical conductivity and precipitation, total amount of ion, Na+ of stream water in Abies holophylla and Pinus koraiensis shows high significance. In case of combining into forest hydrological processes, multiple regression equations of electrical conductivity and total amount of cation and anion, Na+, Cl-, and pH in rainfall, throughfall, stemflow, soil and stream water shows high significance.
Key words: forest management, electrical conductivity, throughfall, stemflow, soil and stream water quality
