| This research was conducted to evaluate the effect of forest management practices on pH and electrical conductivity to get fundamental information on water purification capacity after forest operation. Rainfall, throughfall and stemflow¡¡were¡¡sampled at the study sites which consist of Abies holophylla and Pinus koraiensis¡¡in Gwangreung Experimental Forest for S months from May to November 1999. Mean pH of the throughfall of the beginning of the event was higher in management (thinning and pruning) sites of Abies holophylla and Pinus koraiensis stands than nonmanagement site of Abies holophylla and Pinus koraiensis stands. In addition, pH of the throughfall of the total amount of the event showed similar trends which are higher pH in the management sites compared with the non- management sites. This result indicates that managements such as thinning and pruning improve tree butler capacity of rainfall pH. According to the linear regression results, pH of the throughfall of the total amount of the event in non-management sites = 0.735${ imes}$pH of the throughfall of the beginning of the event in non-management sites+1.849 ($R^2;=;0.82$) and pH of the throughfall of the total amount of the event in management sites= 0.863${ imes}$pH of the throughfall of the beginning of the event in management sites +1.0242 ($R^2;=;0.87$). In case of stemflow pH, pH of the sternflow of the total amount of¡¡the event in non-management sites = 0.53${ imes}$pH of the stemflow of the beginning of¡¡the event in non- management sites+2.7709 ($R^2;=;0.64$) and pH of the stemflow of the total amount of the event in management sites = 0.5854${ imes}$pH of the stemflow of the beginning of the event in management sites+2.7045 ($R^2;=;0.65$). Electrical conductivity (EC) of the throughfall of the beginning and total amount of the event was highest in non- management site in Abies holophylla, followed by management sites in fsies Abies holophylla, non-management site in Pinus koraiensis, and management sites in Pinus koraiensis stands, respectively. According to the linear regression results, EC of the throughfall of the total amount of the event in non-managementsites = 0.4045${ imes}$EC of the throughfall of the beginning of the event in non-management sites+26.766 ($R^2;=;0.69$) and EC of the throughfall of the total amount of the event in management sites = 0.6002${ imes}$EC of the throughfall of the beginning of the event in management sites+8.0184 ($R^2;=;0.54$). In case of stemflow EC, EC of thestemflow of the total amount of the event in non-management sites = 0.6298${ imes}$EC of the stemflow of the beginning of the event in non-management sites+11.582 ($R^2;=;0.72$) and pH of the stemflow of the total amount of the event in management sites =0.602${ imes}$pH of the stemflow of the beginning of the event in management sites+20.783($R^2;=;0.49$). |
