Influence of Forest Management on the Facility of Cleansing Water Quality in Abies holophylla and Pinus koraiensis Watershed(III) -With a Special Reference to pH and Electrical Conductivity of Rainfall, Throughfall and Stemflow- (전나무림(林), 잣나무림(林) 유역(流域)에서 산림(山林)의 수질정화기능(水質淨化機能)에 미치는 산림시업(山林施業) 영향(影響)(III) -임외우(林外雨), 수관통과우(樹冠通過雨), 수간류(樹幹流)의 pH와 전기전도도(電氣傳導度)를 중심(中心)으로-)

  • This study aims to clarify the effect of forest management practices(thinning and pruning) on water quality to get the fundamental information on the facility of cleansing water quality after forest operation. Rainfall, throughfall and stemflow were sampled at the study sites which consist of Abies holophylla and Pinus koraiensis in Kwangnung Experimental Forest for 6 months from May 4, to November 1, 1999. Average tree height in the management sites increased by 0.5m more than that in the non-management sites in Abies holophylla and Pinus koraiensis, respectively. Increment of average D.B.H. at the management sites grew 3.5cm and 2.6cm more in Abies holophylla and Pinus koraiensis compared with that at non-management sites. Average pH of the total amount for the event in throughfall and stemflow was higher than that of throughfall and stemflow of the beginning of the event at the management and non-management sites. Average electrical conductivity of throughfall and stemflow at the beginning of the event was higher than that of the total amount for the event at management and non-management sites. Water qualities of throughfall and stemflow were buffered more by the management practice in both. The forest management may affect purification of water quality of throughfall and stemflow in Abies holophylla and Pinus koraiensis.
