Abstract
This study investigated pH values and EC changes of rainfall and stemflow were investigated for 5 tree species such as Pinus koraiensis, P. densiflora, Larix leptolepis, Quercus variabilis and Q. mongolica in the Experiment Forests, College of Forest Science, Kangwon National University. The results were as follows; 1. Mean month pH values of stemflow were much lower than those of rainfall. Among tree species, pH values of the coniferous such as P. densiflora, P. koraiensis and L. leptolepis were lower those of the deciduous such as Q. mongolica and Q. variabilis. Mean month pH values of stemflow ranged from 3.23 to 5.03 (average : 4.23) for P. koraiensis, 3.57 to 5.16 (average : 4.36) for P. densiflora, 3.41 to 6.69 (average : 4.45) for L. leptolepis, 3.86 to 6.11 (average : 4.70) for Q. variabilis and 4.39 to 6.13 (average : 5.18) for Q. mongolica. 2. Mean month EC of the coniferous species was 1.5 to 2 times higher than that of the deciduous species. Mean month EC of stemflow for P. koraiensis, P. densiflora, L. leptolepis, Q. variabilis and Q. mongolica was ranged from 29.0 to
강원대학교 산림과학대학 부속연습림의 대표적 조림수종인 잣나무와 낙엽송, 천연생 활엽수인 신갈나무, 굴참나무와 침엽수인 소나무 등 5종류, 각 2본씩 합계 10본의 강우와 수간류의 pH값 및 EC값을 분석한 결과는 다음과 같다. 1. 수간류의 월평균 pH값은 강우의 pH값보다 낮게 나타났으며, 침엽수인 소나무, 잣나무 및 낙엽송 보다 활엽수인 굴참나무와 신갈나무의 pH값이 높게 나타났다. 수종별 pH값은 잣나무 3.23~5.03(평균 : 4.23), 소나무 3.57~5.16(평균 : 4.36), 낙엽송 3.41~6.69(평균 : 4.45), 굴참나무 3.86~6.11(평균 : 4.70), 신갈나무 4.39~6.13(평균 : 5.18)였으며, 강우의 pH값과는 직접적인 상관이 없는 것으로 나타났다. 2. 수간류의 월평균 EC값은 침엽수종이 활엽수종보다 약 1.5~2배이상 높게 나타나, 잣나무
