Chemical Composition of the Sequentially Sampled Precipitation in the Different Forest Stands
상이한 임분에서 분할 채취한 강우의 화학적 조성
Abstract
This study was conducted to investigate vertical movement properties of water quality or chemical composition in three different forest stands (Pinus koraiensis, Larix leptolepis and Quercus spp. stands) in Gwangju-gun and Gyunggi-do. The results were as follows ; The pH range of precipitation was 4.62 ~ 6.72, and the average pH showed 5.74. The relationship of pH among throughfall, stemflow and precipitation showed difference of buffering capacity in tree species. According tree species, acided stemflow and alkalized stemflow had the characteristic value. In three stands, changes of the pH in early rain were larger than those of succeeding rain, except October 1998 and April 1999. Early rain influenced the cation in the acidity and concentration, but succeeding rain influenced the anion such as S
경기도 광주지역의 잣나무, 낙엽송, 활엽수 임분에 있어서 pH 및 용존 원소의 수직적인 이동특성을 구명하기 위하여 강우의 지속에 따른 임외우와 임내우 pH와 강우 중 화학적 조성을 각 단계별로 분할 채취하여 조사, 분석한 결과를 요약하면 다음과 같다. 임외우의 pH의 범위는 4.67~6.72였으며, 평균 pH는 5.74
