산성강하물과 해송엽 엽록소의 관련성 = Relation of Acid Depositions and Chlorophyll Concentration in the Pinus thunbergii Leaf

다국어 초록 (Multilingual Abstract)

This study was carried out to investigate the relation of acid depositions and chlorophyll concentration in the Pinus thunbergii leaves. pH of throughfall in Pinus thunbergii forest was 4.20 at industrial sites, and 4.87 at urban sites. Total chlorophyll concentration in leaves were 0.5984 at industrial sites, and 0.6784 at urban sites. The average SO_2 concentration in air was 0.029ppm at industrial sites, and 0.011ppm at urban sites. Correlation between chlorophyll concentration in the Pinus thunbergii leaves and acid depositions was pH (r=-0.8769), NO_3^- (r=0.6983), SO_4^2- (r=0.8929), SO_2 (r=0.8738), and NO_2 (r=0.8523) (p<0.001). respectively. The estimation equation of chlorophyll concentration in the Pinus thunbergii leaf (Y) were given by Y=4.8979 + 0.7698pH + 0.8412SO_4^2 + 0.8673SO_2, + 0.8767NO_2+ 0.8767NO_3^- (r^2=0.8873), which coefficients of determination was 0.88.

본 연구는 공단지역과 도시지역의 산성강하물과 해송엽의 엽록소 함량과 관련성이 있는 인자를 조사하여 그 관련성을 분석하였다. 해송 임분의 수관통과우 pH는 공단지역이 pH 4.20이었고, 도시지역이 pH 4.87이었다. 공단지역과 도시지역의 해송엽의 엽록소 전체 함량은 각각 0.5984와 0.6784로서 공단지역에서 함량이 낮았다. 지역별 SO_2농도는 공단지역이 0.029 ppm, NO_2농도는 도시지역이 0.021 ppm이었다. 해송엽의 엽록소 함량과 산성강하물의 인자 상호간의 상관은 pH (r=-0.8769), NO_3^- (r=0.6983), SO_4^(2-) (r=0.8929)이온, SO_2 (r=0.8738), NO_2 (r=0.8523)이었다 (p<0.01). 해송엽의 엽록소 함량 (Y)에 관여하는 인자의 회귀 방정식은 Y=4.8979 + 0.7698pH + 0.8412SO_4^2 + 0.8673SO_2, + 0.8767NO_2+ 0.8767NO_3^- (r^2=0.8873)이었고, 이때의 설명력은 88%이었다.
