Abstract

This study was carried out to provide basal information on factors effected the decline of Pinus thunbergii by analysisof, the content of chlorophyll, and acid deposition through stepwise regression analysis. pH in throughfall at industrial area was 4.65 in the spring and 4.72 in the fall. On the contrary, pH at rural area was measured 5.32 in the spring and 5.34 in the fall. EC of rain fall at industrial area was $262.30{\mu}s$, However, there was $47.72{\mu}s$ at control area. Of anions, the concentration of ${NO_3}^-$ was $52.13mg/{\ell}$ at industrial area and $37.85mg/{\ell}$ at area. The concentration of ${SO_4}^{2-}$ was $57.89mg/{\ell}$ at industrial area and $36.21mg/{\ell}$ at area. Of the concentration of leaf chlorophyll in Pinus thunbergii, chlorophyll a was 0.2378 but control area was 0.4378. Also the content of chlorphyll b was 0.2097 and control area was 0.2345. The degree of decline of Pinus thunbergii forest was 2.97 at industrial area and 1.20 at area. We carried out a correlation analysis between the degree of decline and the concentration of ions, $SO_2$, and $NO_2$ in Pinus thunbergii forest. As a result, there was a negative correlation (r=-0.8672) between rain acids, and a positive correlation between $SO_2$ concentrations (r=0.8924) and between $NO_2$ concentrations (r=0.8428) in air. The correlations among acid depositions at level of 1% were pH (r=-0.8672), ${NO_3}^-$(r=0.6996), ${SO_4}^{2-}$(r=0.8497), $SO_2$ (r=0.8924), and $NO_2$ (r=0.8428).

본 연구는 대기오염으로 인한 $SO_2$$NO_2$ 그리고 산성비 등의 건성 및 습성강하물의 영향을 받고 있는 공단지역 주변 산림과 대조지역의 해송림에서 해송림의 쇠퇴도 사이에 상관분석과 단계적 회귀분석을 통하여 해송 잎의 쇠퇴와 엽록소 함량에 가장 영향을 미치는 인자를 구명하였다. 수관통과우의 pH는 도시공단지역이 봄철 4.65, 가을철 4.72이었고, 대조지역이 봄철 5.32과 가을철 5.34였다. 음이온 성분 중에서 ${NO_3}^-$의 농도는 도시공단지역이 $52.13mg/{\ell}$ 대조지역은 $37.85mg/{\ell}$이었다. ${SO_4}^{2-}$ 함량은 도시공단지역이 $57.89mg/{\ell}$, 대조지역이 $36.21mg/{\ell}$이었다. $Ca^{2+}$의 농도는 도시공단지역이 $27.27mg/{\ell}$, 대조지역이 $9.48mg/{\ell}$ 이었다. 해송 잎의 엽록소 a의 함량은 도시공단지역이 0.2378이었고, 대조지역은 0.4378이었다. 해송의 쇠퇴도는 도시공단지역 2.97, 대조지역 1.20이었다. 해송 임분의 쇠퇴도와 강우의 이온성분, $SO_2$, $NO_2$ 농도와 상관분석 결과에서 강우산도 상호간에는 부의 상관(r=-0.8672)이었고, 대기 중 $SO_2$ 농도는 정의 상관(r=0.8924)이었으며, $NO_2$ 농도도 정의 상관(r=0.8428)이었다. 이러한 산성강하물 상호간의 상관관계는 pH(r=-0.8672), ${NO_3}^-$(r=0.6996), ${SO_4}^{2-}$(r=0.8497), $SO_2$ (r=0.8924), $NO_2$(r=0.8428)는 1% 수준에서 상관이 있었다.
