초 록
본 연구는 2007년 4월에서 6월까지 국내 8기의 석조문화재를 대상으로 환경요인과 엽록소 a 및 색에 따른 생물오염등급을 평가하였다. 엽록소 a 의 경우 16.2~136.6㎍ネ·g-1의 농도를 나타냈으며, 색은 녹색에서 검정색의 범위로 나타났다. 생물오염등급 평가 결과 물걸리삼층석탑과 수타사삼층석탑은 3등급을 나타냈고, 괘석리사사자석탑 및 5개의 문화재는 4등급 이상을 나타냄으로써 생물오염이 심각한 것으로 나타났다. 기중조류는 총 32분류군이 출현하였으며, 이 중 남조강은 16분류군이고, 녹조강은 13분류군이며 규조강은 3분류군으로 나타났다. 엽록소 a와 생물오염등급 간의 상관 분석결과, 상관계수는 0.43을 나타냈다. 엽록소 a와 출현종 간의 상관분석에서 Trebouxia sp.와 Chroococcus bituminosus는 상관계수 0.89와 0.65로써 높은 상관성을 나타냈다. 생물오염등급과 출현종의 경우에는 Chroococcus bituminosus, Aphanocapsa grevillei, Xenococcus acervatus, Chlorella vulgaris 및 Synechocystis pevalekii 등이 상관계수 0.54~0.65의 범위로 높은 상관성을 나타냈다.

ABSTRACT
To evaluate the biological pollution class, Chl-a concentration and color were examined in 8 stone cultural heritages of Korea from April to June 2007. In the case of Chl-a, it had the range of 16.2 to 136.6㎍ネ·g-1, and for the range of the colors, it came out from green to black. As the result of the evaluation, the Three storied stone pagoda in Mulgeol-ri and the Three storied stone pagoda in Suta Temple both showed class 3 and the other 6 stone cultural heritages showed the classes above 4, proving severe biological pollution. The total of 32 aerial algae taxa were found in 8 stone cultural heritages. Out of the 32 taxa, 16 taxa were found in Cyanophyceae, 13 taxa in Chlorophyceae, and 3 taxa in Bacillariophyceae. The correlation coefficient showed 0.43, as a result of the correlation analysis between Chl-a and the biological pollution class. Two among all the aerial algae taxa, Trebouxia sp, and Chroococcus bituminosus, showed high correlation coefficients of 0.89 and 0.65 with Chl-a, in the correlation analysis. High correlation coefficients from 0.54 to 0.65 were shown in a correlation analysis between the biological pollution class and the aerial algae taxa, which are Chroococcus bituminosus, Aphanocapsa grevillei, Xenococcus acervatus, Chlorella vulgaris, and Synechocystis pevalekii.
Key Words: Aerial algae, Biodeterioration, Biological pollution class, Stone cultural heritages
