본 연구는 2008년 6월에서 11월까지 국내 9기의 석조문화재를 대상으로 색에 따른 오염등급의 평가와 생물오염피복도를 조사하였다. 생물오염피복도는 홍천물걸리삼층석탑, 수타사삼층석탑 및 수타사홍우당부도에서 90% 정도로 나타났으며, 선태류의 생물오염피복도가 15~23%의 범위로 생물오염이 가장 심한 것으로 나타났다. 색에 따른 생물오염 등급은 괘석리사사자삼층석탑, 수타사삼층석탑, 수타사홍우당부도가 등급 5로 오염등급이 가장 높았으며, 여주창리삼층석탑이 등급 2로 양호하게 나타났다. 상관분석 결과 생물오염등급과 지의류의 생물오염피복도는 높은 상관성(r=0.91)을 나타냈지만, 기중조류와 선태류의 생물피복도와는 상관성은 낮게 나타나 이에 대한 보완이 필요할 것으로 판단된다. 각 출현종과 생물오염피복도(선태류, 지의류, 기중조류)의 상관분석결과 선태류의 생물피복도와 Cosmarium decedens, Chlorella ellipsoidea, Anabaena fertilissima, Botryococcus braunii, Chroococcus turgidus, Navicula cryptocephala 및 Xenococcus acervatus가 상관계수 0.56~085의 범위로 높은 상관성을 나타냈다. 지의류의 생물피복도는 Trebouxia sp. 및 Chroococcus varius와 상관계수 0.50 및 0.43으로 나타났으며, 기중조류의 생물오염피복도는 Achnanthes laterostrata 및 Ulothrix zonata와 상관계수 0.76 및 0.57의 상관성을 나타냈다. 생물오염피복도와 상관성이 높은 기중조류는 출현 경향성이 대체로 뚜렷하게 나타나, 지표종으로 유용하게 사용될 수 있을 것이라 판단된다.

ABSTRACT
This research was to examine the biological pollution class by color of the polluted section and calculate the biological pollution coverages of 9 stone heritages in Korea, from June to November 2008. Three storied stone pagoda in Mulgeol-ri, Hongcheon, Three storied stone pagoda in Suta Temple and Stupa to Hongudang in Sutasa Temple showed 90% biological pollution coverage and each stone cultural heritages showed 15~23% range of Bryophyte coverage, proving severe biological pollution. The Four-lion three storied stone pagoda of Gwaeseok-ri, Three storied stone pagoda in Suta Temple and Stupa to Hongudang in Sutasa Temple showed the worst biological pollution class by color of class 5. Three storied stone pagoda in Chang-ri showed satisfactory level of class 2. The result of the correlation analysis between biological pollution class and the biological pollution coverage of lichen showed high correlation coefficient of 0.91, however, the correlation analysis between biological pollution class and bryophyte or aerial algae coverage showed the low correlation coefficient. Eight taxa among all the aerial algae, Cosmarium decedens, Chlorella ellipsoidea, Anabaena fertilissima, Botryococcus braunii, Chroococcus turgidus, Navicula cryptocephala and Xenococcus acervatus showed high correlation coefficient of 0.56~0.85 with biological pollution coverage of bryophyte, in the correlation analysis. The correlation coefficient between biological pollution coverage of lichen, Trebouxia sp. and Chroococcus varius, had a range between 0.43 to 0.50. The correlation coefficient between biological pollution coverage of aerial algae, Achnanthes laterostrata and Ulothrix zonata showed a range of 0.57 to 0.76. Since the aerial algae with high correlation between biological pollution coverage showed clear appearance tendency, they can be used as indicator.
Key Words: Aerial algae, Biological pollution coverage, Biological pollution class, Biodeterioration
