Abstract

Soil characteristics by site types (slope, topography and stand) were analyzed to provide the basic information for sustainable management of Nari basin in Ulleung Island. The content of total N of Nari basin was lowest at the north slope, this site had also significantly low soil pH and content of available P. The result of soil pH and content of total N analysis by topography, ranged from 5.13 of summit to 5.59 of plain and from 0.63% of plain to 0.87% of hill, respectively. Soil pH, content of total N and available P by stand were significantly different, which showed that stand types are more significant in explaining the soil properties. Available P content by slope, topography and stand ranged from 2.79 to 8.46 ppm, 3.99 to 8.46 ppm and 5.03 to 11.59 ppm, respectively. It was concluded that forest soil around Nari basin has relatively low available P content compared to other forest soil.

울릉도 나리분지 주변의 지속가능한 관리를 위한 기초정보를 제공하기 위하여 입지유형별 (사면, 지형, 임분) 토양특성을 분석하였다. 사면별 토양분석 결과, 토양 pH와 유효인산 함량은 북사면이 다른 조사지에 비해 유의적으로 낮게 나타났으며 전질소 함량은 나리분지가 가장 낮았다. 지형별 분석 결과, 토양 pH는 산정의 5.13에서 나리분지의 5.59, 전질소 함량은 평지인 나리분지의 0.63%에서 산복의 0.87%의 범위에 있는 것으로 나타났다. 임분별 토양특성 중 토양 pH, 전질소 및 유효인산 함량은 전조사지에서 유의적인 차이가 나타나 식생의 영향을 직접적으로 받는다는 것을 알 수 있었다. 특히, 유효인산 함량은 사면별로는 2.79-8.46 ppm, 지형별로는 3.99-8.46 ppm, 임분별로는 5.03-11.59 ppm으로 나타나 일반 산림토양과 비교하면 아주 낮은 것으로 분석되었다.
