Abstract
The purpose of this study was to ascertain and analyze environmental factors of subgenus Lycoctonum in Korea for conservation and management of rare high land plant species by GIS. We derived the habitat model of Lycoctonum from GPS coordination, habitat factors and digital topology maps. Suitable altitude fur the subgenus Lycoctonum is from 470m to 1320m, and northern slopes(between 15.5 and 36 degrees) are ideal for the Lycoctonum populations. In addition to altitude, slope and aspect, deciduous forest and approximation to water source were found as important factor. Using GIS and the Lycoctonum habitat model, we overlaid elevation, aspect, slope and land cover layers and analyzed buffer from the water source on two topology maps, Yang-Soo and Mock-Dong. After making prediction map for Lycoctonum habitat, we verified the existence of Lycoctonum populations on the predicted sites through field survey. Through this research, we're convinced that GIS software is powerful tool for plants conservation, such as finding unknown habitat or selecting alternative habitat.
국내에 분포하는 진범아속의 식물종 개체군을 대상으로 GIS분석을 통해 서식환경을 분석 검증함으로써 이를 통해 환경변화에 취약한 고산식물종의 보전과 관리를 위한 새로운 방안을 모색하고자 본 연구를 수행하였다. 표본조사와 문헌조사를 바탕으로 작성된 진범아속의 분포도를 중심으로 현장조사에서 정확한 분포좌표와 서식환경 등의 지리적 및 생물학적 인자를 조사하여 이를 바탕으로 수치지형도를 이용하여 서식지 모형을 만들어냈다. 진범아속의 식물개체군은 해발고도
