Abstract

This study was conducted to prepare basic data by analyzing the biological values and environmental factors of algific talus slope in order to respond to climate change due to the greenhouse effect, and to establish plans for forest biodiversity preserving and managing. Meteorological information was measured and the flora of vascular plants were investigated for six algific talus slope by seasonally from 2020 to 2021. As a result of the investigation, the temperature of all 6 algific talus slope was lower than that of the area where the algific talus slope was located in summer, and flora was 101 families, 350 genera, 621 species, 18 subspecies, 57 variants, 7 varieties, 703 taxa. In sum, it is judged that the algific talus slope has sufficient reasons and value to be preserved because it has excellent micrometeorological value from the cold wind blowing in summer and phytogeographical value in which various plants live in a small area. However, in spite of such an important area, the management of algific talus slope is insufficient, and the algific talus slope is damaged or the ecosystem of the algific talus slope is disturbed. Therefore, it is necessary to establish a systematic conservation and management plan by designating algific talus slope as a forest genetic resource reserve and OECM.

본 연구는 온실효과로 인한 기후변화에 대응하고자 산림생물다양성특정지역(풍혈)에 대한 생물학적 가치와 환경요인을 분석하여 풍혈에 대한 기초자료를 작성하고 이를 통해 산림생물다양성 보전 및 관리를 위한 방안을 수립하고자 수행되었다. 국내 분포하는 풍혈 25개소 중 지형학적 유형에 따라 분류한 애추형, 동굴형, 함몰형 풍혈 6개소를 선정하여, 지하에서 바람이 불어나오는 전석지를 경계로 구분하여 풍혈 내·외부로 나누어 2020년부터 2021년까지 계절별로 기상정보와 관속식물상을 조사하였다. 여름철에 6곳의 풍혈 모두 풍혈이 위치하는 지역보다 기온이 낮게 나타났다. 6곳의 풍혈의 관속식물은 101과 350속 621종 18아종 57변종 7품종 703분류군으로 조사되었다. 한반도 특산식물은 29분류군, IUCN 지정 희귀식물은 위급종(CR) 5분류군, 위기종(EN) 3분류군, 취약종(VU) 4분류군 등 총 22분류군이 확인되었다. 식물구계학적 특정식물은 V등급 4분류군, IV등급 27분류군, III등급 48분류군 등 총 168분류군, 북방계식물은 129분류군, 한반도 기후변화 적응 대상 식물 300의 북방계식물 100종 중 총 22분류군이 확인되었다. 침입외래식물은 48분류군, 생태계교란식물은 7분류군이 확인되었으며, 귀화율은 6.8%로 나타났다.
