발왕산 산림유전자원보호구역의 관속식물상 및 식생구조 특성

초록

This study was carried out to investigate the flora of vascular plants and vegetation structure of Forest Genetic Resources Reserve on Mt. Balwang, located in Pyeongchang-gun, Gangwon-do. The survey was carried 5 times from March to September 2023. Using vegetation data from 67 sites, forest vegetation types were classified through Two-way Indicator Species Analysis (TWINSPAN), and their ecological characteristics were analyzed using mean relative importance value, species diversity, and CCA. The Result of vascular plants revealed a total of 320 taxa, consisting of 81 families, 186 genera, 283 species, 7 subspecies, 28 varieties and 2 forms. Among them, Korea endemic plants were 13 taxa, and 5 taxa were identified as rare plants. Moreover, there were 118 taxa of floristic target species and 22 taxa of the naturalized plants. In the 67 plots of Mt. Balwang, vegetation data were classified into 5 types using the TWINSPAN method. The species diversity was relatively high at 2.222 in VT2 compared to other vegetation units, and it also exhibited the highest values in terms of richness and evenness. According to the CCA analysis, environmental factors affecting the distribution of vegetation were found to be correlated with altitude, species diversity, and rock exposure. The physiognomic vegetation map were classified into 8 community in total.
