- This research was conducted to improve the vegetation survey method using hyperspectral imaging and LiDAR techniques. Using Ocean FX, spectral data of seven representative species of Mount Hambaek were acquired, and hyperspectral image data of Mount Hambaek were acquired using AisaFENIX 1K and microCASI-1920 sensors. For spectral data and hyperspectral image data, tree species data were extracted using the Spectral Angle Mapper (SAM) technique, and data such as tree species location, height, and diameter at breast height were extracted through LiDAR data. the results of an investigation A total of 39,351 trees were surveyed in the Mount Hambuk area, with 25,930 trees (65.9%) in Quercus mongolica, followed by Larix kaempferi with 6,805 trees (17.3%), Alnus sibirica with 3,625 trees (9.2%), Pinus dendiflora 1,764 trees (4.5%), Pinus koraiensis 605 trees (1.5%), Pinus rigida 405 trees (1.0%), and Betulaermanii 217 trees (0.5%), As a result of selecting 28 representative colonies to be surveyed and conducting on-site verification, 27 out of 28 colonies were found to be 96.43% accurate.

Abstract

- This research was conducted to determine the biodiversity of higher fungi at the supersite of Mt. Jeombong from July to October 2017 during the second long-term ecology research by the National Institute of Ecology under the management of the Ministry of Environment of Korea. Forty-three families, 74 genera, and 130 species of higher fungi were found within the permanent square area of Mt. Jeombong and a 10 m radius of the ecological flux tower. Russulaceae (54 species, 21.9%), Amanitaceae (17 species, 6.9%), and Boletaceae (17 species, 6.9%) were the top three species taxa found in mycorrhizal mushrooms. Mycenaceae (nine species, 8.5%), Polyporaceae (11 species, 4.5%), and Strophariaceae (11 species, 4.5%) were the top three species taxa found in saprophytic mushrooms. These results were analyzed and compared with those of previous fungal mushroom studies.
