수종분석을 통한 영산강 유역 취락 식생구조 분류

Abstract

Forest vegetation was classified based on the identification of archaeological wood remains and cluster analysis. The wood remains from archaeological contexts represent building materials, fuel, or wooden tools, and it is likely that most of them were sourced from the vicinity of the site. Consequently, the identified wood remains primarily provide information about the composition of the surrounding vegetation. The identification of wood remains from 18 archaeological sites in the Yeongsan River basin, combined with hierarchical cluster analysis, revealed that the wood composition could be categorized into four groups: (1) chestnut tree dominant, (2) pine tree dominant, (3) oak and broad-leaved tree dominant, and (4) oak tree dominant. The presence of the oak and broad-leaved tree dominant groups suggests a warm humid climate and a stable environment without ecological disturbance. Conversely, the appearance of the pine tree dominant group indicates the expansion of secondary forests and selective timber collection. The presence of the chestnut tree dominant group implies the management and cultivation of fruit trees. Notably, the Mahan-Baekje settlements exhibit significantly higher proportions of chestnut wood. This suggests that arboreal cultivation began during the historical period, as the settlements were occupied for longer periods and territoriality became more pronounced. Historical records on Mahan also support the possibility of chestnut cultivation in Mahan-Baekje villages.
