백두대간 지리산권역의 산림 경관 변화 분석

The purpose of this study is to analyze the changes in the forest landscape in Mt. Jiri Portion of Baekdudaegan as an ecological axis of the country over the past 100 years. A land cover map was created using the 1:50,000 topographic map produced in 1918 and compared with the 2007 land cover map provided by the Ministry of Environment. Spatial analysis using GIS and landscape analysis using FRAGSTATS were performed for the land cover maps in the two periods, and the results are as follows. First, about 147.05 km2 of forest in the Mt. Jiri Portion was converted to other land uses, reducing its area. Among them, the change to agricultural area occupied the largest proportion. Second, in terms of landscape structure, forest fragmentation in the Mt. Jiri Portion of Baekdudaegan has progressed considerably. However, the degree of fragmentation showed internal differences. In the Baekdudaegan Protected Area, changes in forest area and landscape indices were insignificant, while the surrounding areas did not. Third, according to the standardization of the change values of the landscape indices at the Eup/Myeon units constituting the portion, high-level forest fragmentation proceeded in Unbong-eup and Ayeong-myeon, Namwon-si, and Jangye-myeon, Jangsu-gun. These areas are where the Baekdudaegan Protected Area is discontinuously or narrowly designated. In order to restore the integrity of Baekdudaegan as an ecological axis, it is necessary to ensure the continuity of the axis and manage the protected area by designating the spatial extent wider than the present.
