Abstract

Due to the effects of climate change, many coniferous trees such as Korean fir and spruce are dying, and the importance of sustainable management of Jirisan National Park is increasing. In this study, we conducted a study on Jirisan national park to identify areas requiring priority management to respond to climate change. We introduced an advanced technique that comprehensively utilizes the results of carbon sequestration changes based on the KO-G-Dynamic model and vegetation value assessments derived from high-resolution satellite images. The results showed that the areas with decreased carbon uptake in Jirisan national park are gradually expanding compared to the past, attributed to increased mortality and reduced grwoth volume due to aging. In addition, among the areas with decreasing carbon uptake, forest areas with high conservation value, such as temperate zone evergreen broadleaf forests and deciduous broadleaf forests, were identified as priority management areas for climate change response. This research methodology is expected to contribute to establishing optimized climate change response measures for forest areas, including national parks, in the future.
