We analyzed the surface changes in each forest type based on multi-temporal satellite imagery and climate data analysis on the mountainous regions of Gangwon-do as the case study. As a result of forest type classification using satellite imagery, the area of coniferous forests was decreased, but the area of deciduous forests and the mixed forests were increased. The annual mean temperature in the study area generally risen, and the rise in the annual mean temperature in Wonju particularly displayed a notable rise in 1992. Temperature change in the seasons resulted in a greater rise rate in winter and autumn, compared to other seasons. Such annual mean temperature rise affected the change in forest type distribution, thus directly and indirectly affecting the decrease in the surface area of coniferous forests, and also greatly affecting the expansion of distribution and the growth of mixed forests and deciduous forests. The surface change analysis of each forest type using the post-classification comparison method showed considerable change from coniferous forests to deciduous forests and mixed forests, as a result of the change in forest type based on the increased annual mean temperature after 1990. Furthermore, the change in deciduous forests significantly occurred in mixed forest regions. With these results, future forest type data are expected to be used as the main index of climate change vulnerability assessment, and more accurate quantitative results are expected to be deduced with the assessment of other climatic elements and relationships with different forest types.
