| 概要 | Korea is located in the middle latitude of East Asia. The geographic location of Korea brings four distinct seasons of hot and humid summer and cold and dry winter, providing environments for high bio...diversity. About 70% of the land belongs to mountainous regions, which supports diverse habitats and high biodiversity. However, long history of human residence in Korea implies high anthropogenic disturbances, resulting in lower biodiversity than its potential. Diverse climatic and topographic characteristics of Korea support diverse forest disturbances as well. Wildland fire, landslide and insect pests and diseases are three major forest disturbance types in Korean forests. The wildland fire and landslides are closely related to seasonal climate as wildland fire is a dominant disturbance in spring, whereas landslide and soil erosion are prevalent in summer. They are more affected by precipitation than temperature. Changes in damaged area by insect pests and diseases reflected changes in tree species and forest types. As broadleaved forests increased with replacing coniferous forests, insect pests and diseases on broadleaved species increased with more diversified agents. Korean forests have been adapted to its seasonal climatic changes and disturbances. Climate change seems to confuse seasonal weather patterns and alter disturbance patterns, threating forest ecosystems in Korea. More active research, strategies and management are necessary to conserve and maintain forest ecosystems in Korea.続きを見る |
