摘要 Forest management is key to maintaining and increasing carbon sinks in forests. In the context of climate change mitigation, the exact number of carbon sinks associated with forest management is estimated as the additionality of activities, which means net greenhouse gas (GHG) removals or carbon sequestration over and above those that would have arisen even in the absence of a given activity. This study analyzes the spatial and temporal patterns of forest management activities to present the forest management ratio, of managed area to the total forest area, as an indicator of additionality in forest management in South Korea. Forest management activities based on the IPCC guidelines were spatially constructed, and the characteristics of managed and protected forests from 1990 to 2019 were analyzed. The results indicate that between the managed forests and roads, 90% of the management activities in private forests occurred within 214 m of the road, and 70% of the activities in the national forest occurred within 234 m. Management took place in easy-to-access places with gentle slopes and low elevations. The proportion of protected forests above 40 years old is 87.2%, higher than the average of 72% in South Korea, and it is expected that most forests will age and their carbon absorption capacity will decrease by 2050. The area of tree planting and thinning is approximately 290 thousand ha per year, which could potentially increase the forest management ratio by up to 4.5% per year. However, the actual increase was at an average of 1.4%, owing to the omission of exact information on management activities, such as spatial coordinates and overlapping practices in the same management unit. The forest management ratio in South Korea as of 2019 was 53.4%; therefore, the amount of GHG removal in the forest sectors was 53.4% of total absorption per year. Thus, it is necessary to make efforts to increase the ratio to enhance the contribution of forest sectors to climate change mitigation for the country. View Full-Text
