국립공원 육상생태계 생태·환경적 차이에 따른 탄소저장량 특성 연구

Abstract

This study aimed to assess carbon storage by establishing 222 fixed survey plots in 22 national parks and analyzing the plant ecological characteristics of the survey areas to determine any relationships. To achieve this, we analyzed plant community structure and species diversity indices based on survey information for each plot. Initially, the plant communities for the entire survey plots were classified into four types. Group I was characterized as the Taxus cuspidata-Abies koreana community, Group II as the Acer pictum community, Group III as the Quercus-Pinus densiflora community, and Group IV as the Pinus strobus community. Among these four types, Groups I, II, and III were distinguished by elevation, and we observed a linear arrangement along the second axis as the carbon storage in the deciduous layer increased, indicating that Groups I, II, and III could be differentiated based on carbon storage in the deciduous layer. Soil carbon storage showed a similar trend, while woody carbon storage did not exhibit a clear group-based trend. Furthermore, when examining the relationship between carbon storage and species diversity, we found a weak positive correlation between soil carbon storage and species diversity, but no significant correlation with vegetation carbon storage. However, it's important to note that these results only reflect the findings based on the survey results for trees with a diameter at breast height of 6 cm or larger and sub-canopy layer trees. Additional data collection for shrub and ground cover plant species is necessary to further develop these findings.
