진주성 역사경관림의 생태계서비스에 기반한 공간 분포 특성

초록

This study analyzed the tree structure, total ecosystem services, and spatial distribution patterns of the historical forest within the Jinju Fortress. A total of 822 trees were recorded in the study area, with a canopy cover of 1.272 ha. Pinus densiflora (17.8%) and Zelkova serrata (17.2%) accounted for the largest proportion of individuals. However, when the leaf area ratio and importance values were considered, Z. serrata had the highest values (leaf area, 40.7%; IV, 57.8). This indicates a difference between the dominance based on tree number and the actual functional contribution. The estimated ecosystem services included annual air pollutant removal of 123.1 kg/yr (KRW 8.31 million/yr), carbon storage of 200.7 t (KRW 138 million), annual carbon sequestration of 8.834 t/yr (KRW 6.09 million/yr), oxygen production of 23.56 t/yr. They avoided a runoff reduction of 10.41 ㎥/yr (KRW 29,000/yr). The spatial analysis results showed that air pollutant removal was concentrated in the front area of the National Jinju Museum. In contrast, carbon storage was distributed around the major city gates and Yeongnampojeongsa. Carbon sequestration was concentrated locally around the Yeongnampojeongsa gatehouse, oxygen production was linearly distributed along the northern ridge, and runoff reduction was highest along the fortress wall slopes and ridges. This study confirms that the ecosystem services of historic landscape forests form distinct spatial structures based on their functions. © The Korean Environmental Sciences Society.
