초록

This study evaluated campus forest ecosystem services using an i-Tree Eco at the College of Agriculture and Life Sciences, Gyeongsang National University. In total, 385 trees were surveyed, with Diospyros kaki, Acer palmatum, and Chamaecyparis pisifera as the most frequent species. The forest removed an estimated 38.2 kg of air pollutants annually, valued at 662,380 KRW, with O3 accounting for the largest share (48.2%) and PM2.5 contributing to the second-highest economic value despite the lower removal amounts. Carbon storage and sequestration were estimated at 104.6 tons and 2.767 tons/yr, respectively, equivalent to 72.2 and 1.91 million KRW, respectively. Liriodendron tulipifera contributed the most, representing 13.9% of total storage and 19.9% of annual sequestration. An estimated 7.37 ton/yr of O2 was produced. The stormwater runoff reduction effect was estimated at 67.5 m3/yr (12.1 m3/ha). The predominance of ornamental species may partially explain the relatively modest runoff regulatory capacity per unit area. These findings provide useful insights for campus landscape management and may inform urban forest planning strategies aimed at enhancing ecosystem services in highly urbanized areas.
