Abstract: Urban forests have been emerging as a solution against climate change in a city. Urban forests provide multiple benefits of environmental and ecological services such as carbon storage & sequestration, air pollutant and runoff reduction, and heatwave regulation. This study aims to evaluate the environmental & ecological value of urban forests at the PM measurement networks (aican.nifos.go.kr) using i-Tree Eco and to identify the relationship with meteorological conditions. A total of 3,342 trees of 47 species were survyed at twelve study sites. The main tree species were Ginkgo biloba, Zelkova serrata, and Platanus occidentalis, which are mainly planted as street trees. According to the i-Tree Eco analysis, the average annual ecosystem service value were approximately estimated as KRW 10 milion per one site. The correlation between the monthly PM2.5 reduction (kg) of a single street tree and the meteorological conditions (temperature, humidity) of the measurement networks showed that PM2.5 reduction was closely related to meteorological conditions (temperature r=0.88, p<0.001; humidity r=0.74, p=0.006). The greatest reductions in PM2.5 occurred during the summer seasons when average temperatures and humidity were higher. These results could be utilized as a basis for future urban forest planning, and are expected to contribute to increasing public awareness of the ecosystem services of urban forests.
