This study was conducted to scientifically identify the trends of healing factor in forests, urban forests, and urban areas to help people choose leisure activities.
Method
From 2019 to 2020, 30 kinds of biogenic volatile organic compounds (BVOCs), 5 kinds of anthropogenic volatile organic compounds (AVOCs), including toluene, and 3 kinds of weather conditions(temperature, humidity, wind speed) were analyzed at forest welfare facilities such as the National Forest Healing Center (MH: Masil Healing Forest Road, MD: Moon Drami Road), urban forest (SF: Seoul Forest), and urban (GS: Gwanghwamun Square). Weather measurements were made from a.m.8 to p.m.18 using MWM-P5 and analyzed using GC/Mass-TD (thermal desorption system) of BVOCs and AVOCs.
Result
The number of BVOCs generated was the highest at 254.73pptv at the MH, followed by 105.64pptv at the SF, 91.65 pptv at MD and 44.35pptv at the GS. AVOCs were the highest at 3.89ppbv in the GS, followed by 2.40ppbv in SF, 0.44ppbv in MH and 0.43ppbv in MD. The discomfort index(temperature humidity index : THI), calculated by temperature and humidity, was lower in forests than in urban areas. On average, the wind speed was higher in the order of the GS, SF, MD, MH.
Conclusion
Forests had higher BVOCs than urban, and AVOCs on average were lower. Also, Forests maintained a more pleasant weather environment than urban areas. The difference in AVOCs appears to be the result of tree species and location. BVOCs appear to have been measured high in heavy traffic urban areas, and the weather environment is believed to be the result of differences in the level of crown densities caused by plants. Through this study, we found that forests are better in terms of air quality and comfort than in urban areas. This can be used as a standard for choosing leisure activities in anticipation of forest healing effects. Keywords: Human health and well-being ID: 3483887 -
DocumentA study on the roles and efficient operations of Korea Forest Conservation Association as a support organization
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.The Korea Forest Conservation Association (KFCA) is a special corporation under the Korea Forest Service, pursuant to Article 46 of Mountainous Districts Management Act. This study analyzes the current functions and state of operations in KFCA for areas with high social value. The main role of KFCA is to act as an expert in investigating the adequacy and validity of the use of forest land that is 30ha or larger; to research for policies that can help upgrade the system for mountainous regions and improve the evaluation of mountainous characteristics. This review provides a broad overview of the major roles and current work status of a forest-specialized organization in Korea, operated as a special corporation under the Korea Forest Service.

DocumentRevisiting leaf microstructural and physical properties for high-efficiency depositional niches of particulate matters
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Current problems and potential solutions to reduce suspended particulate matter (PM) are enormous scientific challenges. Indeed, reducing the vehicle or industrial-driven PM particles still need a guide to discerning an economically viable solution for highly urbanized areas. Therefore, a better understanding of PM capture processes and pathways from both leaf surfaces and waxes would allow for the development of long-term air purification potential and efficiency in the improvement of urban greenspace. Functional traits as biofiltration for airborne PM particle control were calculated using the following species of Aesculus turbinata, Chionanthus retusus, Ginkgo biloba, Liriodendron tulipifera, Magnolia denudata, Styphnolobium japonicum, Taxus cuspidata, Buxus koreana, Euonymus japonicus, and Rhododendron schlippenbachii. Variation in PM adsorption amounts per unit area could be related to the difference in air pollutant concentrations, weather conditions, tree canopy, and adaxial/abaxial leaf surfaces. Leaf micromorphological traits among tree and shrub species were related to PM adsorption; however, the leaf accumulation-PM removal efficiency could be generated through a collaboration of leaf hydrophobic nature and complex surface microstructures such as trichomes. Furthermore, PM retention capacities of leaf surfaces as the main depositional niches for PM particles can be a very important indicator as a valid means to enhance long-term sustainability of context-specific vegetation barriers for urban air pollution abatement. In conclusion, these findings will provide a reference for urban planning and design and can help to develop the improvement of future urban greenspace based on local conditions.
