초록

본 연구는 산음 자연 휴양림을 대상으로 임상별, 월별, 시간별 산림공기를 포집하여 피톤치드 농도의변화경향과 기상인자와의 상관성을 구명하여 휴양정보를 제공하는 것이다. 측정은 2016년 5월 말부터 2017년5월 중순까지 한 달에 2회, 하루 중 일출, 남중, 일몰 3회 실시하였다. 측정대상 임상은 침엽수림, 활엽수림, 침· 활혼효림이며, 공기포집용 미니펌프(MP-Σ30N)와 공기포집튜브(Tenax Ta Tube)를 이용하여 포집한 산림공기를 TDS/GC/MSD 방법으로 분석하였다. 온도, 습도, 풍속은 기상청 자료를 사용하였다. NVOCs는 4월부터상승하여 6월에 소폭 하락하나 9월까지 상승했다. 9월에 정점에 도달한 후 겨울로 갈수록 하락하였다. 임상별NVOCs 연평균 농도는 활엽수림 2.548μg/m3, 침·활혼효림 2.517μg/m3, 침엽수림 2.078μg/m3 순으로 높게 나타났다. NVOCs 주요 성분은 Farnesene > α-Pinene > Limonene > Myrcene > Cymene > Camphene > β-Pinene > Sabinene 순으로 높게 나타났다. Farnensene은 활엽수림과 침·활혼효림에서 5월~9월 사이에 집중적으로 나타났으며 그로 인해 침엽수림보다 NVOCs가 높게 나타났다. 하루 중 NVOCs는 일출, 일몰, 남중 순으로 높았고, 기상인자의 관계에서 온도와 습도에 상관관계를 나타냈으며, 풍속은 상관관계를 나타내지 않았다.

The study was conducted to provide valuable information for forest healing to visitors by analyzing daytime and monthly trend of phytoncide (NVOCs) emission. For this, correlation between climatic factors and the amount of phytoncide emission in three different forest types was analyzed. Phytoncide emission was measured in Saneum recreational forest for one year from the end of May 2016 to middle of May 2017, twice a month at sunrise, culmination and sunset. NVOCs samples were collected at coniferous forest, deciduous forest and mixed forest. The MP-Σ30N and Tenax Ta Tube were used for collecting forest air. The sample data were then analyzed by TDS/GC/MSD method. The climatic factors such as temperature, humidity and wind speed data were obtained from Korea Meteorological Administration. It was found that NVOCs was increased from April and after that slightly decreased but increased again in June, as moving toward September. After reaching peak in September, phytoncide emission was gradually decreased during winter time. The average annual concentration of NVOCs in deciduous forest was 2.548μg/m3, in mixed forest 2.517μg/m3, and in coniferous forest 2.078μg/m3. NVOCs major components such as Farnesene, α-Pinene, Limonene, Myrcene, cymene, Camphene, β-Pinene, Sabinene showed higher values in order. Farnensene has a trend to concentrate in deciduous forests and mixed forests from May to September, which emitted higher NVOCs compared with phytoncide emission in coniferous forests. NVOCs concentration was higher in order at sunrise, culmination, and sunset. This study showed significant correlation between NVOCs and climatic factors such as temperature and humidity, while no correlation was found between NVOCs and wind speed.
