Development of a Prediction Model for NVOC Concentration with Changing Microclimate in Camellia Japonica Temple Forest

Abstract

This study aimed to make an efficient estimation of the concentration of NVOC with changing climate conditions in the forests possessed by Buddhist temple for the purpose of landscape preservation and procurement of material and operating expenses for Buddhist temple in Korea. To complement economic and technical issues of existing NVOC measurement techniques, the study conducted a total of 48 survey and analysis sessions from May 2016 to June 2016 in Camellia japonica forest, representing the climate of warm temperate zone. The comparison of the NVOC construction in Camellia japonica forest in summer showed 51% of α-pinene (1.79 μg/m 3 ), followed by 19% of β-pinene (0.68 μg/m 3 ). The analysis of daily NVOC concentration showed that it was the highest during the sunrise and the concentration increased when the photo-environment changed and when there was a smaller effect of wind velocity. The study also presented a concentration prediction model with varying microclimate conditions using a multiple regression analysis. The regression analysis on the estimated concentration and the observed data demonstrated that the proposed model had a higher explanatory force at 84.5%. This study offered scientific evidence which can inform the management of 'Buddhist temple forests' along with forest environment in general, helping to promote public welfare and meditation space.
