Forest fire occurrence and spread are closely related to the moisture content of forest fuel. The correlation between moisture content and weather factor is an important, particularly, the moisture content of forest fuel is determined by weather factor in forestland. The study analyzed changes in forest fuel moisture content by broadleaf Quercus dentata leaves and coniferous Pinus densiflora leaves daily from March 1, 2013 to May 15, 2015 during the Korean forest fire danger season in spring(February 1 to May 15) and fall(November 1 to December 15). To analyze the relationship between fuel moisture content and forest weather, we installed a weather-measuring device(HOBO data logger, U12-012) as well as weather factors outside the forest measured by the Chuncheon weather station. As a result, the weather station data during the spring forest fire danger season, for Pinus densiflora, moisture content correlates very well with relative humidity, while for Quercus dentate, moisture content correlates very well with high temperature, relative humidity. During the fall forest fire danger season, the moisture content in both leaf types did not show a significant correlation with the weather. As for the forest weather data, Pinus densiflora moisture content is correlated with high temperature and relative humidity in the spring, while Quercus dentata moisture content is highly correlated with average temperature, high temperature, and relative humidity. In the fall season, Pinus densiflora moisture content has a highly significant correlation with the relative humidity, and Quercus dentata moisture content is highly correlated with the high temperature.
