| Summary: | 碩士 === 國立臺灣大學 === 森林學研究所 === 92 === This study applied geographical information system and statistical methods to analyze historical wildfire data in the Chiayi Forest District of Taiwan Forestry Bureau from 1950 to 2003. The results revealed characteristics of wildfire such as intended occurring month, potential burning location, fire-favored tree species, frequencies, and burning area. First, annual wildfires start in November, reach to the peak in February, and then decrease to end until May. It not only matches the dry seasons of the research area, but also has a deep implication in which the relationship with the social-economic activities relies on. Second, as discussing the potential burning locations and frequencies, we find that Da-pu Management Unit is the most frequent fire-tendency compartment, which occupy 61.86% frequency of all the wildfires. The reasons lead to its early economic developments and social activities. The estimated burning area is fairly small. Combining the information of social-economic activities in these potential areas, the reason shows the way to the quick notice and extinguishments of wildfire because of a dense population and convenient traffic network.
