南投林區林火影響因子之探討

Influencing Factors of Forest Fires in Nantou Forest District

本研究旨在探討南投林區林火發生之原因，係以1992 至2002 年的火災發生記錄為分析基礎，此期間共發生林火165 次，由分析所得之結果得知幾乎大部分（99%）的森林火災皆由人為原因所導致，而其中又以吸煙不慎（36%）所佔的比例為最多。由起火點與道路之關係亦發現大部分的起火點皆與道路有著鄰近的關係，而火災之發生在不同月份間有著明顯的變化，經由濕潤係數和火災頻度之分析結果顯示，此二者間具有顯著性的負相關，本研究所得之結果，將可提供森林火災防救上的參考資訊。 The purpose of this study was to explore the forest fires occurred in Nantou Forest District. According to the fire reports from 1992 to 2002, there were total 165 forest fires occurred in study area. Those fires mainly resulted form man-caused (99%), among which smoking uncareful (36%) was the major factor. We also fined that many fire staring point close near the road. Fire frequency have clearly trend by monthly distribution. After analyzed the wet coefficient and fire frequency, it fined that they have negative significant related. The results will provide basic information for forest fire prevention.
