摘要

本研究主要目的在於推導台灣二葉松林地內枯死之細質燃料濕度模式。試驗在玉山及雪霸國家公園範圍內之國有林區進行，採取台灣二葉松林地表燃料及三組不同樹種之燃料棒，每隔一小時量測其濕度變化。所得資料運用直線迴歸模式進行分析，結果顯示燃料濕度及大氣相對濕度及氣溫最有相關，為最好之預測因子。本研究結果顯示上述之迴歸式可提供台灣二葉松林燃料濕度量衡及預測參考。

The main purpose of the present study was to model the relationship between meteorological factors and fine dead fuel moisture in Taiwan red pine (Pinus taiwanensis) forests. The study was conducted in Shei Pa and Yushan National Parks of Taiwan. Fuel moisture data were collected hourly on the sampled day by direct measurement of Taiwan red pine lifter samples. The linear regression models were selected to construct fuel moisture content equations. The results showed that the best variables to predict fuel moisture at both sites were relative humidity and air temperature.
