Abstract: Observation points were set in 5 different types of forest including Platycladus orientalis forest, Quercus variabilis forest, Cotinus coggygria forest, Acer truncatum forest and Pinus tabulaeformis forest. Living fuel moisture and dead fuel moisture content of forests were measured from December 2008 to September 2009. Fuel moisture was used for establishing prediction model. The result showed that:(1) fuel moisture was significantly correlated with temperature, humidity, wind speed, precipitation and number of continuous drought days; (2) daily fuel moisture curve presents wave shape, with a trough in 13:00-14:00; (3) fuel moisture content is low between January and March but increases dramatically from April to June and reach the maximum of the year from July to September.

Key words: fuel moisture, meteorological factor, multiple regression, Xishan Forest Centre
