Abstract: Fuel load and water content are important factors affecting surface fire spread in forest fires.This work selected cinnamomumcamphora leaf and pine needle of pinusyunnanensis as the research object,carried out the fire spread experiment under flat slope conditions,with different fuel load and moisture content.It was observed that under the same fuel load condition,the flame length,the rate of spread,the fireline intensity and the radiative heat flux decreased with the increase of water content,while the residence time increased.Under the same moisture content condition,the flame length,the rate of spread,the fireline intensity,the radiative heat flux and the residence time increased with increasing fuel load.

Key words: forest fire, surface fire spread, water content, load, rate of spread, fireline intensity
