Research Progress on Remote Sensing Inversion of Forest Fuel Moisture Content

As the material basis and primary carrier for the occurrence and spread of forest fires, the moisture content of forest fuels is one of the critical factors influencing fire ignition and development. Efficient and accurate simulation of the dynamic changes in forest fuel moisture content is crucial for predicting fire occurrence and behavior. This paper introduces the influencing factors of fuel moisture content, reviews major research methods for forest fuel moisture content domestically and internationally, analyzes existing challenges, and proposes future research directions.
