Research Review on Change Mechanism and Impact Factors of Forest Surface Fuel Moisture
Forest fuels are the material foundation and the first condition of forest fire occurrence. Forest fuel moisture, as one of the important characteristics of combustible material, is an important factor of forecasting forest fire danger as well as the direct factor in deciding whether forest fires could occur. Therefore, accurate determination of forest fuel moisture content has important practical significance for carrying out the work of forest fire forecasting. This paper describes the moisture change mechanism of the live combustible and dead fuel in the forest, and the factors impacting forest fuel moisture such as temperature, relative humidity, wind, precipitation , solar radiation and topography, which provides important basis for further prediction of fuel moisture as well as the building up of the database.
