Prediction Study on Moisture Content of Litterfall in the Qing'an Area
This paper takes the typical forest compartment of Shuguang Forest Farm in Qing'an County,Heilongjiang Province,as the research object.Through continuous observation of the moisture content in the surface litterfall,the dynamics of the moisture content of the litterfall are analyzed.The meteorological data from spring and autumn at Shuguang Forest Farm are used to calculate the Drought Code of the Canadian Forest Fire Weather Index(FWI)system.Regression models for two types of moisture content are obtained by regressing the moisture content data with meteorological elements and the FWI Drought Code,aiming to provide a scientific reference for forest fire risk prediction and forecasting in the Qing'an area.
