文章以黑龙江省庆安县曙光林场典型林分为研究对象,通过野外地表凋落物含水率的连续观测,分析了地表凋落物含水率动态变化.利用曙光林场春秋两季的气象数据计算出加拿大火险气候指数系统(FWI)的湿度码,用含水率数据与气象要素和FWI湿度码分别进行回归,得到两类含水率回归模型,旨在为庆安地区森林火险预测预报提供科学参考.
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.
