Study on the Relation between the Moisture Content of Forest Inflammable Material and Forest Fire Danger

In this paper, regularity on the change of moisture content of forest inflammable materials in relation with forest fire was studied through the measurement of forest moisture content and observation on the forest microclimate. Studies were conducted in 5 types of forest colonies: oak stand, aspen stand, hard broadleaf stand, larch plantation and forest land with mosses. Besides, the data from the local standard weather stations were also used for comparison for variance analysis. Based on the results, possibility and methods for prognosis of forest fire danger by means of meterological data from the local weather stations were discussed.
