Abstract: According to reserching the relation of the forest-resource charatistics and forest-fire, a method is put forward for the first time, which the assessment value of the charateristics of each as size factor is determined first and the assessment value of the potential compartment forest-fire danger is synthetically caculated second. Taking forest experiment station of Jilin Forest Institute as base, the potential compartment forest-fire danger grade map and its concert application have been developed.

Key words: Potential compartment forest-fire danger, Forest-resource charteristic, Forest-fire danger grade map
