Abstract:

The dead surface combustibles of artificial coniferous forests in Chengde were focused in this paper. Predicting models between fuel loading and the stand and landform factors, as well as between water ratio of combustibles and weather factors were established with a regression analysis method. The models were effective in calculating fuel loading and water ratio. Fuel loading, water ratio and thickness of combustibles are regarded as the parameters of potential surface fire behavior. Based on a cluster analysis, the potential surface fire behavior of different forest lands was divided into 3 classes: strong, medium, or weak surface fire. The results indicated that most of artificial coniferous forests were in the status of medium surface fire, the risk of surface fire of mixed forests was lower than pure forests, and that of sapling forests and half-mature forests was higher than near-mature forests.

Key words: artificial coniferous forests, fuel loading, water ratio of combustible, potential surface fire behavior
