Forest fire plays an important role in determining the species composition, age structure, and ecological processes of forest ecosystems. The high forest fuels accumulation coupled with a warmer and drier climate in recent decades makes the study of potential fire behavior of great practical significance. However, most forest fire behavior studies have been conducted at the plot鄄to鄄stand levels that cannot meet the landscape鄄to鄄regional levels fire management requirements. Researchers and managers are increasingly interested in spatially explicit fire simulation models that can simulate fire spread processes at larger spatial and temporal scales for use in fire management, planning, and scientific analyses. Thus, the main objective of this study was to simulate the potential fire behavior in Fenglin Nature Reserve under the low, moderate and extreme fire danger ratings with a spatially explicit fire behavior simulation model, FARSITE (Fire Area Simulator). According to the fire severity danger standard developed by Rothermel and Rinehart, potential fire behavior zone maps were obtained based on the FARSITE simulation results. Main conclusions from this study were drawn: 1) Under the low fire danger rating, the potential burned areas of classes 砖, 域, 芋 for Fireline intensity were 17765. 82 hm 2 , 105. 5 hm 2 , and 1. 89 hm 2 , respectively. The potential burned areas of classes 砖, 域, and 芋 for Flame length were 17722. 71 hm 2 , 61. 47 hm 2 , and 0. 81 hm 2 , respectively. under the moderate fire danger rating, the potential burned areas of classes 砖, 域, 芋 for Fireline intensity were 16349. 04 hm 2 , 1483. 92 hm 2 , and 6. 75 hm 2 , respectively.
