The method for calculating forest fire behavior index is studied through the practises in DaXing AnLing during 1984 to 1988. It is proved that the method is suited to the forest regions of our country. According to fuel type and four meteorological factors (temperature, relative humidity, wind speed, rainfall), the method can calculate the fire behavior indices of different topography and fuel type condition, such as rate of spread, flame height, fire perimeter, fire area and fire danger class, etc. It is not only suited to single station (small region), but also is suited to more stations (large range). So the method can provide the dependable basis for fire agencies for predicting fire danger and fire behavior and making a decision.
