Abstract:
Forest fire is a kind of disaster, which often damages the ecosystem on the earth. Based on the relationship between forest fire and weather conditions,many kinds of forest fire danger weather indexes are developed to estimate and predict the possibility of ignition, fire intensity and spread,as well as the difficulty of wildfires control.Through reviewing and summarizing various study results,it can be included that the methods for calculating forest fire danger weather index conclude mainly three kinds,i.e.index verification check method,synthesis index method,and statistic regression method.In light of the theory and the applied effect,any method has its own strong point and defect comparing with others,so when it were used in China,the real calculation method should be modified and improved ac-cording to local climatic and environmental characteristics everywhere.
