Ecological Systems and Devices Annotation << Back On influence of negative ecological consequences of forest fires Гришин А.М. Consequences of the action of a mass forest fire on Los Alamos (the USA) in May, 2000 are considered. The determinate-probability model and a formula for estimating probability of initiating mass urban fire as a result of forest fire action are presented. It is stated, that a method for calculating probability criterion of atomic industrial enterprise safety should take into account drastic changes of environment state parameters resulting from forest fires.
