Theoretical researches about the role of fire factor in forming, functioning, stability and dynamics of geosystems are presented. Analysis of common modern scientific concepts in relation to renewal of natural complexes is conducted. A concept «fire relaxation geosystems» and his correlations with other processes of researches after fire influence is considered.
Present results in relation to the consequences of influence of fire factor on an environment require generalization, with the purpose of exposure of conformities to the law of renewal and renewal of geosystems after the consequences of influence caused fires depending on a geographical zonality, landscape structured and individual features of geosystems.
