The article is devoted to the study of the information balance of the communicative-textual environment of regional media in the context of the construction of local patriotism of the past. Information balance is considered as a parameter of ecological safety of the environment. Local patriotism is understood as the attitude of the subject and the object of patriotism formed in different spheres as a result of social interaction. An integrative approach is used, which provides the possibility of synthesis of achievements of eco- and sociolinguistics, reference to the analysis of linguistic and non-linguistic phenomena, attraction of the results obtained in different spheres of knowledge. The completeness of reflection of event content in the text space of mass media, types of facts reflected in publications, superstructure of the text are investigated. It is shown that characteristics of the information balance determine the impact on the cognitive sphere of the subject of patriotism. The following features of information balance are established: weak differentiation of regional mass media; the small number and irregularity of publications on the past of the region; the prevalence of reports on commemorative practices and, as a consequence, the frequency of special redistribution of content elements between the elements of the superstructure of the text; the limited repertoire of reactualized fragments of the past; the predominant representation of one type of facts. The article describes the negative impact of non-compliance with the principle of balance on the optimality of impact in the discursive construction of local patriotism of the past.
