ECOLOGICAL-GEOGRAPHIC CHARACTERISTICS OF NATURAL CENTERS OF PLAGUE (USE OF THE DATA-BANK OF EPIZOOTOLOGICAL INSPECTION)

For studying certain ecological-geographic questions connected with th e confinement of natural centers of plague to various elements of the landscape environment, the author used the information-retrieval syste m (IRS) of the data bank for unified reporting of epizootological terr itorial inspections. The structure of the IRS makes it possible to com bine various cartographic material, with different content, with the d ata bank. Investigations conducted according to this principle, using medium-scale maps, showed that confinement of plague epizooties is not iceably expressed as applied to certain elements of the relief within geobotanical complexes of the hydromorphic type.
