Abstract
The author provides information on a developed method of geoinformation mapping hydrobionts in order to automatize digital cartographic images formation with spatial-andtemporal distribution of species and long-term trends of freezing surface waters’quality changes at studying relationships in the functioning of hydrobiological communities. The features of technique with the description of technical stages for creating databases and constituent elements of geoinformation software by the example of designing a regional geoservice with interactive plankton-and-benthos-aquatic-organisms’ maps in the Baikal natural territory are presented. Signs mapping the classes of water pollution by hydrobiological indicators on points available for recognition by colour-blind people are offered to be applied in cartographic material. They are easily reproduced on objects near surface streams in cases of water pollution for warning the population.
