Abstract
The distribution of bacteria in separate tiers of the floodplain ecosystem was studied by the methods of direct luminescent microscopy and inoculation onto agar media. The maximum concentration of bacteria was determined in the litter horizon; the bacterial population gradually decreased in the phylloplane and in the soil horizons. The taxonomic structure of the bacterial complexes changed in the vertical direction (in separate tiers) and from season to season. The effect of the floodplain process was seen in the specific composition of bacterial communities in the lower soil horizons; the latter were enriched in the bacterial forms derived from the flood water (spirilla, slipping bacteria, and coryneform bacteria).
