Abstract
A system of units for detailed zoning is proposed reflecting the action of three factors: tectonic movements, subdivision of the shelf into three vertical belts and geographic zonation. The main initial unit of zoning of the shallow seabed is the underwater landscape. It occurs within one morphostructural county, one vertical belt, one geographical zone. The landscapes of the upper belt of the shelf (coastal zone of the sea) are characterized by the greatest diversity. The internal bionomic heterogeneity of landscapes depends on their morphological structure: a system of horizontal subdivision biotopes - facies, landforms and vertical zones, floors, steps. A fragment of the detailed zoning of the north-eastern Black Sea morphostructural county is given as an example. The accumulation of a database containing information on the detailed zoning of marine ecoregions will make it possible to identify analogue landscapes – bionomic areas with similar characteristics but located in different ecoregions.

Keywords
marine ecoregion, concept of underwater landscape, detailed regionalisation, a case study of the Black Sea.
