- Аннотация: The paper focuses on the structure of land and bottom natural complexes of the Black Sea coast of the North-Western Caucasus. The landscapes of the Abrau Peninsula with “Utrish” reserve have been chosen as the main objects for this study. Complex of methods including field landscape mapping and profiling, using bathymetric survey and saturation diving, analyses of remote sensing data of high resolution (Landsat, Quickbird) was used during the study. Four main types of the sea coast with different land and submarine structure of natural complexes were revealed – abrasion rock (flysch), abrasion landslide, denudation landslide and accumulative. The most simple spatial structure is typical for the abrasion rock and accumulative coasts which are characterized by offshore with rather monotony relief. The denudation landslide coasts are distinguished by more mosaic and complex structure due to the complexity of relief and bottom deposits. Established regularities prove the hypothesis of morphogenetic interaction between land and bottom natural complexes of the coastal zone that permit us to use the different types of coasts as indicator of the structure of submarine landscapes. It was ascertained that the state of vegetation – ecological forms, height of trees and bushes, their density, amount of bush species and so on – changes as well as biodiversity on some distance from the sea mainly due to the strong winds and marine impulverisation. The detection of alga species from the Red books of Russia and Krasnodarskiy Kray such as Cladostephus spongiosus, Phyllophora crispa, predominance of kelps and oligosaprobic species (Padina pavonica, Codium vermilara) indicate the relatively pure water of the Black Sea within sea area of the “Utrish” reserve. But the increasing of ability and amount of species of green alga in comparison with the middle of the last century prove the fact of eutrophication of the Black Sea water as a result of the intensification of anthropogenic effect.
