Peculiarities of detritus profile morphogenesis in insufficiently studied ecosystems of the Okhotsk Sea region

Grouping of detritus profiles based on detailed analysis of the structures of more than 500 sections and using statistical methods was conducted for the first time. A new name, “detritus profile,” which allows one to consider litter itself, as well as peaty and peat formations in the same coordinate system, was suggested. The wide diversity of the detritus profile structure is explained by the specific character of their development in conditions of frost and mountain relief. It was established that humus and humic horizons are invariant and do not correlate with other subhorizons due to their greater age as compared with upper horizons, thus detecting their independence. Interrelation of detritus profile types with forest types and peculiarities of transformation of organic substances was demonstrated.
