Abstract

The developed set of methods, including ecological, mathematical and statistical methods, reflects the qualitative characteristics of the ground organic horizon in the fields of climatic and biological factors and allows modeling ecological niches of soil-phytocenotic ecosystems.

For the first time introduced the concept of “ecological niche of a soil organogenic horizon”. The volume and thickness of ecological niches of a ground organic horizon are determined. In geography and geochemistry there are examples of the use of such terms — the term “landscape”, which is quite successfully used as a geographic landscape, geochemical landscape and elementary landscape, without causing anyone to doubt the rights use. An important argument in favor of using this interpretation of the ecological niche is the fact that terrestrial forms of detritus are biogenic bodies of nature, which emphasizes their proximity to living organisms within the framework of V. I. Vernadsky's concept. It is no accident that one of the largest researchers, M. Striganova, emphasized the functional unity of living organisms and plant material in modern detritus.

Keywords

ecosystem, the ground layer of organic horizons, litter, typing ecosystems, ecological niches, soil and climatic factors.
