In order to solve the management tasks, it is necessary to have a clear
understanding of the structure of CPE whose determining parameters, in particular, are
as follows:
➢
vertical structure which is determined by layers (the layer of dominant trees;
middle layer; the shrub layer; the moss-and-grass layer; the layer of occurrence of
rhizomes and roots of herbaceous plants that take root in the topsoil – 15-20 cm; the
layer of herbaceous plants with a deeper arrangement of roots – 50-70 cm; the layer of
shrub roots – 1-3 m; the layer of roots of tree species (H – up to 5-6 m), forest litter (H
– 1-3 cm); humus horizon (H – 20 cm-1,5 m); eluvial (leached) horizon, or
accumulation (H - 0-20 cm); transitional horizon (H – up to 180 cm;).
➢
horizontal structure: number of rows, width of rows, tree spacing in rows and
strips (coulisse), number of strips etc.
The analysis of the Standards ISO 9001: 2015 and ISO 14001: 2015 has shown
that the requirements for the standardization of the quality of protective plantings
include, in particular, the careful study of not only the external and internal
plantation environment, but also the application of the process approach to assessing
the impact of the main environmental factors on the processes of ecosystem
functioning. In accordance with international commitments, special attention is paid
to the issues of regional and local monitoring of the production process of
biogeocoenotic cover [1]. In general, this concerns the assessment of its
environmental potential and, in particular, the productivity of modern
anthropogenically transformed ecosystems. Such productivity compared with the
corresponding indicators of potential natural complexes can serve as an objective
basis for estimating and forecasting the consequences of anthropogenic changes in
the environment. It is estimated by the indicators of total (gross) primary
productivity (GPP) of a part of the biosphere or the region as a whole and its
individual sections in particular. However, obtaining such indicators even by
satellite monitoring methods is very problematic.
The quality of plantation is assessed by two indicators: viability and protective
efficiency. Effective cultivation of steady-state and long-lived protective forest
plantation depends on the strict implementation of all aspects and consistent carrying
out at a high technical level of all activities necessary for creation and maintenance of
the planting [2].
To compress the various environmental information obtained as a result of
ecosystem monitoring, effective are integral indicators that allow assessing the state
of the biotic and abiotic components of ecosystems and visualize the state of the
Environment in the areas being surveyed [3, 4, 5].
The works [6, 7] substantiate the system of criteria and indicators for assessing
the state of forest ecosystems in urban land. The state of the biotic component of forest
