Diagnostics of the state of urban ecosystems requires the use of integrated assessment methods. Examples
of such urban areas with ongoing degradation processes are almost all major cities. Therefore, the
development of methods for combating degradation processes under different conditions, methods of
reclamation of such lands, as well as organization of monitoring of ecosystem functioning, requires great
attention.
The purpose of our research was to study the features of the structure and dynamics of the emerging pine
forests during phytomelioration on the sand of the Tersky coast of the White Sea and to identify the
ecological and geographical preconditions for phytomelioration of urban areas in different climatic
conditions.
For the first time for the region, the study of the features of the formation of plant communities in phytomelioration over a 20-year period was carried out and the role of plantation structure in the dynamics of
the basic morphometric, biogeochemical, phytocenotic parameters of the forest-forming culture was
revealed.
The role of geoecological conditions in the formation of the structure of pine communities in
phytomelioration was revealed in the study area. Changes in the species and ecobiomorphic composition
of plant communities, in the photosynthetic apparatus of pine, in the content of elements of mineral
nutrition in needles, depending on the age and structure of plantations, as well as the morphometric
parameters of pine growth over a 20-year period are studied.
The conducted researches allowed to study adaptive possibilities of phytomeliorants to various growth
conditions and to reveal the regularities of formation of plant communities during phytomelioration. The
introduction into practice of the results of studies of ecological and geographic prerequisites for
phytomelioration will improve the efficiency of recultivation of urban landscapes in different cities with
different natural conditions.
