Study of the adaptive opportunities of phytomeliorants to various conditions of urban environmental development Glukhova E.V. Russia, E-mail: [email protected] Keywords. Reclamation, urban landscapes, vegetation restoration, afforestation. 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.
