The main purpose of the article was to update the fundamental component in the creation of phytocenoses with controlled properties in the feasibility of ensuring the stability of the structure, composition and condition of such communities. This direction plays an important role in ecological and economic activity, in modern nature management. The key aspects of the management of artificial phytocenoses which form the functional core of cultural ecosystems and landscapes are presented. Crop production, as well as botany and plant ecology as its overall fundamental basis, should implement the goals of strategic and territorial planning in this key. Designing and monitoring the efficiency of phytocenoses of the corresponding economic groups allows ensuring the productivity and sustainability of ecosystems and landscapes. In this case biology, ecology and geography of plants make it possible to determine the fundamental mechanisms of management of artificial biosystems in the corresponding territories. Ensuring a labile balance between potential and real opportunities in biological productivity and environmental sustainability of artificial plant communities is the scientific basis of ecological and economic activity. Phytocenoses of landscaping purposes have significant scientific and practical interest: decorative, protective, environmental, planning. Due to the fact that the phytocenoses of landscaping structures are initially mainly artificial biotic formations, the ecological, landscape-stabilizing and economic characteristics of the ecosystems of cities and villages, first of all, depend on the species and varietal composition of the plants used. Also, these biotic communities strongly depend on the possibility of realizing the biological potential of these plants in such non-specific environmental conditions.
