System determination is related to organization of urban environment as demoecosystem in relationship population Q environment. It takes to interpret ecological factors as priority in formation contemporary urban landscape and recreational environment. Along with production, living, communications recreation acts as a system forming element of demoecosystem. The present work regards landscape and recreational structure as localized in terms of space multilevel system of verdured zones and other open spaces, in which, along with its basic recreational function, all functions to ensure human life are realized. System investigation showed the following: types of residentional areas are sited in function from magnitude of landscape tracts; overlaid natural factors zones of surrounding protective landscapes are takes to differ urban areas in size and in composition. The influence of suburbs in a large city is of equal to the influence of the suburbs in a small and medium-size town or an urban type community. Revitalizing air of amenity forests, fields, meadowy and hydro parks, suburb forests, enriched with oxygen, ozone, phytoncids with moving of warm air to cold in calm contributes to ventilation of urban areas in the evening, refreshment of the air basin, regulation of temperature and moisture regime in densely built up spaces. Increased number of storeys in urban building of a closed, semi-closed and semi-open type creates conditions of limited influence of positive factors of vegetable kingdom upon residential zones. The types of a built-up area are the function of a size of landscape formations. Presence of zones without breeze in terms of recreational factors within the city allows classifying cities without taking into account their population, administrative status and economic trends. This criterion allows to distinguish a large city among populated areas as a type of architectural environment with inaccessible zones of recreational and healing factors. The characters of location, area of green shelter belt of a city determine the first principle for formation of functional and spatial structure of landscape and recreational formations of a city. The principle of hierarchical structure is considerate the landscape and recreational area in hierarchy: landscape and recreational interior space – landscape and recreational environment of architectural objects (a group of buildings) – landscape and recreational environment of planned district (building estate) – landscape and recreational environment of a city. In typology and taxonomy of landscape and recreational areas it is necessary to distinguish levels of hierarchy and function to be considered. Formation of landscape zone system in each level in the hierarchy is performed in correlation – changes in the parameters of one of them to some extent influences the other. The principle of invariant nature (permanence) of the structure characterizes qualitative side of a system of landscape and recreational zones. Different types of objects of landscape architecture of a city in different levels of complexity have the same number of functional parts and permanent relations between them, performing industrial, domestic, communication and priority function of recreation. The principle of integrity – integration of all elements aimed at one objective. The objectives of urban development in most cases are connected with minimizing or maximizing of this or that function, which is regarded as a criterion of optimality or target function. The principle of integrity – integration of all elements with the same objective reflects the qualitative function of a system. Applied to the performance of specific tasks elated to formation of a system of landscape components the above principle is based on the use of the approach of air and phyto therapy as well as aesthetic therapy. Maximum positive effect form each plant is observed in a specific season, which allows to use a technique of differential air and herbal therapy, as well as aesthetic therapy, with the selection of the most effective herbs in each season. Formation of landscape and recreational urban environment is performed in accordance with the laws of development of ecosystems- principles of density, structural hierarchy, invariant nature, integrity which represent the foundation of development of logical and mathematical models
