The key task of megacities` sustainable development is creating a comfortable and safe urban environment. Formation of green zones is one of the priority tasks of the modern strategy for the development of Russian cities. Differentiation of green areas makes it possible to assess the quality of the urban environment. Public city parks and parks of culture and recreation are of the greatest interest in this respect, since these facilities occupy the largest share in the balance of the city's territory.
