This article attempts to analyze the possibilities of using the semantic language of modern ecological design in urban planning and architectural landscape projects based on a pair of semiotic signs “scale and image”. Their new interpretation for urban planning purposes is due to the rapid development of environmental technologies in urban planning, global climate change, urban densification associated with urban growth and population migration. Therefore, in projects with approaches in the engineering preparation of urban areas, they are interconnected with the surface collection, distribution and purification of rainwater, and at the same time, the use of macro-structures and macro-geoplastics sets a scientific search and a vector of development to create a memorable design of the urban environment through large-scale and figurative elements. Both directions create prospects and opportunities for the development of nature in the city on the basis of technologies that simulate natural processes, when the topic of “semantic images” acquires a new architectural and landscape meaning. In this regard, structures made of artificial relief can be made of different materials and can serve as protection from noise, wind and dust. This article presents options for such solutions.
