We present the concept of «Standard for the comprehensive improvement of embankments, parks, squares, boulevards in Ekaterinburg». It provides for the introduction of an ecological approach in the development of projects for the reconstruction of existing and future green spaces in Ekaterinburg. We have identified 11 landscape-ecological clusters on the territory of Ekaterinburg. The structural elements of clusters are described - the core, the stabilization zone and the central highly urbanized zone. The core of the cluster is formed by natural ecosystems, which are considered as models for the creation of urban green spaces. Information about the method for calculating the size of the stabilization zone is given. It is proposed to create a special functional zone of natural diversity in parks, squares, boulevards and embankments located within its boundaries. We noted the need to design ecological corridors between scattered green spaces of the city. In our opinion, the presented concept reflects the importance of biological diversity in the urban environment, is aimed at its conservation and restoration, and also contributes to the formation of an identical image of the urban environment of Ekaterinburg.
