The geomorphological and topographic landscapes of Yazd (Iran) are considered, the study of which is effective not only for the dispersal or selection of this or that human activity, but also represents one of the effective factors in the formation of physical structures of spatial constructions. It is revealed that the analysis of urbanization can be influenced by the conceptualization of phenomenology, because from this point of view the basis of human settlement development is primarily a spatial identity. According to the theory of «lakes of the 4^th period of urban civilization in Iran», lakes are considered as the components of urbanism in Iran that form the identity. The present study is intended to complement other geomorphological studies in this area by focusing on the Lake Yazd Lake located in the large Yazd-Meybod-Siyahkuh drainage basin. The work is based on a set of archaeological, geomorphological, sedimentological, space and syntax studies as well as on field data. It is shown that there are separate lakes in the Yazd-Meybod-Siyahkuh watershed, one of which is Lake Yazd. It is established that during the glacial period the lakes merged and ended up in the Siahkuh desert. It is concluded that large cities of Yazd province (Yazd, Meybod and Erdekan) owe their urbanism to the spatial identity, namely the existence of these lakes, while the spatial indeterminacy of smaller cities (Islamabad (Farasha), Taft, Hezrabad and Mehriz)) depends on the water-ice equilibrium line.
