Space identity and its role in the formation of urban civility in Yazd

Geomorphic and topographic landscapes are not only effective in dispersion or selection of human activities, but also one of the effective factors in the formation of physical structures of space structures. Analysis of urbanization can be influenced by the conceptualization of phenomenology, because in this view, the basis for the development of a human settlement is first of space identity. According to the theory of "4th-era lakes, the crystallization and expansion of civilization in Iran", lakes have been considered as identity-making components of urbanism in Iran. Therefore, the present study seeks to supplement other geomorphologic studies in this field by focusing on Yazd basin, located in the great catchment area of Yazd-Meybod-Siahkooh. This research has been carried out with a phenomenological view based on a set of archaeological, geomorphologic, sedimentological, Space syntax analysis and field visits. The findings indicate that: 1-There are separate lakes in Yazd-Meybod-Siahkooh catchment area, of which Yazd Lake is one. During the glacial periods, the lakes were connected and ended up in the Siahkooh desert. 2- Yazd, (Meybod and Ardakan) owes its urbanism to its space identity, namely the existence of these lakes. 3- Small cities such as Islamabad (Farasha), Taft, Khezrabad and Mehriz take their space identity from the Water-Ice equilibrium line.
