“Space identity” and this effects on analyzing the patterns of settlements and their space syntax, have opened new horizons in geomorphology and presented cognitive geomorphology to its world. Cognitive geomorphology is the understanding of space identity and its contribution to the meaning of collective biomass patterns of social mechanisms (Valdi, 1400). In cognitive geomorphology, the relationship between natural and human phenomena has become more clear and suggests the necessity of cooperation and cooperation of natural and social researchers. Obviously, what has been understood and obtained in the phenomenological method and space analysis of digital data is significantly different from what is mentioned in classical geomorphology. In cognitive Geomorphology, space identity is of particular importance in understanding the environment. In order to gain recognition and understanding of space identity, we must return to the memory of natural history, space and the logic of space syntax. In this research, by explaining and formulating the pattern of settlement space, in the realm of geomorphological knowledge and based on Gilbert's view, which relies on a kind of Paraphrastic phenomenology, The theory of "cognition" was analyzed and evaluated according to the geomorphic characteristics of the region. Geomorphic evidences, statistics and their role in identifying social mechanisms were investigated. Accordingly, in Yazd basin, the space identity of glaciers and lakes played a significant role in the syntax of urban and rural configurations. That,the logic of space syntax of cities can be considered as a function of the coastline of old Lake Yazd and rural mechanisms in this region as a function of the water and ice equilibrium line during the Quaternary cryogenic period. In the meantime, the technological achievement of the people of this region, with the invention of Qanat in the continuation of the natural Allometry relationship between mountain and the hole of this region despite major environmental changes, can be considered as one of the empirical intelligences of these peoples from the cognition and understanding of the environment.
The present study was conducted by phenomenological method. This method has a trend to advance the research objectives, which includes the following steps:
Step 1: In this stage, based on the theory of "lakes of the fourth era of urban civility bed in Iran", (Ramesht 2001) the pits of Yazd were studied and its lake was proved. Topographic analysis (PO) was performed. Therefore, in this stage, the characteristics of Yazd hole and its relationship with the mountains adjacent to it were determined.
Step 2: At this stage, it was necessary to identify the identity-building parameters in the region based on its historical memory because the existence of this lake raised the question of what mechanism the water of these lakes was directed to this hole by and what characteristics it had.Therefore, first, the separation of Yazd Lake from meybod hole of Ardakan from the hydrologic point of view, then the alometry components were calculated.
Step 3: In this stage, based on Hillier's method, the relationship between glaciers and node points of biological identity was drawn and after achieving the syntx of these points in space, its logic was calculated.
Results and Discussion
In this study, the discovery of space identity and its role in the identification of social crystals in Yazd is the main goal in cognitive geomorphology. The researcher's view and subjective background here have played the main pillar in a new approach to creating social mechanisms in cities and villages of Yazd and also played an important role in presenting the final propositions as a result of the work.
The two space identities of glacier and lake obtained in this study have defined the logic of space syntax of cities and villages of Yazd. The logic of this space syntax was the theory of "hillier space syntax logic", which has been confirmed with the support of the theory of "lakes of the fourth era of urban civility in Iran", "Geoallometry" theory and "space cognition" theory.
The results can be considered as a foundation for fundamental planning studies in Yazd province, which are expressed as several propositions:
1- Yazd-Meybod-Siahkouh pit formed a lake during the Qutterner era. The lake was divided into two lakes of Yazd and Meybod-Siyahkuh due to tectonic factor. Yazd Lake dried up a little later because it benefited from the support of Shirkooh and the building of Yazd city was founded on the lake bed. The meybod-siahkouh derpache was dried earlier in the thermal period and the first social mechanism was built on the terrace of Meybod Lake and the traces of the lake are now seen as desert in Siahkouh.
2- Geoalometry theory in Yazd showed that the ratio of lake surface to ice-making surface was proportional in the past, but today this ratio has disappeared and unbalanced has occurred in this ratio.
3- Glacial space identity and water and ice equilibrium line play an undeniable role in the logic of rural layout. Spatial identity of lake and land and water equilibrium line play an essential role in the logic of urban syntax. These two identities are relics of the memory of the region's past natural history, some of which have been left behind.
4- Biological crystals in the formation of yazd urban network organization and villages reflect their superiority in space identity and with the pattern of urban and rural social mechanisms in identity-building points (water and ice and land equilibrium line). Of course, what happened in the modern era in Yazd has been the disruption of this order in the city.
