Analysing the Effects of Environmental Recognition on Enhancing the Hidden Natural Landscape of Tajrish River-Valley and its Sociability

The texture of the cities are impacted by forces like natural,economic ,forces of power, social forces and civic institutions. Reflection of Shemiranatgrowth in comparison to the population and economic growth of Tehran and increasing demand for the fine land and weather become directed to Shemiranatarea, especially to its central area, Tajrish; Above factorsand pilgrimage were shaped under the influence of Shemiranatnatural factors. But nowadays extent of the traces of mentioned factors on the natural history of Tajrishhas led to the extinction of environment and emergence of lost spaces. This paper aims to reach for a number of factors to evaluate the sociability of Tajrishriver-valley and the will to collective activities by the course of emergence and role of environmental perception and to ultimately check the feasibility of revival for the natural substrate of Tajrishriver-valley. The subjective picture of users from the environment of river-valley and the possibility of environmental perception in the skeletal space is an independent factor which is impactful on the sociability of the substrate of river-valley as a dependent factor. To have an evaluation over the subject, the skeletal locality of the river-valleys substrate is considered as a part of collective-behavioral locality of Tajrishsquare. the research has been scrutinized on its main framework and the impacting factors on the formation of the natural subjective landscape are analyzed in the skeletal substrate. results show that the existing river-valley in Tajrishsquare can turn into a sociable substrate by taking influences from “comparative-interactive perception” of nature in the subjective image of the users of the space as a part of the green infrastructure.Also subjective landscape of Tajrishis more impactful on the re-design process rather than the objective landscape due to the transfer of subjective image of the space.
