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.
