Plants as the life giving entities have important role in mental and physical health of human. In the modern time with expansion of the cities and increase of industrial centers and living style change and decrease of social negligence about green spaces as the factor for mental diseases, altogether have been propounded for many psychologists and physicians. In this way considering green spaces is necessary to peace of mind. This article intends to study sense and visual capabilities of artificial green spaces using descriptive method and their effects on human. The results show that connection with green space directly or using senses can contribute to reach mental health. It is hoped this research can provide conditions to further researches.

The uncontrolled growth of tall buildings in contemporary cities has caused numerous visual and psychological issues for urban citizens. This study's framework examined the combined effect of architectural and vegetation variations on the scape of tall buildings and the oppression imposed on citizens. The architectural changes of the tall building included form (rectangular, stepped and pyramidal), gap (in single building (without gap, small and large gap) and between buildings (middle, sides and middle and sides)), console (1, 2, 2,5, 3, 3.5 and 4 m), and setback (1, 2 and 3 m) of the building from the base. Vegetation changes also included the distribution of different tree species on the façade and the positioning of the trees within each species. To assess the impact of architectural and vegetation changes on oppression, the method was based on the framework for assessing the oppressiveness of tall buildings and people's opinions. In conclusion, vegetation demonstrated a significantly greater reduction in perceived oppression compared to architectural modifications. The results of examining the architectural scenarios showed that as the pyramidal form of the building increased and the gap between the single tall building (or between tall buildings) widened, citizen-imposed oppression decreased. Also, as the console of a tall building decreased to less than 2.5 m and the setback increased to more than 2 m, the oppression decreased significantly. Also, the results showed that using concentrated and horizontal vegetation at the base and shaft of tall buildings has effectively reduced oppression (Compared to other vegetation change scenarios).
