To the environmental functions of urban green
parks, further factors should be added such as those
of acoustic isolation since some gardens work as an acoustic screen between traffic roads and residential
areas. Plants have individual and collective aesthetic
value, playing an important role in the conservation
of a pleasant landscape, being sometimes the link
between residential urban areas and industrial areas.
City parks and gardens are also the setting for many
recreational activities (children’s play areas, walking,
jogging, etc.). All these services offered by urban
green areas explain the influence of environmental
variables on the prices of dwellings
