SUMMARY
Today, based on high volume of urban constructions, many problems were created including population increase, non-purposeful physical development of cities and increase of environmental population. The development of green space in cities can play important role in environmental balance and adjustment of air pollution. Urban green space is one of the urban uses as its distribution is of great importance in city. The present study is regarding the development of green space in improvement of city quality and its importance in urban life. This study is applied in terms of purpose and descriptive-analytic in terms of method and the required data is collected via document-library investigation and field studies. Using small green space can play important role in improving quality of city view and legibility of urban environment and it has direct impact on perception of citizens and it causes that potential data of urban environment is actualized. The results of study showed that the closer the space to the nature, green space is used in city view and it can take a step toward environment quality improvement. The development of green space beside Milad Hospital (Chamran-Tehran Autobahn) is one of the most effective methods on improving urban landscape quality and it is considered as an ecological display of creating a central green core and connection with Goftego Park as the natural breathing center of city and a tourism center based on location of Milad tower. The development of green space is a solution to reduce air pollution and its impact on people and improvement of quality of cities. The development of green space beside Milad hospital (Chamran-Tehran Autobahn) shows that these spaces besides the increase of fair distribution of public green spaces can help urban environment marking and it improves the quality of life of citizens.
