Introduction
Looking anatomical- functional planning to various aspects of life in the past has caused in the late 1960s. It was influenced by the needs and knowledge of new modern social concepts such as social welfare, quality of life and social justice in the realm of planning and public outreach programs. It is essential to apply development of these concepts in order to achieve quality standards in the utility of urban environmental quality, involving environmental, cultural, social and psychological asspects.

Following the increase in urbanization and high-speed changes in the context of urban studies in Iran, environmental quality in urban areas has declined sharply. Another part of social capital as the relations influenced by factor is focused as a lost chain of urban planning and designs.

Urban spaces are a tool for urban designers to improve and organize the environment and they have the ability to provide the necessary substrates for the formation and promotion of the social capital. In other words, points with higher degree of environmental quality have suitable substrates for the formation of social interactions and will have a higher social capital.

It has the results and observations in the areas under study. It was indicated that there is an inverse relationship between social capital and environmental quality. This means social capital increases in the level of environmental quality is diminished that this field studies and surveys in the neighborhood was confirmed. The rugged interpersonal relationships, communication and trust rates are significantly higher that are redolent linked to social capital. In other words, environment quality is impressible from state organizations more than people that live in garter. That means despite high social capital in the bottom areas, there is not good attention of government and environmental quality are low. These areas are suffering from unlikelihood.Meanwhile uptown neighborhoods with low social capital due to the special attention of organizations had relatively good quality of the environment.
