Abstract
It would not be far-fetched to say that people’s lives depend on their environment and its quality. With growing urbanization of this dependence is growing increasingly urban environment. Urbanization not only balances economic and social development in the cities but also stirs the regional ecological imbalances and the natural areas. In addition to these problems, there is disruption of water, air, soil and environment built on imbalances between urban areas and the lack of social vitality and frustration. All cities, especially metropolitan with developing economies face to uncertainty in terms of health, environment and quality of life. This article utilizes the ecological and environmental issues and integrates it with urban metabolism approach to the study’s revival of urban ecology, something that results in enhanced quality of life for citizens. This research is the theoretical and analytical method. In the research process of this study, related domestic and foreign literature subsequently of traditional and electronic library resources, books and articles published in journals have been used. According to the type of research in this study, descriptive analysis was performed. Based on findings of this study, urban ecology is a tool to control and guide of urban growth and activities in a way to improve quality of urban environment. Applying urban ecology in designing cities has provided opportunities to create practical ecological systems. By using them, natural process, human activities and urban environment could be combined. Moreover, urban metabolism as an indicator of urban sustainability and a part of urban ecology includes two main related and non-contra-dictory approaches of odum and MFA. Due to difficulties which modern cities face to, benefiting and applying these approaches seem vital.

In this age of ecological attitude, one of the most important issues in the world in sustainable development and land-use planning, especially in a city, is human population growth [1] [2]
Urban environment faces to urban population growth and natural ecosystem replacement
With the growing urban population, large cities are facing numerous problems such as expensive ground that play an important role in the growth of the city, land-use changes and restrictions on the development of green spaces and even replacing them with other kinds of land uses such as residential or commercial inner city and industrial users have been on the fringes of cities
Summary
In this age of ecological attitude, one of the most important issues in the world in sustainable development and land-use planning, especially in a city, is human population growth [1] [2]. With the growing urban population, large cities are facing numerous problems such as expensive ground that play an important role in the growth of the city, land-use changes and restrictions on the development of green spaces and even replacing them with other kinds of land uses such as residential or commercial inner city and industrial users have been on the fringes of cities. While freshwater resources are limited, water shortages are due to political competitions, the technological and financial barriers, and limited access to water leads [5]. It promotes urban agriculture programs, as a part of an integrated approach to water it. All the problems and complexities mentioned in urban ecology cause a sense of the need to consider new solutions such as ecological solutions with the metabolic approach as soon as possible, and with such an approach can reduce the damage to the city
