In the best practices, planning of urban green spaces is managed in such a way that it follows the key principles such as meeting per capita standards and providing accessible and balanced distribution of these spaces all across the city. In the context of emerging economy, these principles are unfortunately not followed strictly all times. In this study, it is attempted to investigate Tabriz city of Iran is in terms of ecological planning to quantitatively analyse its green space characteristics. The used methodology includes determining the relevant urban green space development indicators (e.g. accessibility, per capita supply, balanced distribution, and continuous development of urban green spaces) from the literature and using the secondary data collected from variety of sources to analyse the study area. The study seeks to provide a comprehensive view on status of green spaces in Tabriz in the light of ecological principles and indicators and GIS-based spatial analysis. Results indicate that: a) Green space per capita provision in Tabriz is much lower than the national and international standards (some districts offer only 0-1 sq.m. per capita green space); b) Districts of Tabriz do not have a balanced distribution of green spaces and access to green spaces on foot (only 18% of the population can access green spaces within a 5 minute walk); c) Except for the provided street side green spaces, all other passive or active types of green spaces in Tabriz are not continuously linked (no continuity to form a green corridor or linear greenways). This study also comes up with some recommendations for Tabriz and other cities with similar characteristics.

Rapid urbanization has brought environmentally, socially, and economically great challenges to cities and societies. To build a sustainable city, these challenges need to be faced efficiently and successfully. This paper focuses on the environmental issues and investigates the ecological approaches for planning sustainable cities through a comprehensive review of the relevant literature. The review focuses on several differing aspects of sustainable city formation. The paper provides insights on the interaction between the natural environment and human activities by identifying environmental effects resulting from this interaction; provides an introduction to the concept of sustainable urban development by underlining the important role of ecological planning in achieving sustainable cities; introduces the notion of urban ecosystems by establishing principles for the management of their sustainability; describes urban ecosystem sustainability assessment by introducing a review of current assessment methods, and; offers an outline of indexing urban environmental sustainability. The paper concludes with a summary of the findings.
