Introducing and Applying Landscape Ecological Approach in City Scale (Case study: The City of Tehran)

Landscape Ecology is a base for analyzing and managing the landscape by using some key concepts including structure, function and change. This approach is used to conserve the existence of green and open spaces in urban environment and to integrate the urban ecological landscape. In the last decades, uncontrolled growth and landscape structural alterations of Tehran city has caused important structural disturbance in urban and natural landscapes. It has changed the function and has disturbed the ecological balance in Tehran city. In this paper with the aim of improving the current conditions, land cover map based on Landset satellite image (2002) was prepared and urban landscape structure of Tehran was studied in 3 scales (Macro, Middle and Micro). Then, the structure and function relationship and landscape structure was studied. Tehran was divided to some zones and sub zones according to the landscape features and based on that, some strategies were given for restoration the urban landscape structure.
