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.

Up to now, many different processes for landscape design such as Booth process (1983) have been introduced by landscape experts to aim a landscape project. The Booth process contains an orientation of actions in a landscape design project varying from project acceptance to presentation of constructed plan. The three adjusted sub-parts of Booth's landscape process stages which have been adjusted in a flowchart by the author of this article will be study in details. The aim of presenting such a flowchart is introducing and showing the interdisciplinary relationship between "landscape" and "surveying" experts in executing a design process. These three sub-parts contain some executing actions which are extracted from surveying which introduce this knowledge application in landscape design. These sub-parts contain "land surface features surveying and topographic map providing", "land technical design" and "setting out the design on the land". At the end, there are some suggestions for using new surveying instruments like GPS receivers in order to provide the topographic map in UTM coordinate system and transferring these landscape designs to this coordinate system.
