Abstract

This study investigates the application of landscape ecology in planning and design of urban ecological systems. The ecological approach to landscape planning and the concepts of designing and implementing ecological systems have gained increasing attention in the last two decades. However, the ecological systems of urban environment need more research to consider built and natural patches and corridors together and to provide proper and applicable strategies that meet all of the diverse aspects of planning and designing sustainable urban systems. This approach could help in defining sustainable landscape development, aiming for a balance between both physical and natural systems in urban areas. This research is focused on Tehran’s metropolitan area as a case study to provide a relationship between landscape ecology and urban planning and design to propose a model for analyzing and providing strategies and policies for conserving and resorting urban ecological systems. The spatial structure of green and natural areas are studied and categorized based on the patch-corridor-matrix model. Overlaying the selected layers helped provide strategies for conservation and reclamation, and policies to improve the structure and function of urban landscapes. The strategies to restore the ecological structure and to develop its functionin Tehran metropolitan area are based on structural congruence, aggregate with outliers, local compensation and indispensable patterns.
