Abstract :

Background and Objective: The rapid development of cities has caused the unsustainability of the human urban environment and consequently fragmented the ecology of the urban landscape. Today, there is a need for a new conceptualization with which to approach ecological diversity, such as environmental planning and design for integrating the urban landscape ecology. The development of urban green networks is one of the essential factors to protect biodiversity and effectively prevent the isolation of populations and species. The purpose of this article is to connect ecological networks in the urban landscape and finally increase connectivity and provide ecosystem services in cities and presenting proposed potential corridors and their scenarios.Material and Methodology: We produced the proposed scenarios by using the improved Gravity model and network analysis in GIS software.Findings: We achieved the prioritize corridors in the northeast area of Tehran by using the cost layer, the impedance layer, and the core patches. In the final stage, three scenarios were developed in the studied area using corridor network analysis.Discussion and Conclusion: Based on the impedance layer, core patches, and cost layer, the functional prioritization of the proposed corridors was discussed to develop and analyze the proposed corridors. This map leads to decision-making strategies and achieving the integration of the ecological networks in the urban landscape. The output of this paper can be used as a basic map for the development and revitalization of urban ecological landscape structures.
