Landscape ecology considers the structural complex of an urban area as a set of ecosystem networks and evaluates and designs the interrelationship between the city and natural processes and the environment that creates it. Such an approach depends on creating a systemic evaluation of the ecological structure of urban areas.  In this research, the ecological networks of the land landscape in the city of Izeh are evaluated. The present applied research is descriptive-analytical and uses library and field studies to collect data.  To achieve the research objectives, 5 indicators with 17 sub-indicators were extracted. To evaluate the ecological networks of the land landscape in Izeh City, Colonial Competition Algorithm (MST minimum coverage tree) was used in Matlab 2016 Software environment and to spatialize the studied indicators in Izeh City, Tracking Analyst Methodwas used. The Network Analyst Tools process was put in ArcGIS Software environment.  The results show that the most part of the landscape of the study area is made up of spots and the least part of the area is made up of water spots. In 1986, area in Izeh City, 42.44% of the total area was allocated to construction zone while2006, this amount reached 49.27% and in 2018, it reached 59.02%. In 1986, 18.54% of the total area of Izeh City was allocated to green space zone while in 2006, this amount reached 14.63% and in 2018, it reached 13.66%. Furthermore, in 1986, 37.56% of the total area was allocated to open spaces and 1.45%, was allocated to water zone. This is while in 2006, these numbers reached 35.12% and 0.98%, respectively, and in 2018, they reached 26.34% and 0.98%, respectively.

The performance of landscape ecology and its subsequent changes are hierarchically associated with three levels: the construction of patched units of ecological corridors, the construction of corridor units of ecological networks, and the construction of ecological-humanistic landscape configuration.Where Tehran’s landscape is concerned, a lot of changes have happened in the quality of natural resource, and man-made constructions have increased. An important element of Tehran’s landscape in the north is its valuable natural resources in 7 river-valleys of Chitgar, Kan, Farahzad, Darakeh, Maqsoodbaik, Darband, and Darabad that extend from the west to the east, playing an essential role in promoting ecological interactions.The increasing developments of cities, growth in constructions, and environmental pollutions have seriously challenged these important elements of Tehran’s landscape. On the other hand, the principles of landscape ecology regarding the development of urban river-valleys highlight the importance of managing the landscape’s natural resources, and the need to include them in the hierarchical landscape planning. In order to get to the core of this subject and realize the levels of performance appraisals for urban river-valleys, the present study aims to evaluate the three levels of ecological performance for Darakeh River-Valley in Tehran’s landscape configuration by using the analytic network process. Any degradation in the biological and spatial quality of urban river corridors causes the biological and spatial transcendence of urban landscape to come to a stop. Therefore, in leading the sustainability program for river corridors, paying attention to the indicators of construction measurement alone in configuring applications and ecological patches are not enough, but the qualitative indicators for the performance of patches and corridors need to be considered in balancing, stabilizing, and transcending landscape ecological interactions. In this regard, the “SuperDecision” software is used.
