Abstract

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.
