Statement of the problem: Maintaining the urban ecological network leads to urban sustainability and landscape improvement in cities, which is the main task of landscape planners. However, due to the increase in urbanization and the uncontrolled expansion of construction in cities, the first damage is caused to nature and spaces related to landscape ecology. According to the study, the landscape of District 22 of Tehran is losing green space continuity and reducing ecological continuity with the increase in construction.

Research objective: The aim of this article is to identify the weaknesses of the landscape ecology of District 22 of Tehran and to address them in order to increase the continuity of ecological networks in order to increase physical cohesion and increase social solidarity with the continuity of green space and the extension of nature outside the city into it through solutions such as green belts, the expansion of large green spots, and the use of natural corridors such as rivers, valleys and their extensions.

Research method: The study of landscape metrics in this article was carried out through a four-stage process. Initially, Landsat8 satellite images were used to examine the trends in landscape elements from 2013 to 2020. Then, the Quic Atmospheric model was performed, and in the third stage, the spatial resolution of the images was increased every two years using the panchromatic band and the Gram Schmit command, and finally, the processed images were cropped using the 22-zone boundary. Satellite images were processed using ENVI5.3 remote sensing software.

Conclusion: The most important result of the data analysis is that the number of spots (NP) has increased from 1391 spots to 1687 spots during the years 2013 to 2023, which indicates that the spots are getting smaller and the continuity of the landscape structure is disappearing. However, examining landscape metrics in the vegetation layer, given the constant patch area and percentage of this layer, along with the decrease in the number and density of patches, can show that despite the increase in construction, a successful effort has been made to preserve vegetated lands in recent years.
