خلاصة:
The qualitative study of the urbanization process indicates that inappropriate development has caused a great deal of damage to the urban landscape structure. The problem solving tool is planning the ecological networks as matter and energy pathways. Planning natural elements of the structure, including green and open spots and corridors, will guide the researcher toward achieving research goals such as the conservation and restoration of natural resources and the improvement of cybernetic forces to enhance performance sustainability, structural equilibrium, and habitat variability. The methodological model of research in the Karaj metropolis identified flexible elements to strengthen ecological processes. Then, adopting the ecological-sociological approach and forming the urban habitat network, it was applied for sustainability. GIS software was used to map and digitize the data, RS to capture satellite images, and FRAGSTATE 4.2 to analyze the metrics changes in the years 2008 and 2018. The results of Bayer spot changes were -7.98% for CA, +5.79% for NP, and -1.5% for Cohesion, while residential spot changes were -24.15% for CA, +26.16% for NP, -3.96% for Cohesion, and green-space spot changes were -38.8% for CA, +275.5% for NP increase, and -34.0% for Cohesion. These indicated increased discontinuity, decreased natural bedding connectivity, and decreased ecological performance along with its adverse effect on social structure. Thus, using a nature-based planning, we can witness the network dynamics of natural/man-made communication/isolation networks over time, and by establishing a holistic, bio-ethical culture, we can overcome social vacuum. This way, Karaj can move in the excellent sustainable development path.

Therefore, it is possible to first witness the dynamism of the connection-isolation network of natural and man-made elements of the urban landscape over time through nature-oriented planning, and then overcome the social gap by creating a holistic culture based on bioethics so that Karaj city can be placed on the path of transcendent sustainable development.
Meanwhile, considering the increasing population of Iran over the past forty years and the growing tendency to migrate from villages to cities or from counties to the capital, the urban landscape of Karaj is in conflict with the principles of sustainable development; As damage to the natural part of ecological structures can be observed in the form of reduced biodiversity of plant and animal communities and increased disruption of integrated open, water, and green mosaics.
Based on what has been said, considering the goals of sustainable development, including “creating inclusive, safe, resilient, and sustainable cities and towns” and “conserving, restoring, and promoting sustainable use of terrestrial ecosystems, sustainable forest management, combating desertification, and halting and reversing land degradation and biodiversity loss” at the international level, on the one hand, and explaining the problems in this research on the other hand, the issue is presented as the development of an ecological-social gap, for the solution of which we need a holistic knowledge-based tool.
Ecological solution: The large greenway network of Karaj urban landscape - a human-made urban habitat, based on Table 1 (Author) (Refer to the image on the page) Conclusion From an ecological perspective, based on the theoretical foundations presented, ecology chooses more sustainable changes and developments by studying them.
