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.
