Abstract

Landscape fragmentation is the most important challenge in urban development. This challenge prevents the flow of materials and energy in the region. These changes affect ecological characteristics. In this regard, ecological networks are considered as tools for conservation planning. Therefore, satellite images were used in the years 2006, 2011 and 2017 to evaluate the ecological networks of Karaj Metropolis. The Classification and preparation of land map conducted based on land cover and with the support vector machine algorithm. Landmarks were also used to assess the status quo and the process of changing heterogeneity, continuity, and communication-isolation networks in previous years. The results showed that the trend of criteria changing in the study area is not desirable. The inappropriate process of changing of Space landscape heterogeneity criteria, the conjunction of the same spots across the land, and the optimal communication reduce the ecological function and the consequence is a decline in the sustainability of ecological networks. Also, due to the decreasing trend of metrics in green spots, especially human green, and the increasing trend of metrics in construction and open spots, in sum, it can be concluded that the ecological function and the ecological network characteristics of the landscape are following a descending trend.
