- W2938073212 abstract "Urban population growth and physical expansion have caused green spots destruction Consequently, the major habitats of animals in terms of shape, size and spatial distribution are affected and in many cases entirely destroyed. Urban landscape as a result of such a process has often fragmented and scattered green patches. Therefore cities need to pay special attention to restoration of nature. The aim of this study is assessing spatial distribution and improving urban green space network connectivity by using graph theory and landscape ecology principles in Ardabil city. In this regard, by using Landsat satellite images three time span 1987, 2000 and 2014 Ardebil land-cover maps extracted and classified in four classes including ; built-up area, water body, barren land and green zone. Because one of the main principles of landscape ecology is investigating land-use/cover changes, thus land-use/cover changes was detected and compared in three different years. Result shows a significant reduction in green space and reached from 53/37 percent in 1987 to 83/8 percent in 2014. After identifying the changes, by using other landscape ecology metrics, including ; CA, PLAND, NP, ED, MPS and MSI Ardabil city landscape was analyzed. The results indicate that unlike built-up area, green spots in Ardabil city have extremely changed in terms of number, area, size and shape. Therefore the structure of urban green space were extremely fragmented. In the following to develop and improve connectivity of urban green patches, graph theory along with least cost algorithm were used and optimized in Ardabil city were presented.Keywords: Green space, Landscape ecology, Graph theory, Ardabil city" @default.
