Abstract

Earth metrics are usually the broadest and most diverse measurements of space metrics. Many of these metrics have been developed specifically for urban studies, focusing on spatial patterns such as density, sprawl/compression, centrality, land use mix, connectivity, or accessibility. The current research is applied in terms of purpose and in terms of descriptive-analytical method and based on remote sensing data. In this research, firstly, the land use map of 2013 and 2015 was prepared using Landsat satellite images and using ENVI 5.3 software with a supervised classification method in 4 classes of urban space, fields, gardens and man-made wastelands. . which shows the ecological changes of the green space of the study area in a period of 7 years. Then the land use changes of the region were prepared with the help of ArcGIS and finally analyzed using Fragastas software. The findings of the research show that the green space of the city of Soumesara is decreasing and turning into a man-made space, that indiscriminate constructions have had important effects on the ecological structure of the region, as a result of which the green and barren spaces are not used for residential purposes. and the highest rate of conversion of green space use to artificial uses and after that was waste use.
