Plant species used for urban green space in arid and semi-arid regions are not very diverse and many of them are drought sensitive and have high water requirements. This study was conducted to select new species as well as drought tolerant species for planting in green space and afforestation around cities in arid and semi-arid regions such as Tabas. To conduct this research, the required images of Sentinel 2 satellite in the period of 2017, 2018 and 2019 were prepared. Then, by performing the necessary processes, the amount of vegetation was calculated. And finally, maps and diagrams related to each year in the study area in Tabas city, which includes the area under municipal irrigation, Munshi Bashi Children's Park, Women's Park, Golshan and Anonymous Martyrs Garden, Anonymous Martyrs Boulevard and Social Security Boulevard, an area of Imamzadeh Musa Ibn Jafar Kazem and Razavi town were prepared and presented. The final results indicate that in 1996 there was an increase in vegetation, in 1997 with a decrease in vegetation and in 1998 there was a slight increase in vegetation. Also, the amount of water in 1996, 1997 and 1998 was estimated to be 11,250 cubic meters, 1433 cubic meters and 17,200 cubic meters, respectively. The results of the present study give us a worrying result that one of the reasons for these results could be due to improper use of water and improper vegetation in the target areas. In the end, suggestions were made to improve the current situation.
