Abstract :

Background and Objective: Urban green space has a very important role in the sustainability of the city. Green space per capita is one of the main factors to planning and management of a city. In this study, green space per capita estimation of Khomein city was investigated. Material and Methodology: Satellite imagery was used to measure green space and parks per capita. For this purpose, using Sentinel-2 imagery, land use map was developed in four classes including: Bare lands, habitat, urban parks and farmlands. The urban park layer was extracted and combined to the four district of Khomein city layer. Then, the green space per capita of each area was calculated. Findings: Green space per capita survey using remote sensing approach shows a severe shortage of urban green space in this city, especially zone 3 in the southeast of the city with 1.66 m2 per capita, meanwhile, this zone had the lowest value among all zones. In this city, green space has an inappropriate distribution and the highest green space per capita value was 3.43 in zone 1. Zones 2 and 4 had an average of 3.22 and 3.27 m2, respectively. Discussion and Conclusion: the results show that the green space per capita of the city is very low compared to the standards and requires special attention of decision makers to increase and expand the green space in the city. So in the near future, a comprehensive analysis of the green space and the reasons for this shortage should be addressed.
