Özet

This research assesses Herat City's urban ecological degradation in 2000, 2013, and 2021 using Landsat and MODIS data. A Mean Remote Sensing Ecological Index (MRESI) is developed by integrating Known Granulation Entropy (KGE) and COmprehensive Distance-Based RAnking (COBRA) algorithms. Five ecological elements are considered: humidity, greenness, heat, dryness, and AOD. MRESI declined from 0.4544 to 0.4100, indicating deteriorating urban ecological quality. Spatial degradation increased from six to nine districts. MRSEI identified as the most representative indicator, effectively reflecting the urban ecological quality of Herat city. This approach offers an effective and economical method for managing urban development and spatial control.
