The city of Long Xuyen is currently accelerating its urban planning efforts to create a more environmentally friendly setting.To support this initiative, a study was conducted to analyze the spatial development and changes in the city's urban landscape from 2014 to 2022.Using an object-based classification method, the study examined shifts in the urban spatial structure and variations in land cover over time.The interpretation of remote sensing imagery from 2014 to 2022 revealed that urbanization has moved toward the southwest of the city in recent years, with a 62.67% increase in residential areas and other concrete structures, and a 50.71% decrease in rice fields.The per capita green space increased from 15.59m²/person in 2014 to 25.56 m²/person in 2022, reaching the standards of urban types I and II.There's also evidence of urban heat islands in high-density concrete areas, especially in the city center.
