Tóm tắt

Seaports are vital gateways driving Vietnam’s socio-economic development. However, large-scale port expansion and construction have significantly altered land use/land cover (LULC) and affected coastal environments. This study applies multi-temporal remote sensing (Sentinel-2 imagery from 2022–2025) to analyze spatial changes in three key areas: Lach Huyen Port (Hai Phong) – a mega port built on reclaimed land; Lien Chieu Port (Da Nang) – an expanded port; and Can Gio (Ho Chi Minh City) – the proposed site of an international transshipment hub. Using Google Earth Engine (GEE), shoreline positions were extracted. LULC mapping and change detection employed NDWI/MNDWI indices combined with supervised classification. Results show that: Lach Huyen developed more than 1,200 ha of port infrastructure from reclamation, Lien Chieu expanded by about 350 ha, while Can Gio maintained a stable mangrove ecosystem, serving as a baseline dataset for future monitoring. The study highlights remote sensing as an effective tool supporting sustainable planning, management, and environmental monitoring of major seaport areas.
