In this study, we use Sentinel 2 satellite imagery and GIS technology to evaluate the dynamic of land cover around Tan Rai bauxite mining area, Lam Dong province (Central highland of Vietnam). 02 Sentinel 2 images taken on November 15, 2015 and December 3, 2020 with spatial resolution 10 m (band 2, 3, 4, 8) were used to classify the land cover using object-oriented classification method. The results of land cover classification are used for creating the land cover status maps from 2015, 2020, and then for mapping the land cover change in the period 2015 - 2020. The results obtained showed that there was a significant decrease in forest area, both dense forest and mixed forest, plantation forest. Meanwhile, the area of agricultural land and industrial crop land increased by about 10% in the period 2015 – 2020. The area of Tan Rai aluminum mining project in 2020 also increased to 376.47 hectares, nearly 2 times higher than 2015.
