This study explore fluctuations of land use in Diêm Hộ estuary and Trà Lư estuary area from 1994 to 2013 using remotely sensed data, comparing and verifying with real observation result and some existing maps, especially land use map. The results show that the agricultural land sharply went down, almost 10 million m2 from 1994 to 2001, and above 40 million m2 from 2001 to 2013. There was a significant rise in the area of aquaculture, just below 10 million m2 from 1994 to 2001 and around 22 million m2 from 2001 to 2013. Salt marsh area reduced more than 400000 m2 from 1994 to 2001, continue fell about 300000 m2 to 2013 and distributed more and more scattered. Particularly, mangrove land grew above 10 million m2 from 1994 to 2001, but dropped over 2 million m2 from 2001 to 2013.
