1. GEOLOGICAL - GEOMORPHOLOGICAL VALUES AND CONSERVATION, THE WORLD'S NATURAL HERITAGE OF HA LONG BAY, QUANG NINH, VIETNAM

Tóm tắt

Ha Long Bay is a World Natural Heritage site of Vietnam, recognized twice by UNESCO in 1994 and 2000 for its outstanding geological and geomorphological values, particularly its unique limestone topography, prominent karst islands, and caves above and below sea level. Currently, some islands and caves have been severely affected by erosion, collapse, and chemical corrosion caused by waves and seawater, which impacts the beauty of this natural heritage. The results presented in this paper provide additional information for managers in support of conservation efforts.
