Assessment of some marine ecosystems using sustainable utilization indicators in Hai Phong—Quang Ninh coastal area, Vietnam
Bibliographic record
Abstract
This study is aimed at analyzing key indicators for the evaluation of changes and tendencies of sustainable utilization and management in some marine ecosystems in the coastal waters of Hai Phong - Quang Ninh area. To complete this study, the methods employed consisted of the application of remote sensing data and geographic information systems to extract information on spatial distribution of mangrove and tidal flat ecosystems, as well as on the reclamation area for human development and indicator investigation and analysis, using remote sensing extracted and field survey monitored data with Microsoft Excel (MS Excel). Applying indicators for sustainable utilization and management of marine ecosystems, developed in recent studies for the Hai Phong - Quang Ninh area, demonstrated changes and trends in significant ecosystems, such as coral reefs and mangroves. The outcomes showed that from 1998 to 2003, living coral cover was reduced by 20% on average in the Ha Long Bay area and by 13% in Cat Ba (Hang Trai - Dau Be), and projected that living coral cover would be reduced by a further 10% to 50% by 2010. The number of coral species was much reduced by 15% to 72% in the Ha Long—Cat Ba area. Mangrove area also decreased between 1995 and 2004, particularly after 2000, and is projected to be only 10,000 ha in 2010 in Quang Ninh. Marine ecosystems in the coastal waters of Hai Phong - Quang Ninh area have degraded significantly, particularly coral reefs, mangroves and tidal flats.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
