| Abstract | The coral reefs and seagrass play an important role in tropical marine ecosystem. The continuous degradation of these habitats in Vietnam is serious issue. This research embodies about this problem in Nui Thanh district of Quang Nam province. Integration of remote sensing and GIS has offered the information of the change of marine environment in Nui Thanh district through mapping the changes of coral reefs and seagrass during 1990-2000 and 2000-2010. In this study, Landsat TM images of 1990, 2000 and Quickbird image 2010 has been used. Band ratio, color composite, principal component analysis (PCA) and water column correction (WCC) techniques were carried out to improve reflectance of benthic. The image classification was executed based on the images after applying water column correction technique. The overall accuracy estimated was at 80.95, 80.95 and 85.71% for maps in 1990, 2000 and 2010 respectively. The change detection techniques are used for changes detection of seagrass and coral reef. The result shows that these areas in Nui Thanh district are decreased during 1990-2000 and 2000-2010 periods. This valuable information will help the local government in assessing, monitoring and making plan for sustainable development of coral reefs and seagrass. |
