Remote sensing monitoring and geomorphologic change analysis of coral reefs are great practical significance for the ecological protection sustainable development reef area resources. A WBMD scheme is proposed to better extract information from island environments Xisha, China. Satellite imagery, after preprocessing, subjected water depth correction mitigate influence on reflectance. maximum likelihood classification model then used geomorphological classification, followed by refinement through a decision tree model, forming scheme. The overall accuracy Xisha Chau Zhaoshu Island based was 97.07% 95.07%. Using this analyze geomorphology 2014 2018 reveals that degradation mainly distributed in lagoon slope around lagoon, has been shrinking year year, while gray sand increased, areas other types exhibit fluctuating changes. Previous studies have indicated area, where significant also observed, raising an alarm conservation efforts
