Abstract: Analysis of island reefs’ land cover evolution plays an important role in the exploitation of island reef, the conservation of marine resources and the development of marine economy. This paper is based on high resolution remote sensing images. With the usage of technologies of remote sensing and GIS (geographic information system), a series of experiments of land cover classification, extraction and change detection were done for Zhaoshu Isle, which belongs to the Xisha Xuande Isles, from 2008 to 2014; eventually Zhaoshu Isle long phase surface coverage status was formed. A classification system of island reefs’ land cover was built as the basis. With the usage of land cover and transfer matrix, along with the consideration of change parameters such as net changes, exchange variation and total amount of changes, an analysis of the land cover variation of Zhaoshu Isle has been performed.

Key words: island reef, land cover, remote sensing, geographic information system (GIS), change analysis
