| Abstract: | Based on the three TM/ ETM ＋ images respectively in 1989,2001 and 2010 years, using remote sensing and GIS geographic information technology, extracting the land use information, and then analysis the land use information and landscape pattern. The result shows that （1） the greatest change is the bare land and woodland, the largest dynamic change is bare land, the most frequently of land type conversion is the arable land and construction land; （2） the degree of Nan＇ao island landscape fragmentation and the irregular patch shape are increasing. Through the study of land use change and landscape pattern, in order to provide the scientific according to the sustainable development and other ecological environment protection of other uninhabited islands land resources utilization. |
