摘要

Landsat TM/ETM+ and Alos remote sensing data of the study area in 1991, 2001 and 2010 were interpreted by using object-oriented RS image extraction technology, landscape ecology theories were applied as well as GIS and FRAGSTATS4.1 to choose reasonable landscape indexes for studying temporal-spatial changes of suburban landscape layouts of Haikou City, exploring spatial features and change tendency of rural landscapes. According to the results, tropical garden landscapes have taken a dominant status in the last 2 decades; tropical farmland landscapes have had the most complicate shapes; tropical open forest landscapes have been most influenced by human interventions but had the best connectivity and high degree of concentration; tropical settlement landscapes and tropical meadow landscapes have been widely scattered with poor connectivity; landscape connectivity has been well maintained; contagion index has changed slightly, landscape equilibrium has been stable; landscape diversity has been maintained, all landscape types have been evenly distributed, landscape fragmentation has increased, and landscape heterogeneity has grown.
