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.展开更多
