摘要: A key driver of biodiversity loss is human landscape transformation. Change detection and trajectory analysis are frequently applied methods for studying change. We studied to what degree habitat-specific change provide different information on compared the with land-cover statistics. Our research was carried out at two spatial scales (regional, 1800 km2, 360 random points; local, 23 polygon-based maps) in Kiskunsag, Hungary. Spatio-temporal databases were prepared using historical maps, aerial photos satellite images from 1783, 1883, 1954, 2009. Local expert knowledge history recent vegetation used during reconstructions. found large differences both between based analyses. Habitat-specific revealed that grassland not continuous habitats, as implied. Ploughing affected...
