On the basis of remote sensing and GIS techniques, the Landsat data obtained in 1978, 1987 and 2000 were used to examine coastline changes in the Abandoned Yellow River (AYR) Delta in China. The coastal land lost and gained illustrations were derived from the extracted coastlines, the rates of coastal change were estimated, and the coastal parts that experienced the biggest changes were identified. The results illustrated that the erosion rates of the AYR Delta coast decreased during 1978-2000 while the erosion effect remained strong. The spatial-temporal changing patterns of the northern, central and southern coastal parts in the study area were characterised by slow erosion, erosion and dynamic balance of erosion/accretion.
