Temporal and spatial variations of landscape changes and their driving forces are analyzed in Yancheng coastal wetlands based on topography data in 1976 and remote sensing data in 1987, 1992, 1997, 2002 and 2007.The results show that the area of Yancheng natural coastal wetlands decreased gradually with the massive loss of Aeluropus sinensis, Suaeda glauca communities and great increase of fish ponds and agricultural lands.A landscape index shows Yancheng coastal wetlands are rapidly deteriorating and experiencing landscape fragmentation.Their driving forces are pushed by both human disturbance and physical conditions with policy-oriented activities of all kinds of wetlands development, alien species introduction and coastal erosion/accretion conditions.The existing development model on Yancheng coastal wetlands might be substituted by wise use and scientific management as soon as possible for the aim of biodiversity conservation and ecosystem health.
