Abstract: | Geographic information system (GIS), remote sensing (RS), gradient analysis, and landscape pattern metrics were coupled to
quantitatively characterize the spatiotemporal change of land use and landscape pattern over the period 1988–2007 in a coastal
gulf region, southeast China. The results obtained show an increase in cropland, buildup land, and aquiculture area and decrease
in orchard, woodland, and beach area during 1988–2007. Landscape fragmented processes were strengthened and landscape pattern
structure became more complicated in the last two decades in Luoyuan gulf region. The dynamics intensity of landscape pattern
is stronger during 2002–2007 than that during 1988–2002. Spatial difference of urban–rural landscape pattern can be detected
distinctively in two transects in terms of landscape metrics. Urbanization processes and the policy developed to transfer
seawater into buildup land are two driving forces leading to the spatiotemporal change of landscape pattern in Luoyuan gulf
region in the last two decades. |
