This study examined the data extracted from the multi-band satellite remote sensing images of Lianbo Beach during four phases of 1990, 1995, 2000 and 2005. The analysis employed a series of spatial landscape pattern indices such as patch density, length of patch edge, landscape diversity index, species dominance, landscape fragmentation index, and the mean fractal dimension index to systematically scrutinize the spatial alteration patterns of the wetland landscape at Lianbo Beach since 1990. The results include:(1) The changes in patch areas from 1990 to 2005 exhibit the increase in grassland, farmland and woodland but the decrease in water bodies and beaches;(2) The intensive anthropogenic activities correspond to the enlarged landscape heterogeneity as demonstrated by the increase of wetland landscape diversity index of 0.9947-1.1247 between 1990 and 2005;(3) The increase of patch numbers, patch density and the length of patch edge, all indicate the enhanced degree of fragmentation in this region. The major natural factor for wetland degradation at Lianbo Beach is the significant reduction of runoffs along the Fenhe River and the Yellow River due to long-lasting drought. Additionally the population pressure serves as the ultimate cause for wetland degradation.
