Abstract:: Based on the Landsat TM images, changes of landscape pattern of Guilin City from 1986 to 2006 were studied by using “3S” techniques. The results showed as follows: the woodland, construction land and bare land increased, while the farmland, grassland and water body decreased in Guilin City over the past 20 years. The change of construction land was the fastest, most intensive and frequent among all landscape types. At the level of landscape, the number of patches(NP), aggregation index(AI), Shannon’s diversity index(SHDI) and Shannon’s evenness index(SHEI) increased, while mean patch area (AREA_MN), edge density(ED), fractal dimension area-weighted mean (FRAC_AM) and patch cohesion index(COHESION) decreased in this area. At the level of landscape type, fragmentation of the woodland reduced and natural features were strengthened; fragmentation of farmland increased and tended to be separately managed; fragmentation of construction land increased and had a trend of obvious centralization; fragmentation and complexity of water body both increased; and the change of grassland was intensive. The implementation of the policy of the conversion of farmland into forestland, the planting of fruit, the rapid development of rural tourism, urban sprawl and agricultural activities were the main driving factors of the dynamic changes of landscape pattern in Guilin City.
