Abstract: Coastal plain of south Hangzhouwan Bay, central area of the golden economic city triangle made up of Shanghai, Hangzhou and Ningbo, is one of the most developed zones in coastal area in China. The study of its land use and cover pattern dynamics have great significance in the utilization of land resources and sustainable development. In this study, we analyzed the land use and cover pattern dynamics through the interpretation of TM images in 1987 and 2000. The results showed that the areas of land for building, water area and fishery land increased. Paddy field, dry agricultural land, tidal flat, forest land and saltern decreased. Because of the influence of nature conditions and anthropic activities, mean area of patches decreased from 0.245 km2 to 0.173 km2 while density of patches increased from 4.081 pieces/km2 to 5.781 pieces/km2. At the same time, the gross patch numbers had 42% increased compared with that in 1987. Edge density, landscape shape index, fractal dimension and patch density increase variously, but the changes of pattern indexes of land for building is quite different from these types for the urbanization and nonagriculturalization of cultivated land.

Key words: LUCC, patterns index, landscape dynamics, Hangzhouwan Bay, coastal plain
