Abstract: The analysis on the coastal landscape pattern evolution has great significance to understand the relationship between human activities and landscape pattern evolution, and to promote the sustainable development of coastal area. Based on the Landsat TM images of 1990, 2000 and 2010, landscape pattern evolution of coastal zone around the Xiangshangang Bay was analyzed by using “3S” techniques. The results showed as follows: (1) The areas of the woodland, the sea and the farmland decreased, while the construction land, water area, aquaculture land and unused land increased, and the area of beach increased at first and then decreased. (2) The patch number (NP), the patch density (PD) increased, the mean patch area (MPS) decreased, the perimeter density (ED) and the shape index (LSI) increased, Shannon's diversity index (SHDI) and Shannon's evenness index (SHEI) increased, and the landscape heterogeneity increased. (3) The whole dynamic degree showed a rising trend, and the landscape of coastal zone around the Xiangshangang Bay changed more frequently because of human activities intensity about development and utilization. (4) Human activities and natural factors led to the landscape pattern evolution of coastal zone around the Xiangshangang Bay.
