Based on the interpretation of TM images, the theory of landscape-ecology and the method of quantitative analysis, the characteristics and changes of landscape pattern in Hangzhou city during the past 15 years (1991—2005) were analyzed and meanwhile the driving force of landscape changes were discussed based on canonical correspondence analysis (CCA) method. The results showed: (1) The land-use landscape pattern changed greatly, mainly the area of farming landscape and water landscape declined significantly, but the area of building landscape increased, which of 43.85% came from farming landscape; (2) Number of patches (NP) and Shannon’s diversity index (SHDI) and fragmentation (FN1) increased, however, the dominance (D) decreased. These results showed that landscape pattern would became smaller and smaller; (3) CCA method clearly demonstrated the correlations and spatial feature between landscape pattern indices and driving forces at eight districts in Hangzhou city.
