Abstract

Based on the land use data interpreted from TM and ASTER images of Hangzhou Xixi Wetland in 1991, 2001 and 2005, in this paper, we first study the spatiotemporal diversity of urban growth and the evolution of urban landscape pattern in Hangzhou Xixi wetland during the rapid urbanization by calculating the indexes of landscape pattern such as Fractal Dimension, Peri-Area Ratio, Fragmentation, Shannon-diversity. The results showed that (1) the spatial landscapes from class level and landscape level have evident differences, (2) from class level, the changes of the main landscape in Southeast area were very complicate, and wetland and forest in Core area have the bigger Fractal Dimension and small Fragmentation, (3)from Landscape level, the Fragmentation and Shannon-diversity were bigger and the Dominance and Contagion have decreased, (4)the landscape in different times has different changes from wetland dynamic change,(5)during the process from the urban edge wetland to urban wetland, the landscape pattern change of Xixi urban wetland have evident differences because of the human influence.
