Abstract:: Based on the TM images of 1991 and ETM images of 2006, the wetlands types were classified as nature wetland and artificial wetland, and the wetland landscape of two periods was picked. The landscape pattern was analyzed based on the index of the plot area and number, fragmentation, diversity, dominance, eveness and fractal dimension. The result indicated that the plot area and number of the wetland decreased severly from 1991 to 2006, but the aquatic ponds increased. The proportion of nature wetland was greater than artifical wetland in 1991, but it was almost equal until 2006.On the landscape pattern, the diversity and eveness decreased, and the dominance increased.
