Based on historical data and remote sensing data, six indices including patch number, patch area, landscape dominance index, fractal dimension, patch density and connectivity index were used to analyze landscape pattern dynamics of water body in Kaifeng city since the end of the Qing Dynasty. The results showed: 1) Since the end of Qing Dynasty, landscape area of water body in Kaifeng city had experienced a process of increase first and then decrease from AD1898 to AD2002; the landscape dominant degree had the same change with the area. 2) Patch number of water landscape in Kaifeng city increased from AD1898 to AD2002, but the area of maximum patch, the area of minimum patch and the average patch area decreased, but patch density increased, resulting in an increase in landscape fragment degree. 3) Connectivity index decreased and fractal dimension increased from AD1898 to AD2002. The reasons for these changes include both natural factors and human factors. Prior to 1949, the impact of the Yellow River predominates and after 1949, the impact of anthropogenic activities play the leading role.
