| Abstract: | On the basis of the techniques of remote sensing and geographical information system (GIS)，it is possible to extract water information from the remotely sensed images for mapping and pattern study by using the method of spectrum relations. In this paper, water information was derived from the remote sensing images of Shanghai section obtained on the northern bank of Hangzhou Bay in 1992，2001 and 2008, respectively. The landscape information including a number of patches，areas，densities，shape indices and fractals were calculated for further analysis. The results show that the landscape pattern of water was changed remarkably with the reduction of total area and patches as well as the complication of the water shape from 1992 to 2008. |
