Data were collected cover from 1982 to 1995, and classified into four major land-use types for analysis which including water land, agricultural land, built-up land and others. Markov Chain model was used to derive equilibrium matrices from different land-use types which showed the tendency of land-use change. This research used patch shape and patch disperse two landscape indices to analyze the water patches in Tao-Yuan terrace. Finally, cluster analysis was employed to group 12 towns based on their indices and centroid locations. The results showed that the characteristics of water-patches change reflect the development of Tao-Yuan terrace, and it may be helpful in exploring more information about land-use changes.
