Based on the RS images of Landsat TM in 1994 and Landsat ETM+ in 2002, information on landuse in different periods is extracted,and changes in landuse and landscape pattern of Pingdingshan City are studied.The main tendency of landuse change was that the areas of cultivated land and wood land decreased greatly,and however,the areas of urban land,industry and mining land and weed land increased greatly.The comprehensive landuse index decreased remarkably.Landscape structure and landscape heterogeneity also changed greatly,for patches density,diversity index,dominance index and the evenness increased.The largest patch index and the landscape shape index decreased.At last,the countermeasures for sustainable ecological development are brought forward.
