Landscape gradient characteristics was analyzed quantitatively based on GIS approach for LuoGang section of Guangzhou.The following conclusion was drawn: First,forest landscape is still dominated by covering 53% of total area,while Planned urban area consisted 2.57% of the area,which represented an unstable landscape pattern;Second,The urbanization center and frontier could be identified precisely with class-level landscape indices.Different landscape types exhibited distinctive spatial signatures along the Gradient’s part;Third,landscape fragmentation and heterogeneity induced by the urbanization could be quantified by landscape-level indices,Furthermore the shapes of landscape becomes more and more complicated,landscape tended to become more diverse.
