[Landscape pattern analysis based on boundary characteristics].
Through boundary number to the length distribution spectrum analysis, the relationships between boundary number-length and fragmentation of landscape and element were discussed. Landscape pattern indices such as diversity, evenness, heterogeneity, and spatial complicity were calculated based on boundary number and cumulative length, and these indices were compared with those based on element area proportion. The results indicated that the fast urbanization process caused complication of boundary element distribution pattern and simplification of layer structure. The distribution function parameter alpha could reflect landscape fragmentation properly, and the landscape pattern indices based on boundary characteristics was an useful supplement for traditional pattern analysis.
