Dynamic Changes Analysis of Dangshan Landscape Pattern

The article takes 2 TM images as the data source, supported by the Fragstats 3.3 and the ENVI 4.7 softwares, two remote sensing images are classified by the support vector machine method, selects the number of patches (NP), edge density (ED), patches density (PD), landscape shape index (LSI), perimeter area fractal dimension (PAFRAC), interspersion juxtaposition index (IJI), patch cohesion index (COHESION), Shannon's diversity index (SHDI), Shannon's evenness index (SHEI) and contagion index (CONTAG), using the landscape ecological principles and methods, analyzes the dynamic changes of Dangshan landscape patter in 1987-2009, with a view to Dangshan county land resources of reasonable planning and using, management, sustainable utilization, and the landscape pattern optimization configuration, provides the theory foundation and scientific basis.
