Landscape Analysis of Forest Resources for Natural Forest

Wei Chen

Abstract

To study the landscape change of natural forest resources,FRAGSTATS package of landscape space pattern was used.Landscape Shape Index,Mean Shape Index,Area-Weighted Mean Shape Index,Double Log Fractal Dimension,Mean Patch Fractal Dimension,Area-Weighted Mean Patch Fractal Dimension,Shannon's Diversity Index,Shannon's Evenness Index,Simpson's Diversity Index,Simpson's Evenness Index,Modified Simpson's Evenness Index and Modified Simpson's Diversity Index were calculated.The results showed that Area-Weighted Mean Shape Index,Double Log Fractal Dimension and Mean Patch Fractal Dimension decreased slightly,that is the shape of patch(subcompartment) didn't change a lot.The change of forest landscape was later than that of forest resource.The change of diversity index of patches was not obvious.But Relative Patch Richness and Patch Richness Density increased rapidly.
