Analysis of Forest Landscape Pattern in Mount Tianmu National Nature Reserv

Mount Tianmu National Nature Reserve in Zhejiang Province was taken as the study object, the terrain map, remote sensing images and the data required by the 2nd class forest management inventory were collected to analyze the characteristics of the forest landscape pattern. The forest landscape of Mount Tianmu National Nature Reserve was classified into five types of forest landscape patches including broadleaved forest, coniferous forest, coniferous and broadleaved mixed forest, nontimber product forest and bamboo forest. The forest landscape was classified into two categories, i.e., the natural landscape and the seminatural landscape. Then, the patch density, shape index, diversity index and dominance index, etc. were selected as landscape pattern indices which were used in analyzing forest landscape characteristics based on GIS and RS techniques. The results showed that the patch density and the separation index of nontimber product plantations were the biggest, and those of the broadleaved forests were the least. The patches of bamboo forest had the most complex shape feature, while the nontimber product plantations had the most regular patch shape. The landscape diversity indexes were ordered as the whole landscape > natural landscape > seminatural landscape, whereas the order of the dominance indexes was that the seminatural landscape > the whole landscape > natural landscape.
