Analysis and Appraisal on the Present Status of Landscape Pattern of Land Resources in Anning Municipality

Based on the information from Landsat ETM images and fundamental geographical information data, the present landscape patterns of land resources in Anning Municipality were analyzed by means of the RS and GIS technology and by applying the mean matrix area, contour index, fractal dimension, Shannon-weiner diversity index, shannon-weiner evenness index and the dominance index as the study indices. It was showed by the results that the principal matrixes of the landscape pattern in Anning were the farmland, pinus yunnanensis forest and Pinus yunnanensis var. pygmaea forest lands. The fractal dimension index indicated that the shapes of water bodies and wasteland became more regular, while the road landscape form became more complicated along with the transformation process, showing that the primary natural landscape were greatly disturbed by human activities. SHDI showed that there were varied landscape types indicating high heterogeneity, while SHEI showed that farmland and forests of Pinus yunnanensis and Pinus yunnanensis var. pygmaea were the dominant landscape types in Anning Municipality.
