The Analysis on the Patch Fractal Figure of All Land Use Types in Shucheng County
The paper used fractal theory to do the quantitative analysis on the perimeter of patches of all land use types, patches' edge densities and the scale-frequency relation of patches' shape indexes. The result showed that from plain to hillock, and then mountains, the number of all land use types' patches gradually reduced, landscape heterogeneity and landscape fragmentation decreased; the dominant patch in plain was arable land, and in hillock was arable land and woodland, while in mountain areas the patch was woodland; patches' edge densities were generally high and the edge of all land use types' patches tended to be complicated; patches' shape indexes were commonly not high, and patches' shape was relatively simple; the scale - frequency's double logarithmic relationship of the perimeter of patches, patches' edge densities and patches' shape indexes relation were respectively evident. And the correlation coefficient were all more than 0. 9 and showed highly negative correlation , that is, the fractal relationship was objective. It accelerates the further research on the fractal dimension between the perimeter and area of all land use types' patches, and the complexity and stability of patches.
