Abstract:: The fractal of spatial structure of erosion intensity in Yunnan Province is discussed in this paper based on GIS.Some significant conclusions are drawn: (1) A certain relationship between perimeter and area of soil erosion intensity patches objectively exists for soil erosion intensity in Yunnan Province. (2) Fractal dimensions of soil erosion intensity of Yunnan Province are calculated. It is the biggest with the very strength water erosion being 1.605, and the smallest with the fierce water erosion being 1.504.(3) The stability of spatial structure is the highest with the very strength water erosion being 0.105,second with the moderate water erosion being 0.095, and the smallest with the fierce water erosion being 0.040.(4) The average Shape Index is the highest with the fierce water erosion being 0.156,and the smallest with the micro-degree freeze-thaw erosion being 0.067.(5) The average compactness is the highest with the fierce water erosion being 0.554, and the smallest with the micro-degree freeze-thaw erosion being 0.237.
