Abstract The superiority of fractal theory in describing the irregular geometry is very significant. The authors first investigated the spatial distribution pattern of soil types in the Manas River Basin, then quantitatively analyzed the scale-frequency characteristics of soil patch area and shape index based on the fractal theory and the landscape ecology principle. Main conclusions are as follows: (1)The diversity index of soil types is 2.834, and the biggest patch index is 8.885. Both indices are comparatively high, and it indicates that soil patches are dominated by a few soil types though the diversity of soil types is high in the study area. (2)The scale-frequency correlation coefficients of the patch area and the patch shape index are more than 95%, and the relationship is significant. (3)The scale-frequency correlation of the soil patch area and the patch shape index in the Manas River Basin is objective, and it is not affected by the selection of scales of the soil patch area and the patch shape index.
