The spatial variability and interpolation of organic matters in the red eroded soil in South China were studied by means of GIS spatial analysis and statistics.The result showed that the organic matter content in the soil was generally low.The content did not vary significantly with the elevation.At high altitudes,the areas with high organic matters constituted approximately 26% of that total area.The content of organic matters increased with steepness of the slope,where it varied from 24.05% to 34.53%.
