Ninety-nine soil samples (GPS used for recording sample location) were collected in the Jiangjiagou Ravine, Yunnan Province, China, a frequent debris flow occurring area, in order to statistically investigate the spatial variation characteristics of soil organic matters. The results indicated that the average content of soil organic matters (2.21 g/ kg) was at a low level. The soil organic matters in space presented an obvious anisotropy, and spatial variation characteristics mainly existed in the northeast-southwest direction with the strip shape. The spatial variability of soil organic matters was controlled by both its auto-spatial dependence and random factors, and the soil organic matters displayed medium degree of spatial correlation. Furthermore, the distribution of soil organic matters was influenced by soil texture, slope, elevation, land use types and human production activities. Under different levels of a certain factor, the soil organic content showed extremely significant difference. The results can provide a basis for carbon reserves estimation in debris flow ravine, and the reference for ecological restoration and reconstruction in the area with soil erosion degradation.
