Abstract:: Mountain red earth is the relic ancient clay remained on the Yunnan Plateau formed under the influence of paleoclimate, however, this soil has experienced degradation recently. To understand the texture and the degree of degradation of mountain red earth, this study examined the mountain red earth based on the analysis of soil profile particle volume fractal dimension (FD) associated with different vegetation types. Particularly, soil samples were taken from areas covered with pineland, shrubland, grassland or unvegetated red soils respectively in the karst area of east Yunnan. The results indicated that FD varied from 2.734 to 2.789, which overall belonged to the silty clay loam. Soil FDs of shrublands, grassland, and pineland became larger with the increase of depth, while red bare soil presented the opposite trend. And the relationship between the content of clay particle and the FD in the soil profile showed the same trend while the distribution charateristics of sand and silt in the soil profile were not obvious. There was a significantly positive correlation between FD and clay which was mainly decided by the clay. FD was negatively correlated with coarse sand, and positively correlated with fine sand and silt. So FD can be expressed in a uniform degree of soil texture in the mountains red earth of degradation process, and an important indicator to determine differences in soil texture. FD was significantly positively correlated with organic matter, and negatively correlated with potassium, available phosphorus, and nitrate nitrogen. Therefore, FD can be used to describe the fertility levels of degradation of mountain red earth fertility characteristics of the soil profile.
