- Abstract:
- Agricultural land of Neijiang City, which is seasonal drought area and in the hilly area of central Sichuan, was chosen as the study site. The slope aspect, slope position, soil thickness were chosen as the factors influencing the soil aggregation stability. The stability of soil aggregates, fractal characteristics as well as the relationship between them were discussed by using the method of normal mean mass diameter and fractal theory. The results showed that soil aggregation stability of normal mean mass diameter in this area presented as the sequence of sunny slope>slope, downhill slope>middle slope>uphill slope, 15-30cm>30-45cm>0-15cm. It explained that the soil aggregation stability of sunny slope was higher than that in slope upward, and the soil aggregation stability of downhill slope was the highest, it was the second in middle slope, and was the lowest in uphill in terms of the slope changing, and it was the highest in the layer of 15-30cm, it was the second in the layer of 30-40cm, it was the lowest in the layer of 0-15cm with regard to soil depth. Under the condition of micro-landform, the changing characteristics of fractal dimension was in the order of slope>sunny slope>middle slope>uphill slope, 15-30cm>0-15cm. Affected by the three terrain factors, the partial correlation coefficient between fractal dimension and quality of particle size of <0.1mm was pretty lange or was to be direct proportion. The research result can provide some theoretical evidence for the use of land and agriculture cultivation.
