- Abstract:
- In order to research the effect of altitude on the characteristics of soil aggregate and its stability in High-Frigid Mountainous region, based on field investigation and experimental measurement, we determined soil aggregate along altitude gradient. The results showed that the content of >0.25 mm air-dried aggregate was greater than 80%, the content of water stability aggregate was greater than 70%; the content of >0.25 mm air-dried aggregate in 0—60 cm soil layer increased with increase of altitude, and the content of soil water stability aggregate decreased at first and then increased with increase of latitude; the organic matter content of >0.25 mm aggregate was highest, it increased at first and then decreased with increase of latitude, and decreased with increase of soil depth; mean weight diameter and geometric mean diameter decreased with decrease of altitude, while fractal dimensionality in 0—20 cm soil layer showed the increasing trend, but the pattern wasn’t obvious in >20 cm soil layer. These results indicated that the surface soil structure stability was better in the alpine mountain of western Sichuan, and prevention of soil degradation should be the focus of ecological protection in this area.
