Abstract

To study evolution of the characteristics of the soil aggregates organic carbon content and its fractal in the karst region of Maolan with the process of natural restoration of karst forest vegetation, the concept of space as a substitute for time was adopted. The results are as follows. The soil aggregate mass percentage(4.74% 52.37%) and its organic carbon contribution rate(2.87% 59.98%) in 1 2 mm and 0.5 1 mm soil aggregate were higher than that in 0.25 0.5 mm, -1, 1.34 22.12 g·kg-1) were more than that >20 cm layer (14.36 36.80 g·kg-1, 0.57 11.93 g·kg-1) and increased with the process of the restoration and decreased with soil depth at the same restoration stage. The organic carbon content in 1 2 mm soil aggregate (16.90 53.43 g·kg-1) was the lowest but the organic carbon content of 1 2 mm soil aggregate mass percentage (5.24 22.12 g·kg-1) was the highest among all soil aggregates. The soil aggregate fractal dimension increased in the surface layer (0 10 cm layer, 2.01 2.16) but decreased in the low layer(>20 cm layer, 2.04 2.24) along with the process of the restoration. The evolution of soil structure may be that the surface layer soil aggregates turned thin but the low layer soil aggregates turned thicken along with the process of the restoration. The soil structure was improved along with the process of the restoration. The soil aggregate fractal dimension can be used as a comprehensively quantitative index to evaluate the soil organic carbon during the process of natural restoration; It is, therefore, essential to take strong measures to preserve karst forests and let them restore naturally, which can helps improve the soil structure, less soil erosion and accumulate organic carbon.
