    Abstract
  • To explore the relationship between physical protection and chemical protection on soil organic carbon is helpful to reveal the mechanism of soil carbon sequestration and fertility. It could also ascertain the contribution of different components of soil aggregates, humic substances in soil carbon sequestration and soil fertility. The content of humus in soil aggregate of natural vegetation in karst area was studied. The results showed that: (1) In general, the content of soil organic carbon decreased with the increase of soil depth, and the variation of organic carbon content is different at soil depths with variation of aggregate size. (2) The contents of humic and fulvic acids in the soil aggregates are lower than that in mass soil. This may be because the soluble components of humic and fulvic acids get lost in sieving aggregates. (3) The decrease of humus content along with the soil aggregate size in the two types of natural vegetation not obvious. However the total content of humic and fulvic acids gradually increase along with the decrease of soil aggregate size, that is, the maximum content of humus is in those soils with aggregate size of less than 0.25mm. (4) HA/FA is less than 1 in both the mass soil and the aggregate of two kinds of natural vegetation, which is mainly because of the relatively high temperature, high humidity, thick vegetation coverage, strong microbial degradation of the study area.
