Abstract:
In order to understand the spatial distribution characteristics of the soil organic carbon in the secondary forest of the Changbai Mountains，the sample line method was adopted to carry out the research about the secondary forest soil organic carbon in the Changbai Mountains as well as the spatial distribution characteristics of organic density in soil profile layer，slope position and aspect.The results showed that the secondary forest soil organic carbon decreased with the increasing of the depth of soil profile except the middle soil profile (A 1-2) in the east slope in the east-west sampling line.The total organic carbon in 0-5 cm humus layer was significantly higher than the illuvium.The content of the organic carbon in the humus layer in the secondary forest of the Changbai Mountains was influenced by the slope aspect in different heights of the mountain，in the east-west sampling line，the soil organic carbon increases with the increasing of the altitude，but the results collected in the east-south sampling line was different from the the former.In the secondary forest，the carbon densities and its vertical space distributions in different mountains were significantly different.The densities of the organic carbon for the all two sampling lines were between （0.6±0.1）×105 kg/hm2 and （1.6±0.2）×105 kg/hm2 in the secondary forest in east the Changbai Mountain.
