Abstract
The sediment in the parts of Yitong river, located at the central of Jilin province, was taken as the research object, and the organic-mineral complex of soil samples was grouped by the improved colloid grouping method described by Qiulin. The distribution characteristics of the organic carbon in sediment organic-mineral complex were studied. The results showed that the organic carbon absolute contents in different groups were G2>G1>G0 group in <10μm and <2μm sediment organic-mineral complexes. The absolute content of organic carbon in G2 group was the highest, but G1 group had the highest relative content, which indicated that in three groups of sediment, G1 had a very prominent effect on organic carbon accumulation.
