Abstract:: In order to understand different forest age poplar plantation in Yellow River Flood Plain on soil aggregate and organic carbon, 3-year, 5-year, 8-year, 10-year poplar plantations in Dongming state-owned forest farm in Shandong Province were selected as the research objects, field sampling, laboratory test and wet screening method were used to analyze the soil aggregate composition and stability, and analyze the variation characteristics of soil organic carbon content and reserves. The results showed as follows.(1)Soil macroaggregates(> 0.25 mm)were the main aggregates in poplar plantations of different ages. In the topsoil layer(0—20 cm), the content of macroaggregates was firstly significantly decreased, then increased and then slightly decreased with the increase of stand age. However, in the 20—40 cm soil layer, the content of large aggregates was 5-year>8-year>3-year>10-year. There was no significant difference in the 40—60 cm soil layer.(2)In the 0—20 cm soil layer, the organic carbon content was 3-year>5-year>10-year>8-year. In the 20—60 cm soil layer, it showed a trend of increasing first and then decreasing, and there was no significant difference. Soil stability is closely related to the formation of aggregates and organic carbon, and the content of organic carbon is positively correlated with GMD value.(3)The organic carbon storage of poplar plantations in different ages showed a certain degree of surface aggregation, and the carbon storage in 0—20 cm layer accounted for 59.17%～74.26% of the total carbon storage. From 3-year to 5-year, soil leaching may lead to the transfer of organic carbon storage from the topsoil layer(0—20 cm)to the bottom soil layer(20—60 cm), while from 8-year to 10-year, the transfer of organic carbon storage from the bottom soil layer to the surface soil layer. The results can provided a reference for revealing the formation of soil aggregate structure and the improvement of organic carbon in poplar plantation in Yellow River Flood Plain.
