Soil organic carbon storage in 20-40cm was 28.1%-49.1% in 0-100cm soil layer, so the soil layer of 0-20cm is main. The influence to SOC content and storage below 20cm soil layer is large.
混交模式变化对表层土壤的影响显著高于底层土壤,0-5cm土层有机碳含量和储量受混交模式变化的影响最大,而20-40cm土层土壤有机碳储量占0-100cm土层的28.1%-49.1%,成为贮存有机碳的主要层次,20cm以下土层有机碳含量与储量受混交模式变化的影响很小。

结果表明，从环型沼泽湿地边缘向中心，土壤剖面有机碳含量和有机碳储量变化明显。
The results showed that the content of organic carbon in soil profile and the storage of organic carbon in different soils varied obviously from margin to center of the annular wetland.
试验结果表明：以有机肥或以化肥形式配合施用NPK不但可以极大提高土壤生产力，而且有益于增加土壤有机碳储量。
The input of NPK as either organic manures or chemical fertilizers not only greatly improved soil productivity but also was of benefit to the soil as a carbon sink.
