图5 土壤团聚体分布及稳定性与团聚体有机碳、全氮贡献率间的RDA分析 T1C、T2C、T3C、T4C分别表示<0.053、[0.053, 0.25)、[0.25, 2.00)、≥2.00 mm粒级团聚体有机碳贡献率；T1N、T2N、T3N、T4N分别表示<0.053、[0.053, 0.25)、[0.25, 2.00)、≥2.00 mm粒级团聚体全氮贡献率；CK1、CK2、CK3分别表示CK处理的3个重复，其余处理点依次类推表示。

Fig.5 RDA analysis of soil aggregate distribution and stability with aggregate organic carbon and total nitrogen contribution rate T1C, T2C, T3C, and T4C represent <0.053, [0.053, 0.25), [0.25, 2.00), ≥2.00 mm particle size aggregate organic carbon contribution rate, respectively; T1N, T2N, T3N, T4N represent <0.053, [0.053, 0.25), [0.25, 2.00), ≥2.00 mm particle size aggregate total nitrogen contribution rate, respectively; CK1, CK2, CK3 represent three replicates of CK processing, and the remaining processing points are represented in sequence.
