图2. 氮磷添加对土壤有机碳组分影响的潜在机制。颗粒态有机碳和矿物结合态有机碳为粒径分组得到的组分, 轻组分有机碳和重组分有机碳为密度分组得到的组分, 它们的性质分别类似。
Fig. 2. Potential mechanisms of how nitrogen (N) and/or phosphorus (P) addition affect the fractions of soil organic carbon (C). Particulate organic C (POC) and mineral-associated organic C (MAOC) are the fractions separated by size fractionation, light-fraction organic C (LFC) and heavy-fraction organic C (HFC) are the fractions separated by density fractionation, and the characteristics of POC vs. LFC and MAOC vs. HFC are similar, respectively.
