英文摘要 | Afforestation is regarded as an effective way to sequester soil organic carbon (C) and hence to attenuate global warming. Nevertheless, so far mechanisms underlying the direction and magnitude of soil C pool variation following afforestation are not well understood. Here soil organic C, total nitrogen (N) and total phosphorus (P) pools in surface mineral soil (0-15 cm) were measured in cropland and plantation forest over two lithology types, i.e., limestone and clasolite, using a paired-site approach in a region of southwest China. The major objective was to test whether the effects of afforestation on soil C, N and P pools were affected by lithology. We found that lithology modulated the effect of afforestation on soil C or N pool, but not on soil P pool. Soil C pool was not altered by afforestation over limestone, but was significantly increased over clasolite (P < 0.001). Instead, soil N pool was significantly decreased by afforestation over limestone (P < 0.001), but was not altered over clasolite. Soil P pool was consistently decreased by afforestation regardless of lithology type (P < 0.05). The molar ratios among soil C, N and P were not affected by lithology, but were significantly elevated by afforestation (P < 0.01), indicating that soil C sequestration would increasingly be limited by soil N or P following afforestation. Our study suggests that afforestation effects on soil C and N pools may be controlled by lithology, and thus provides a new mechanism to explain the divergent responses of soil C and N following afforestation.
