| 英文摘要 | Farmland afforestation has long been considered an effective approach to improve soil structure and nutrients cycling. Whereas, how the tree species and afforestation ages affect soil enzymes associated with carbon (C), nitrogen (N), and phosphorus (P) cycling at aggregate scale has been less examined. In this study, we examined the effects of farmland afforestation with legume trees (Black locust, Robinia pseudoacacia) at three stand ages (10, 20, and 30 years) and with non-legume trees (Chinese pine, Pinus tabulaeformis) at 30 years on soil organic C (SOC), total N (TN), total P (TP) and the C-, N-, and P- acquiring enzyme activities (EEAC, EEAN, and EEAP) in bulk soils and aggregates in the southern part of China's Loess Plateau. We found that afforestation with black locust significantly increased the proportion of > 2 mm aggregates and mean weight diameter (MWD) across the 10-30 years, whereas afforestation with Chinese pine reduced > 2 mm aggregates and MWD. Farmland afforestation increased SOC and TN, with greater effect occurring at greater ages for legume trees and in < 0.25 mm fraction, but uniformly decreased TP in soil aggregates. Afforestation increased soil enzyme activities, with greater effects on N enzymes for afforestation with non-legume trees at 0-10 cm and greater effects on C and P enzymes for afforestation with legume trees. In addition, EEAC and EEAN were highest in < 0.25 mm aggregate fraction, but EEAP was independent of aggregate size. The enzyme activities in > 2 mm aggregates accounted for 54 %-60 % of the activities in bulk soils. Our results suggest that enzyme activity was determined mainly by the > 2 mm aggregates and was significantly influenced by afforestation species and ages through changing soil nutrients and aggregate size distribution. |
