Abstract

Taking Schima superba-Cyclobalanpsis glauca mixed stand (SP) and Elaeocarpus sylvestris pure stand (EP) (both were transformed from degraded shrub forest (DF)) in north subtropical areas of China as test objects, the effects of different species composition on the labile organic carbon contents in 0 50 cm soil depth were analyzed. As compared with the retained DF, the soil total organic carbon (TOC), easily-oxidized carbon (EOC) and light fraction organic matter (LFOM) in both SP and EP stands increased by 52.33%-96.13% and 77.93%-119.85%, 57.89%-100.90% and 21.44%-46.85%, 74.50%-93.75% and 27.24%-96.09%, respectively. No obvious change in water-soluble organic carbon (WSOC) was observed after reforestation. The ratios of WSOC/TOC in the soils followed the order of DF >SP >EP, whereas the EOC/TOC in the soils followed the order of SP >DF >EP. In the three stands, the soil WSOC, EOC, and LFOC had extremely significant correlations with soil TOC (p<0.01), and the correlation coefficients of each labile organic carbon with soil TOC were higher in SP than in DF and EP. The soil TOC, EOC and LFOC in the three stands were extremely significantly correlated with soil nutrients, but the soil WSOC had no significant correlations with soil hydrolysable N and available K in DF, all the same, there was no significant correlation between soil WSOC and available K in EP.
- degraded shrub forest,
- species composition,
- soil labile organic carbon,
- light fraction organic matter
