      abstract     = {Soil C and N turnover rates and contents are strongly
                      influenced by climates (e.g., mean annual temperature MAT,
                      and mean annual precipitation MAP) as well as human
                      activities. However, the effects of converting natural
                      forests to intensively human-managed plantations on soil
                      carbon (C), nitrogen (N) dynamics across various climatic
                      zones are not well known. In this study, we evaluated C, N
                      pool and natural abundances of δ13C and δ15N in forest
                      floor layer and 1-meter depth mineral soils under natural
                      forests (NF) and plantation forest (PF) at six sites in
                      eastern China. Our results showed that forest floor had
                      higher C contents and lower N contents in PF compared to NF,
                      resulting in high forest floor C/N ratios and a decrease in
                      the quality of organic materials in forest floor under
                      plantations. In general, soil C, N contents and their
                      isotope changed significantly in the forest floor and
                      mineral soil after land use change (LUC). Soil δ13C was
                      significantly enriched in forest floor after LUC while both
                      δ13C and δ15N values were enriched in mineral soils.
                      Linear and non-linear regressions were observed for MAP and
                      MAT in soil C/N ratios and soil δ13C, in their changes with
                      NF conversion to PF while soil δ15N values were positively
                      correlated with MAT. Our findings implied that LUC alters
                      soil C turnover and contents and MAP drive soil δ13C
                      dynamic.},
