      abstract     = {Background and aimsLand cover change (LCC) from natural
                      forest (NF) to plantations (PF) has occurred worldwide over
                      the past several decades. However, the different LCC effects
                      on soil aggregate C and N turnover in various climatic zones
                      remain uncertain.MethodsSoil samples were taken from both NF
                      and PF at five sites along an approximately 4200 km
                      north-south transect in eastern China. We measured soil
                      aggregate C and N concentrations, and δ13C and
                      δ15N.ResultsThe soil aggregate distribution is similar
                      between NF and PF, except that the mass proportion of
                      microaggregate is lower in NF. The impacts of LCC on soil C
                      and N concentrations, and δ13C and δ15N vary among five
                      climate zones. The changes in soil aggregate C and N
                      concentrations and δ15N induced by LCC show nonlinear
                      relationships with climatic factors (i.e., MAT and MAP), and
                      there is a linear relationship between soil aggregate
                      Δδ13C (calculated by subtracting PF from NF) and MAT and
                      MAP. The soil aggregate C and N concentrations, and δ13C
                      and δ15N show clear trends along the climatic transect. In
                      addition, the impacts of LCC are more obvious in topsoil
                      than in subsoil.ConclusionOur findings highlight that the
                      impacts of LCC on soil C and N concentrations are related to
                      climatic factors. Specifically, that the increased
                      decomposition of soil C in PF than NF can be compensated by
                      higher C inputs with increasing MAT and MAP.},
