Accessing the impacts of bamboo expansion on NPP and N cycling in evergreen broadleaved forest in subtropical China.

ABSTRACT: Bamboo (Phyllostachys pubescens) expansion into adjacent forests is a widespread phenomenon in subtropical regions, and it has greatly changed the dominance hierarchy from trees to bamboos. This process may be accompanied by changes in productivity, nutrients accumulation and biogeochemical cycles. We compared the net primary production (NPP) and major pools and fluxes of nitrogen (N) in bamboo-dominant forest (BDF) and neighboring secondary evergreen broadleaved forest (EBF) in South China using the space-for-time substitution method. We found that the mean NPP of the BDF was 30.0 t ha^-1 yr^-1, which was 51.5% greater than that of the EBF (19.8 t ha^-1 yr^-1). The plant N pool for the BDF was 37.5% larger than that of the EBF, whereas the soil inor
