英文摘要	The strong attitudinal gradients leading to dramatic variations in environmental conditions in mountain regions provide unique and sometimes the best opportunities to study plant responses and adaptation to global climate change. Bamboos are the fastest growing woody plants in the world. Their growth rate is highly dependent on local soil and climate conditions. To understand the responses of dwarf bamboos to global climate change, we investigated the morphological characteristics and aboveground biomass allocation of Fargesia nitida along an elevational gradient ranging from its lowest distribution boundary (2450 m a.s.l.) to its uppermost distribution limit (3200 m) in Wolong Nature Reserve, southwestern China. The structural (e.g., clump density, clump area, ramet density per clump) and morphological (e.g., leaf size, LMA, diameter, height, and biomass) responses of F. nitida to elevation are not linear but form a one-humped, convex curve with a turning point at 2850 m a.s.l., as already shown in a previous study with Q. aquifolioides carried out within the same elevational gradient on the same slope. These findings indicated that the fast-growing plants without secondary growth (F. nitida) respond to elevation similar with the slow-growing plants with secondary growth (Q. aquifolioides). The non-linear responses may be mainly resulted from a precipitation-rich zone occurred at the intermediate elevation, and reflect the non-linear changes in environmental conditions along the elevational gradient, in spite of plant species. The results also indicate the high sensitivity of F. nitida to water availability under global climate change.
