摘      要：Increasing field experiments have been conducted in forests to better understand the response of plant growth and photosynthesis to climatic warming. However,it is still unknown whether there is a general pattern in relation to how and to what extent warming impacts woody plants in forests. In this study, a meta-analysis was conducted to investigate the warming effects. When temperatures increased between 0.3 and 10 ℃, specific leaf area(SLA) was significantly increased by 5.9%, plant height by 7.8%, biomass by 21.9%, foliar calcium(Ca) and manganese(Mn) concentrations by 20.7% and 39.6% and net photosynthetic rate(Pn) by 9.9%. Enhanced growth and Pn may have a relationship with changing SLA, efficiency of PSⅡ(photosystem Ⅱ), photosynthetic pigment concentrations and foliar nutrients. The results will be useful to understand the underlying mechanisms of forests responding to global warming.
