Overall, the results showed that compared with the control, under rainfall decreased conditions, the leaf area (LA, -24.80%), specific leaf area (SLA, -6.78%), net photosynthetic rate (Pn, -31.38%), transpiration rate (Tr, -27.60%), and stomatal conductance (Gs, -20.95%) were decreased significantly (P<0.05), while the water use efficiency (WUE, 3.71%) was significantly increased. Under conditions of rainfall increase, the LA (8.07%), Pn (24.60%), Tr (23.94%), Gs (26.73%) and WUE (5.75%) were increased significantly (P<0.05), and Ci (-2.04%) was decreased significantly compared to that of the control. The results of subgroup analysis showed that desert steppe or arid areas were respectively sensitive to rainfall increase, while meadow steppe or humid areas were respectively sensitive to rainfall decrease. Under rainfall enhancement conditions, grasses or dominant species tend to adopt acquisitive strategies, while under rainfall reduction conditions, they turn to conservative strategies. This study clarifies the differentiated responses of grassland plants in northern China to rainfall changes, providing a scientific basis for predicting the stability and functional evolution of grassland ecosystems under climate change., authors=WANG Yi-ming1, YANG Jie1, ZHANG Xiao-juan1, YUE Lei1, MA Jing1, YANG Jian1, TANG Zhuang-sheng1, authorsList=WANG Yi-ming, YANG Jie, ZHANG Xiao-juan,

articleAbstract=为揭示中国草原植物对降雨变化的响应规律及适应策略,本研究采用Meta分析,系统分析了降雨变化对不同草原(草甸、典型及荒漠草原)及不同功能群植物叶片功能性状与气体交换参数的影响。结果表明:与对照相比,减雨条件下叶面积(Leaf area,LA,-24.80%)、比叶面积(Specific leaf area,SLA,-6.78%)、净光合速率(Photosynthetic rate,Pn,-31.38%)、蒸腾速率(Transpiration rate,Tr,-27.60%)、气孔导度(Stomatal conductance,Gs,-20.95%)显著下降(P<0.05),而水分利用效率(Water use efficiency,WUE,3.71%)显著提高。增雨条件下LA(8.07%)、Pn(24.60%)、Tr(23.94%)、Gs(26.73%)与WUE(5.75%)显著上升(P<0.05),胞间二氧化碳浓度(Intercellular carbon dioxide concentration,Ci,-2.04%)显著下降。亚组分析结果表明,荒漠草原或干旱区对增雨敏感,而草甸草原或湿润区对减雨敏感,禾本科或优势种植物在增雨条件下倾向于获取性策略而在减雨条件下转向保守型策略。本研究阐明了中国北方草原植物对降雨变化的差异化响应,为预测气候变化下草原生态系统稳定性及功能演变提供了科学依据。, authors=王一鸣1, 杨洁1, 张晓娟1, 岳磊1, 马晶1,

To reveal the response patterns and adaptation strategies of grassland plants in China to rainfall changes, in this study we adopted a meta-analysis to systematically analyze the effects of rainfall changes on leaf functional traits and gas exchange parameters of plants in different grasslands (meadows, typical, and desert steppes) and different functional groups. Overall, the results showed that compared with the control, under rainfall decreased conditions, the leaf area (LA, -24.80%), specific leaf area (SLA, -6.78%), net photosynthetic rate (Pn, -31.38%), transpiration rate (Tr, -27.60%), and stomatal conductance (Gs, -20.95%) were decreased significantly (P<0.05), while the water use efficiency (WUE, 3.71%) was significantly increased. Under conditions of rainfall increase, the LA (8.07%), Pn (24.60%), Tr (23.94%), Gs (26.73%) and WUE (5.75%) were increased significantly (P<0.05), and Ci (-2.04%) was decreased significantly compared to that of the control. The results of subgroup analysis showed that desert steppe or arid areas were respectively sensitive to rainfall increase, while meadow steppe or humid areas were respectively sensitive to rainfall decrease. Under rainfall enhancement conditions, grasses or dominant species tend to adopt acquisitive strategies, while under rainfall reduction conditions, they turn to conservative strategies. This study clarifies the differentiated responses of grassland plants in northern China to rainfall changes, providing a scientific basis for predicting the stability and functional evolution of grassland ecosystems under climate change.
