中文摘要：
以大气二氧化碳（CO2）浓度升高和全球变暖为主要特征的全球变化引起了各国政府和科学家的普遍关注．植物物候节律与气候等环境因子密切相关，已有大量研究表明，植物物候已经发生并正在发生着改变．植物物候与区域乃至全球气候变化之间存在密切关联，且其在全球碳循环中扮演着重要的角色．植物物候变化可能引起一系列生态效应．CO2浓度升高对植物物候的影响没有统一的规律，而温度升高一般加速植物物候过程，且在也同一功能群内，响应的方式有一定的趋同性，两者交互作用对植物物候影响的研究仍然匮乏．
英文摘要：
Global change mainly characterized by elevated carbon dioxide concentration and global warming draws universal concerns from governments and scientists all over the world. Environmental and climatic factors are closely correlated to many plant phenological processes. There are a lot of investigations that indicate plant phenology has changed remarkably. Similarly, the changes in phenological seasonality of plants are likely to have a wide range of consequences for ecological processes. The phenological change could create some effects on regional or global climate change. Thus, plant phenology plays a crucial role in many aspects, especially in global carbon cycle. There is no immobilized regularity for the elevated carbon dioxide concentration to affect plant phenology. However, the increased temperature generally accelerates plant phenological processes, and the responses of plant phenology to increased temperature vary in different functional groups. Still, the responses of plant phenology to the interactions between the elevated carbon dioxide concentration and increased temperature need to be further studied.
