摘要
形态结构是植物对气候变化响应研究中的重要内容之一。论文分别综述了CO2浓度、气温及二者同时升高对植物株高、分枝、冠型、叶片和根系形态结构的影响。结果表明,大气CO2浓度升高促进植物的枝、茎、节间长和根系的生长,因而改变了植物的冠层结构和根系结构;单独气温升高或CO2浓度和温度同时升高对植物形态结构的影响因不同功能群、种或区域而显现出不确定性;通过对比研究,探讨了各研究结果出现差异的可能原因。最后分析了目前气候变化对植物形态结构影响研究的特点并提出未来应加强形态结构变化机理及形态结构变化与生态系统功能之间关系的研究。
Research on responses of morphology to elevated CO2 and temperature is an important content in the context of climate change. Therefore, this review firstly described the definition and conceptual framework of morphology. Then, the effects of elevated CO2, temperature and the combination of two on plant height, branching, crown shape, leaf and root system traits were summarized. The previous results showed that elevated CO2 stimulated the growth of branch, stem and internode length, resulting in the change of crown architecture. The effects of elevated temperature alone or combination of elevated CO2 and temperature on plants were various depending on functional groups, species and regions. Moreover, differences and their possible reasons in research results were discussed. In the end, we analyzed the recent research, then indicated the emphasis and direction of future study on reinforcing study on the mechanism of change in morphology and the relationship between morphology and the function of ecosystem.
