| 摘 要： | 简要介绍了最近国内外植物植物生理生态学的几个热点问题，这些问题主要围绕着人类活动影响造成的几大重要环境因子改变而可能导致的植物植物生理生态变化展开，包括CO2浓度升高、紫外辐射增加，温度变化，强光、盐生环境扩大化等；部分工作探讨已经存在的特殊生境下的植物生态适应。其中，围绕着陆地生态系统的碳平衡是最为热门的话题之一。虽然以CO2浓度升高主题展开对C3和C4植物的影响研究依然是众多刊物发表生理生态学原始论文的重要内容，一些特殊功能如CMA植物的响应引起了人们的兴趣，植物对于紫外辐射的生理生态响应有望成为新的研究热点，研究手段的完善以及实验材料的改进是最近植物植物生理生态学不断出新成果的重要原因之一，如稳定同位素技术的应用、野外FACE实验、叶绿素荧光技术等使一些机理性问题不断被揭示出来。

| Abstract: | Some hot topics in plant physioecology research have recently made regular appearances in a number of important international journals (Science, Nature, etc.). These describe the responses of plant physioecology and growth to factors such as: increasing CO_2 concentration, ultraviolet radiation enhancement, changes in temperature, sunlight irradiation and the enlargement of salty habitats. All of these factors are closely associated with the processes of global climate change. Some of the research, however, aims to investigate the response of plants to existing environmental stresses in specialised environmental habitats. Among the intensive studies, the carbon budget of terrestrial ecosystems is one of the hottest topics, research conducted recently, including: the emission of greenhouse gasses, sink and source dynamics of carbon at regional and global scales and the function of the terrestrial and oceanic ecosystems. Although the responses of C_3 and C_4 species to elevated CO_2 are still the main topics in most journals, there has been much progress in study of CAM functional types. Progress in the application of new technologies such as stable isotope methods, free air CO_2 enrichment (FACE) facilities, and chlorophyll fluorescence technology have helped greatly in understanding these general problems. |
