| 摘 要： | 化石燃料的燃烧和城市化进程的加快导致大气中二氧化碳(CO2)和臭氧(O3)浓度日益升高, 大气气体浓度的变化会对植物个体和陆地生态系统结构与功能产生影响。CO2浓度升高增加了陆地生态系统碳汇能力, 而O3导致作物减产和生态系统固碳损失。自由空气中气体浓度增加(FACE)系统是最接近自然的一种模拟大气气体浓度增加对生态系统影响的研究平台, 已广泛应用于各种生态系统, 为理解陆地生态系统生态过程对全球变化的响应及评估未来情景的生态风险提供了重要科学依据。该文从FACE技术特点出发, 介绍了国内外建成的大型CO2/O3-FACE系统, 分析了FACE系统的不同布气方式在不同生态系统研究过程中的优点与缺点, 概述了全球FACE运行的现状和取得的主要成果, 并指出了FACE系统存在的主要问题和前沿研究方向。 |

| Abstract: | Massive fossil fuel burning and the rapid urbanization have caused significant increases in atmospheric carbon dioxide (CO2) and ozone (O3) concentrations. The increased gas concentration has significant impacts on the structure and function of terrestrial plants and ecosystems. Rising CO2 concentration increased the plant growth and productivity, while elevated O3 decreased grain yield and carbon sequestration capacity. The Free-Air Concentration Enrichment (FACE) is one kind of facility closest to the natural conditions for simulating effects of rising atmospheric gas concentration on ecosystems. FACE has been widely used in various ecosystems and provides key basis to understand the ecological progress in response to global change and parameters for risk assessment in terrestrial ecosystem models. In this paper, CO2/O3-FACE facility around world and their technology are reviewed. The advantages and disadvantages of the design of each FACE in different terrestrial ecosystems were discussed. The current status of global FACE facility and progress in research achievements are also introduced. Furthermore, the problems in running current FACE and the frontiers of scientific questions are also highlighted. |
