| 摘 要： | 高寒草甸是广布于青藏高原的主要植被类型,它是青藏高原大气与地面之间生物地球化学循环的重要构成部分,在区域碳平衡中起着极为重要的作用。基于对青藏高原主要高寒草甸生态系统类型CO2通量研究方面的综述,系统分析了高寒草甸生态系统CO2通量日、季、年等不同时间尺度的变化特征以及温度、光合有效辐射、降水等主要环境因子对高寒草甸生态系统CO2通量的影响;同时,结合其他地区草地生态系统,就青藏高原三种典型高寒草甸生态系统类型源汇效应和Q10值进行了比较;最后,结合青藏高原高寒草甸生态系统CO2通量研究的现实与需要,提出了当前存在一些不确定性和有待深入研究的问题。

| Abstract: | Alpine meadow is the key vegetation widely distributed on the Tibetan Plateau.Alpine ecosystem is the great important part in biogeochemical cycle between air and the ground surface.And it plays an extremely important role in carbon balance in this area.Research about CO2 flux of alpine ecosystem is reviewed in this article.The variations of carbon dioxide fluxes of alpine meadow ecosystem and its effecting factors were summarized on the Tibetan Plateau.The alpine meadow ecosystem is hypothesized to play an important role in the carbon balance in both regional and global ecosystems.Furthermore,the potential of source/sink and value of Q10 were compared between typical alpine meadow ecosystems and others.Lastly,some uncertainties and problems needed deeply researched are raised in this article. |
