| 摘 要： | 环北极多年冻土区作为全球碳库的重要组成部分，它以一种独特的方式响应着气候变化。在气候变暖的背景下，冻土中的有机碳将在全球碳循环中扮演着更活跃的角色。为增进对环北极多年冻土区碳循环的认识，分析了近年来北极多年冻土区碳储量和碳迁移状况，以及相关模型在模拟碳循环应用方面的最新进展。目前，对北极多年冻土区碳源/汇的时空分布格局、碳循环过程的关键驱动因子以及碳循环对全球变化的响应等一系列问题尚不能作出完整的、系统性的科学解释。同时，还进一步分析了北极多年冻土区碳循环模拟的三大不确定性因素。基于以上分析，提出未来对北极多年冻土区碳循环的研究还应在典型研究区开展长期的野外系统监测、创新研究方法，深化碳循环机制研究，重视学科交叉以及多模型集成，宏观与微观相结合、多途径与多尺度综合研究。

| Abstract: | The circum-Arctic permafrost regions are important parts of the global carbon pool and respond to climate change in a unique way. With global warming,permafrost carbon will play a more active role in the global carbon cycle. To enhance the understanding of the carbon cycle in the permafrost regions of the circum-Arctic, in this paper,the carbon storage and carbon mobilization in the permafrost regions in recent years are analyzed, and the latest developments in the simulation of carbon cycle applications were also carried out. It is revealed that a complete and systematic scientific explanation for a series of problems such as the spatial and temporal distribution pattern of carbon sources/sinks,the key driving factors of the carbon cycle process,and the response of the carbon cycle to global change in the Arctic permafrost regions are still not available at present. The three uncertainties about carbon cycle simulation in the Arctic permafrost regions also analyzed. It is proposed that the future research should carry out a long-term field system monitoring in some typical research regions,innovative research methods and effective use of multi-source remote sensing data,to deepen the research on carbon cycle mechanism and reduce uncertainty. Interdisciplinary and multi-model integration,combination of macro and micro,as well as multi-path and multi-scale comprehensive study,should be emphasis. |
