| 摘 要： | 多年冻土区储存着大量的土壤有机碳， 其碳库变化及生态系统碳反馈机制是当前全球气候变化研究中备受关注的热点问题。为了增强对多年冻土碳循环的认识， 通过综合第三极和北极地区多年冻土碳循环研究， 概述了土壤有机碳库大小、 脆弱性及生态系统碳交换过程， 分析了涉及大气、 海洋和陆地综合影响的多年冻土区生态系统碳循环。研究表明： 第三极和北极多年冻土区碳储量不确定性较大， 影响和控制有机碳分解和生态系统碳交换的生物地球化学过程仍需进一步研究， 进而改进生态系统碳循环相关的模拟研究。在全球气候变化背景下， 研究多年冻土碳库变化及其对气候变化的响应， 是预估未来气候变化的关键环节。

| Abstract: | Large quantities of organic carbon are stored in permafrost regions， and the change of permafrost carbon pool and the feedback of ecosystem carbon to climate change are important issues in current global climate change research. To enhance the understanding of the process of ecosystem carbon cycle， we state a comprehensive research of carbon cycle in the Third Pole and the Arctic. The size and vulnerability of permafrost carbon pools and the processes of ecosystem carbon exchange were summarized. Meanwhile， the permafrost carbon cycle involved the combined effects of air， sea and land were also analyzed. This research shows that there is greater uncertainty of carbon storage in the Third Pole and the Arctic permafrost regions. What’s more， the biogeochemical mechanisms controlling the carbon exchange of alpine ecosystems still need further studies. Under climate change scenarios， the change of permafrost carbon pool and its response to climate change is a key part in predicting future climate change. |
