摘要: 北极不同地区的气候和植被类型的差异导致不同类型生态系统的碳收支差异。北极独特的生态系统以及对气候变化的响应的“放大效应”使北极地区对全球气候变化最为敏感。北极地区的碳循环对于全球气候变化反馈越来越重要。为了研究北极地区不同生态系统的碳循环过程，本文使用北极地区附近两组配对试验站的相关站点观测资料、FLUXNET网站上的部分资料。通以涡度相关方法为主要技术方法，探讨了2003年芬兰Hyytiala，Jokioinen和2010年格陵兰Zackenberg地区的净生态系统碳交换NEE的月动态，季节动态和年动态以及环境因素的影响机制。植被是影响生态系统碳收支的重要因子，生态系统通量和陆地上生物量具有显著的正相关关系。
Abstract: Differences in climate and vegetation types in different parts of the Arctic lead to differences in carbon budgets of different types of ecosystems. The Arctic’s unique ecosystem and the “amplifica-tion effect” of its response to climate change make the Arctic most sensitive to global climate change. The carbon cycle in the Arctic is increasingly important for global climate change feedback. In order to study the carbon cycle processes of different ecosystems in the Arctic region, this paper uses ob-servations from relevant sites of two pairs of test stations near the Arctic region and some data on the FLUXNET website. Using the vorticity-related method as the main technical method, the month-ly, seasonal and annual dynamics of net ecosystem carbon exchange NEE in hyytiala and Jokioinen of Finland in 2003 and Zackenberg in Greenland in 2010 were discussed, and environmental factors were discussed. Vegetation is an important factor that affects the carbon budget of ecosystems, and ecosystem flux has a significant positive correlation with terrestrial biomass.
