摘要
对减缓全球气候变化与温室气体“汇”的最新研究进展作了较为详尽的综述。针对目前温室气体汇研究中的主要前沿科学问题进行了深入分析：包括汇的定义、种类及方法学问题，土地利用变化和森林以及农业土壤汇的种类及计算中存在的一些问题，人类活动对自然生态系统源汇状况的影响等；还对估算各种温室气体源汇的不确定性作了分析总结；在列举了一些气候变化框架公约缔约国及发展中国家对《京都议定书》中引入温室气体“汇”的看法及态度后，提出了在编制温室气体国家清单及估算“吸收汇”计算过程中应注意的问题。
Global warming has been becoming a world wide issue in which anthropogenic emission of greenhouse gases plays a main role. The emission processes of greenhouse gases have been drawn great concern by researchers domestically and abroad. Kyoto Protocol introduced the greenhouse“sink”, it would influence the completion of greenhouse gases and the implementation of quantified emission limitation or reduction commitment (QELROs). In this paper, recent advances on the greenhouse “sink” were reviewed and analyzed, include: ①the definition, type , and account method of “sinks” of greenhouse gases; ②types and account method on “land use change and forestry”; ③the influence of human activities on sources and sinks of ecosystems such as forests, grasslands and croplands. The uncertainty on accounting the sources and sinks of greenhouses was analyzed too. Views on accounting national inventory and sinks of greenhouse gases were analyzed.
