从《IPCC 2006国家温室气体排放清单增补:2013湿地》谈湿地温室气体计量进展及问题

A Discussion on Quantification of Greenhouse Gas Emissions from Wetlands Based on “2013 Supplement to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories: Wetlands”

通过对《IPCC 2006国家温室气体排放清单增补:2013湿地》出台的背景、湿地类别的划分、温室气体计量方法学进行解读,从温室气体排放源、计量方法和排放因子3个方面对湿地温室气体排放的计量进行了分析,重点探讨了对《IPCC 2006国家温室气体排放清单指南》中方法学的更新与改进,结合我国湿地研究的现状,进一步指出我国湿地研究中亟待解决的关键问题和未来研究的主要方向,为我国湿地排放清单指南的编制提供了理论指导。

To fill the Gaps of Greenhouse Gas （GHG） inventory for wetland in “2006 IPCC Guidelines for National Greenhouse Gas Inventories” （“IPCC 2006”）, the “2013 Supplement to the 2006 IPCC Guidelines for National Greenhouse Gas （GHG） Inventories： Wetlands” （“ Wetlands Supplement”） was published to public on February 28, 2014. The“Wetland Supplement” was reviewed from the aspects of the background, the division of wetland types and the methodology for GHG inventory. The GHG methodology was investigated from GHG emission source, GHG account methods and GHG emission factors. Especially, the updates and improvements for the “IPCC 2006” were emphatically discussesd. In general, the “Wetland Supplement” provided the new estimation methods of GHG emissions and removals from coastal wetlands and constructed wetlands for wastewater treatment by human activities, and also updated some key emission factors for various types of wetlands. Considering the present situation in China, the problems demanding prompt solution and the future research trend was pointed out for wetland research area. In the further, this study could provide the scientific basis for wetland GHG inventory in China.
