Abstract

The carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O) fluxes measured at a peat extraction site in the Moscow region in different seasons of 2005–2015 are considered. The average daily (taking into account intradaily dynamics) and average annual fluxes (emission factors) of CO₂, CH₄, and N₂O from the interditch spacing (including microscale elevations and depressions) and drainage channels were estimated. The values of CO₂ and N₂O fluxes from the main interditch surface were equal to 3.3 t C-CO₂/(ha year) and 1.1 kg N-N₂O/(ha year), respectively; the value of the CH₄ flux from the channel was 3200 kg CH₄/(ha year). The resulting estimates are consistent with the default emission factors proposed for the “peatland under extraction” land category by the 2013 Supplement to the IPCC 2006 Guidelines for National Greenhouse Gas Inventories: Wetlands. The results can be used for preparing the national report of the Russian Federation on the emission and absorption of greenhouse gases not controlled by the Montreal Protocol.

俄罗斯欧洲部分中部泥炭开采产生的温室气体排放

摘要

考虑了 2005 年至 2015 年不同季节在莫斯科地区的一个泥炭开采点测量的二氧化碳 (CO ₂ )、甲烷 (CH ₄ ) 和一氧化二氮 (N _{2 O) 通量。}估计了来自沟间间距（包括微尺度海拔和洼地）和排水渠的 CO ₂、CH ₄和 N ₂ O 的日均流量（考虑日内动态）和年均流量（排放因子） 。来自主沟表面的CO ₂ 和N ₂ O通量值分别等于3.3 t C-CO ₂ /（ha·年）和1.1 kg NN ₂ O/（ha·年）；CH的值_{来自通道的4} 通量为 3200 kg CH ₄ /（公顷年）。得出的估算值与 IPCC 2006 年国家温室气体清单指南的 2013 年补编：湿地为“开采中的泥炭地”土地类别提出的默认排放因子一致。研究结果可用于编写俄罗斯联邦关于不受《蒙特利尔议定书》控制的温室气体排放和吸收的国家报告。
