Peatland development and carbon dynamics histories of Zoige peatlands for 15000 years

Research Status, Problems and Direction of Soil Organic Carbon in Zoige Peat Wetland

“…Estimation of ground carbon accumulation rate combined with area 0.477 Pg Chen et al, 2014 [14] 1.42 Pg Wang et al, 2014 [22] Estimation of peat reserves by provinces and cities 0.71 Pg (710 Tg) Wang Ming, 2012 [23] Years of data combined with peat volume method were used to estimate 0.63 Pg Liu et al, 2012 [24] Model simulation method EPIC model 0.514 Pg (514 Tg) Ma Kun et al, 2016 [25] HPM model 0.435 Pg Liu Xinwei et al, 2016 [26] Peat decomposition model 1.4 Pg Liu Lijuan et al, 2018 [16] ferences in the estimation of carbon storage in Zoige Peatland, which is mainly due to the uncertainties of soil bulk density, peat depth, peatland area, soil carbon content and peatland carbon accumulation rate [16] . As a result, the estimation of organic carbon storage in peatlands in the same area is quite different, and the data are not comparable.…”

“…Zhou Wenchang et al studied vegetation carbon storage, soil carbon storage and ecosystem carbon storage in peatland under three water level states in Zoige by using the soil profile method and vegetation harvesting method [15] . Liu Lijuan et al reassessed the carbon storage of peatland on the Zoige Plateau based on the area change and carbon accumulation rate of peatland on the Zoige Plateau every thousand years, and used the peat decomposition model and carbon flux reconstruction model to discuss the dynamics of carbon flux in the peatland on the Zoige Plateau over the past 15,000 years [16] . Dong Lijun et al used the method of spatial series instead of time series to study the changes of soil organic carbon content at different degradation stages of alpine meadow in Zoige Wetland and the causes [17] .…”

“…Under natural conditions, peat can accumulate 0.22-1.31 mm per year. The rate of human destruction of peatland is far greater than the rate of peat development, and the protection of peat wetlands is urgent [44] .…”

中国泥炭地土壤碳库估算：方法、进展与展望

“…可见青藏高原泥炭地发育的气 候环境机制还存在争议. 针对碳累积速率, 若尔盖盆地 的研究结果表明泥炭地在早全新世较为温暖时期出现 碳累积的高峰 [18,29,42] (图3(c)). 在近现代气候变暖背景 下, Wang等人 [43] 对若尔盖高原泥炭地的碳累积进行研 究发现, 近50年来的碳累积是整个全新世的1.6倍.…”
