“…Estimates of national and global terrestrial SOC stock vary greatly (Mitra et al 2005). For example, the SOC stock in China's wetlands has previously been estimated to be somewhere between 3.7 and 12.2 Pg C (Yu et al 2007, Niu et al 2009, Zheng et al 2013. Our study indicates that the SOC stock in China's PWs is 4.3±1.4 Pg C. This is the first such estimate for PWs alone.…”

“…A database consisting of 4996 samples across 297 sites from 73 individual literature sources was created (table S2). In order for these data to be comparable with other global and national SOC stock estimates (Sjörs 1980, Mitra et al 2005 and Chinese wetland or peatland SOC stocks (Wang et al 2003, Zheng et al 2013, we gathered data from the upper 1 m of the soil profile, divided into two layers, topsoil (0-30 cm) and subsoil (30-100 cm). For the TH zone, we used data from the Harmonized World Soil Database (HWSD) because no other suitable data were available in the literature.…”

“…On a national scale, based on the Chinese wetland RS map and the 1:1million soil map, Zheng et al (2013) Chinese peatlands was 143.8 kg C m −2 . There is clearly considerable variability in SOC density between wetland types.…”

“…The lack of spatially explicit wetland area databases combined with a lack of representative in situ data on SOC is a major constraint for accurate estimation of SOC storage in China's wetlands. Thus previous estimates of wetland SOC storage in China are highly uncertain (Wang et al 2003, Mitra et al 2005, Wang 2009, Zheng et al 2013. Many of the earlier SOC studies have predominantly focused on the Northeast of China (NEC), Zoige plateau and the middle and lower reaches of the Yangtze River, and do not provide a representative estimate of country-wide SOC stocks.…”

Palustrine wetlands (PWs) include all bogs, fens, swamps and marshes that are non-saline and which are not lakes or rivers. They therefore form a highly important group of wetlands which hold large carbon stocks. If these wetlands are not protected properly they could become a net carbon source in the future. Compilation of spatially explicit wetland databases, national inventory data and in situ measurement of soil organic carbon (SOC) could be useful to better quantify SOC and formulate long-term strategies for mitigating global climate change. In this study, a synergistic mapping approach was used to create a hybrid map for PWs for China and to estimate their SOC content. Total SOC storage in PWs was estimated to be 4.3±1.4 Pg C, with a SOC density of 31.17 (±10.55) kg C m −2 in the upper 1 m of the soil layer. This carbon stock is concentrated in Northeast China (49%) and the Qinghai-Tibet Plateau (41%). Given the large pool of carbon stored in PWs compared to other soil types, we suggest that urgent monitoring programmes on SOC should be established in regions with very few datasets, but where PWs appear to be common such as the Tibet region and Northwest China.

“…Another interesting topic in conservative biology is the effect of climate changes on protected animals, especially on bird distribution and migration in China [80,81], which depends largely on the development of remote sensing technology. Prof. Peng Gong's laboratory at Tsinghua University and Chinese Academy of Sciences published a series of papers to introduce the application of satellite remote sensing in the protection of national wetland reserves and greenes in China [82][83][84][85]. These researches represent a key frontier advancement of current conservative biology.…”

Simulating potential impacts of climate changes on distribution pattern and carbon storage function of high‐latitude wetland plant communities in the Xing'anling Mountains, China

Though one of the most vulnerable terrestrial ecosystems, wetlands provide multiple ecosystem services, most notably storing carbon. It is now widely recognized that climate change could have a large impact on high-latitude wetlands. A key question is how climate change will affect the distribution pattern of wetland plant communities, and to what extent the transitions among different wetland plant communities respond to regional warming? To answer this question, we estimated the total SOC storage with 139 soil profiles in the Xing'anling Mountains and performed ensemble species distribution modelling for 11 dominant wetland plant communities by using numerous vegetation plots. Results show that 4.5-23.8% of the high-latitude wetlands in the study area would be lost following widespread thawing of permafrost under different climate warming scenarios by the end of this century. The total wetland SOC in the Xing'anling Mountains is estimated to be 1.58 Pg, about 25.5-29.3% of the total of China's wetlands, however, predicted wetland loss could put 5.4-20.5% (0.08-0.32 Pg C) of the total SOC storage at risk of instability. Our results also predicted a significant northward migration of southern Deyeuxia angustifolia communities driven by future climate changes. This wetland succession could profoundly reduce future carbon sequestration capacity of wetlands in the study area. The findings presented here are helpful for both current reserve management and future conservation planning of wetlands in the study area.
