“…Water content and dry bulk density were obtained from weight loss by drying of a known volume of peat section at 105°C for 12 h. The first one was calculated from the mass difference and the second one was calculated from stable weight and known volume (Martínez Cortizas et al 2009;Bao et al 2010;Sadzawka et al 2006;Wang et al 2004). Ash and organic matter content were determined by calcination at 550°C for 6 h in a muffle furnace (Martínez Cortizas et al 2009;Bao et al 2010;Sadzawka et al 2006;Wang et al 2004).…”

“…In Europe, North America, and China there have been conducted numerous studies on recent carbon dynamics in peatland (Gorham 1991;Turunen et al 2004;Tolonen and Turunen 1996;Pitkänen et al 1999;Bao et al 2010;Ali et al 2008;Pontevedra Pombal et al 2004). Nevertheless, similar studies are scarce in southern South America.…”

“…The rate of C sequestration in peatlands is a crucial element in understanding the global C cycle and has been estimated on different timescales to ascertain the role of peatlands in global warming in the context of rising atmospheric CO 2 (Bao et al 2010;Joosten and Clarke 2002). Added to this is that a better management of ecosystem carbon stocks and fluxes can substantially contribute to reducing atmospheric greenhouse gas concentrations (Joosten 2011).…”

Background: Peatlands play a key role in the global carbon cycle; these contain one third of the world's soil organic carbon, equivalent to more than half the amount of carbon in the atmosphere. Nevertheless, these ecosystems have been scarcely studied in southern South America. The main objective of this paper is to evaluate the recent accumulation rates of carbon (C) and nitrogen (N) in two kinds of oligotrofic peatlands in Isla Grande de Chiloé (Chile). Results: Using peat C and N content, dry bulk density, and Pb-210 dating, we determined the rates of N and C accumulation in profiles from five peatlands in the northern Chilean Patagonia. The recent rate of C accumulation (RERCA) ranges from 8.5 to 87.06 g C m −2 year −1 , and the recent rate of N accumulation (RERNA) ranges from 0.15 to 2.37 g N m −2 year −1 . The difference in RERCA and RERNA between glacial peatlands and anthropogenic peatlands was significant. One of the remarkable results is that accumulation of N and C are directly related. Conclusions: This study contributes for a better understanding of the Patagonian peatlands of Chile. In addition, this research contributes by setting a basis for conducting further studies and for assessing the impacts of climate change on peatlands.

“…So far much work about peatlands in China was focused on the formation and distribution patterns, mainly for the usage of peat resources (Chai, 1981;Ma et al, 1987). With ubiquitous warming and intensified anthropogenic activities, many studies tried to determine the peat carbon density and peat carbon storage (Wang, 2009;Wang et al, 2012;Liu et al, 2012b), and the accumulation rate of peat and carbon (Sun et al, 2001;Bao et al, 2010). They also tried to identify the influencing factors for peat accumulation (Large et al, 2009;Gao et al, 2010;Zhou et al, 2010).…”

“…Peatland is an important ecosystem of the Changbai Mountains, and many studies have been conducted on the assessment of the vulnerability of this ecosystem and environmental changes (Jiang et al, 2008;Hong et al, 2009;Bao et al, 2010). However, the studies related to atmospheric dust are still insufficient due to the poor understanding of the sedimentological character of the peat sequence.…”

Abstract:The grain-size distribution characteristics and grain-size parameters of sediment in two vertical sections of Daniugou peatland in the Changbai Mountains were systematically investigated. A comparative analysis of the sediment granularity using a discriminative function with Hongyuan peat, red clay, loess-paleosol, fluvial deposit as well as lacustrine deposit was also conducted. It turns out that the vertical section of Daniugou peat ash is primarily constituted by clay and silt particles, and the content of sand is relatively small. Grain-size frequency curves generally show a single-peak modality while a bimodal pattern is detected in the upper layer. The grain-size component and peak pattern of grain-size frequency curves also illustrate that peat ash materials were transported to the peatland by long-range aeolian dust during the deposition process, while there existed short-distance dust influence in peat deposition of the upper layer. Comparisons of grain-size parameters and the discriminative Y-value of Daniugou peat ash with those of typical aeolian sediments show close similarities, suggesting the possibility that atmospheric dust transport processes were involved in the accumulation of peat again. Moreover, the variations of grain-size distribution suggest the local environmental deterioration which is just the driving force of local dust elevation. Grain-size analysis of peatland sediment is demonstrated to be one effective method to extract information about regional and global environmental evolution, and more attention should be paid to current local ecological environment and to seeking a balance between economic development and environmental protection in Northeast China.
