Abstract Aims Soil dissolved organic carbon (DOC) is a primary form of labile in terrestrial ecosystems, and therefore plays vital role soil cycling. This study aims to quantify the budgets DOC at biome global levels examine variations their environmental controls. Location Global. Time period 1981–2019. Methods We compiled dataset analysed concentration distribution across 10 biomes. Results Large are found among biomes space declines exponentially along depths. Tundra has highest 0–30 cm...
Abstract Mounting evidence supports that wetland ecosystems, one of the largest carbon pools on earth, are exposed to ample nitrogen (N) additions due atmospheric deposition or N loading from upstream agricultural fertilizer application. However, our understanding how enrichment affects fluxes greenhouse gases (GHGs) in wetlands is weak. A 5 year addition experiment was conducted examine responses CH 4 and 2 O as well ecosystem respiration Sanjiang Plain, Northeast China, through 2005 2009....
Wetlands regulate the balance of global organic carbon. Small changes in carbon stocks wetland ecosystem play a crucial role regional soil cycle. However, an accurate estimation is still be debated for China’s wetlands due to limitation data collection and methodology. Here, we investigate (SOC) storage 1-m depth palustrine wetlands. A total 1383 sample were collected from China. The sources are divided into three parts, respectively, published literature, books, actual measurement points....
Permafrost soils act as large sinks of organic carbon but are highly sensitive to interference such changes in land use, which can greatly influence dissolved loads streams.
The North China Plain is an important grain production area in China. Due to the low content of soil organic carbon, increasing application rate nitrogen fertilizer would not lead a continuous increase maize yield at present. combined and inorganic widely regarded as measure simultaneously carbon; however, effect on N2O emissions from farmland unclear. Here, crop yields cropland under different types rates fertilizers plus N were measured Plain. field experiment included eight treatments:no...
Climate change is accelerating its impact on northern ecosystems. Northern peatlands store a considerable amount of C, but their response to climate remains highly uncertain. In order explore the feedback peatland in Great Hing’an Mountains future change, we simulated overall net ecosystem exchange (NEE), respiration (ER), and gross primary production (GPP) during 2020–2100 under three representative concentration pathways (RCP2.6, RCP6.0, RCP8.5). Under RCP2.6 RCP6.0 scenarios, carbon sink...
Abstract. As an important dissolved organic carbon (DOC) reservoir, the mires in Sanjiang Plain, Northeast China, have been suffering from large scale of reclamation, and thus elevated loss degradation since 1960s. This study compares export dynamics carbons, as well chemical characteristics DOC, natural mire, degraded mire drainage ditches during growing seasons 2008 to 2010 with aim clarify final effects longterm reclamation on carbons. Results show that average concentrations total (TC)...
Surface soil samples (0∼20cm) were collected from a Calamagrostis angustifolia freshwater marsh in the Sanjiang Plain May to September and active organic carbon including microbial biomass (MBC), easily oxidizable (EOC), dissolved (DOC) analyzed aiming reveal their seasonal dynamics characterisitics correlationships with activities of invertase, amylase cellulase. The results indicated that MBC, EOC DOC varied significantly season variation coefficients 42.1%, 16.6%, 7.7% respectively. MBC...

As an important nutrient reservoir, the mires in Sanjiang Plain of Northeast China have been suffering from large-scale agriculture reclamation since 1960s. The effects long-term on dynamics dissolved nutrients fluvial systems are revealed through surveying export concentrations nitrogen and phosphorus natural mire, degraded mire drainage ditches during growing seasons 2009 2010. results show that mean total (TDN, 2.03 ± 0.355 mg l−1) much higher than (1.15 0.247 (1.03 0.231 l−1), fraction...
