Terrestrial ecosystem carbon (C) sequestration plays an important role in ameliorating global climate change. While tropical forests exert a disproportionately large influence on C cycling, there remains open question changes below-ground soil stocks with increases nitrogen (N) deposition, because N supply often does not constrain the growth of forests. We quantified through more than decade continuous addition experiment N-rich primary forest. Results showed that long-term additions...
Abstract Carbon budget accounting relies heavily on Food and Agriculture Organization land-use data reported by governments. Here we develop a new cover-change database for China, finding that differing historical survey methods biased China’s causing large errors in databases. Land ecosystem model simulations driven with the reveal strong carbon sink of 8.9 ± 0.8 Pg from 1980 to 2019 which was not captured data-based estimations due signals. The characterized rapid forest expansion 2019,...
Abstract The impacts of enhanced nitrogen (N) deposition on the global forest carbon (C) sink and other ecosystem services may depend whether N is deposited in reduced (mainly as ammonium) or oxidized forms nitrate) subsequent fate each. However, fates two key reactive their contributions to C sinks are unclear. Here, we analyze results from 13 ecosystem-scale paired 15 N-labelling experiments temperate, subtropical, tropical forests. Results show that total retention similar for ammonium...
Abstract Forest carbon sequestration capacity in China remains uncertain due to underrepresented tree demographic dynamics and overlooked of harvest impacts. In this study, we employ a process-based biogeochemical model make projections by using national forest inventories, covering approximately 415,000 permanent plots, revealing an expansion biomass stock 13.6 ± 1.5 Pg C from 2020 2100, with additional sink through augmentation wood product pool (0.6-2.0 C) spatiotemporal optimization...
Abstract Droughts or floods are usually attributed to precipitation deficits surpluses, both of which may become more frequent and severe under continued global warming. Concurring large-scale droughts in the Southwest flooding Southeast China recent decades have attracted considerable attention, but their causes interrelations not well understood. Here, we examine spatiotemporal changes hydrometeorological variables investigate mechanism underlying contrasting soil dryness/wetness patterns...
Plant diversity has a strong impact on plethora of ecosystem functions and services, especially carbon (C) storage. However, the potential context-dependency biodiversity effects across types, environmental conditions pools remains largely unknown. In this study, we performed meta-analysis by collecting data from 95 biodiversity-ecosystem functioning (BEF) studies 60 sites to explore plant different C pools, including aboveground belowground biomass, soil microbial biomass content types. The...
Abstract Background Forest is the largest biomass carbon (C) pool in China, taking up a substantial amount of atmospheric dioxide. Although it well understood that planted forests (PFs) act as large C sink, contribution human management to storage enhancement remains obscure. Moreover, existing projections forest dynamics suffer from spatially inconsistent age and type information or neglected impacts. In this study, using developed PF maps data collected 1371 plantation sites we simulated...
Ecosystem service has become a hot topic in international ecological research with two major trends of advancing ecosystem mechanism and regional integration methodologies.At the same time,terrestrial is great national science strategic need for restoration,ecological functional regionalization,ecological compensation,and sustaining security.Targeting this necessity frontiers service,this project takes main terrestrial ecosystems China as object research.There are three scientific themes...
Abstract The directionality of the response gross primary productivity (GPP) to climate has been shown vary across globe. This effect hypothesized be result interaction between multiple bioclimatic factors, including environmental energy (i.e. temperature and radiation) water availability. is due tight coupling carbon cycling in plants fact that often drives plant demand. Using GPP data extracted from 188 sites FLUXNET2015 observation-driven terrestrial biosphere models (TBMs), we...
Abstract Together natural growth, afforestation and forest disturbance, such as felling, contribute to the dynamic nature of forests. Thus enhance management, water resource management carbon sequestration, net effect changes on yield must be better understood. Here, we conduct a global meta-analysis 496 watersheds over 25 years investigate impact complexity overall yields. We classify based type human including felling thinning, afforestation, absence external disturbances. find that runoff...
Shifts in forest phenological events serve as strong indicators of climate change. However, the sensitivity phenology to change relation origins has received limited attention. Moreover, it is unknown whether changes with proximity edge. This study examined green-up dates, dormancy time-integrated NDVI (LiNDVI, a measure vegetation productivity growing season), and their sensitivities climatic factors along gradients distance (i.e. proximity) edge (0–2 km) China's natural forests (NF)...
Abstract Background Old-growth forests are irreplaceable with respect to climate change mitigation and have considerable carbon (C) sink potential in soils. However, the relationship between soil organic (SOC) turnover rate forest development is poorly understood, which hinders our ability assess C sequestration capacity of old-growth forests. Methods In this study, we evaluated SOC by calculating isotopic enrichment factor β (defined as slope regression 13 natural abundance log-transformed...
