Significance Previous estimations of carbon budgets in China’s terrestrial ecosystems varied greatly because the multiplicity data sources and inconsistency methodologies. By conducting a methodologically consistent field campaign across country, we estimated that total pool forests, shrublands, grasslands, croplands was 79.24 ± 2.42 Pg C. The density exhibited strong dependence on climate regime: it decreased with temperature but increased precipitation. country’s forests have large...
Old-growth forests have traditionally been considered negligible as carbon sinks because uptake has thought to be balanced by respiration. We show that the top 20-centimeter soil layer in preserved old-growth southern China accumulated atmospheric at an unexpectedly high average rate of 0.61 megagrams hectare-1 year-1 from 1979 2003. This study suggests cycle processes belowground system these are changing response environment. The result directly challenges prevailing belief ecosystem...
Abstract Understanding the dynamics and underlying mechanism of carbon exchange between terrestrial ecosystems atmosphere is one key issues in global change research. In this study, we quantified fluxes different China, analyzed their spatial variation environmental drivers based on long‐term observation data China FLUX sites published from other flux China. The results indicate that gross ecosystem productivity ( GEP ), respiration ER net NEP ) showed a significantly latitudinal pattern,...
• Carbon (C) and water cycles of terrestrial ecosystems are two coupled ecological processes controlled partly by stomatal behavior. Water-use efficiency (WUE) reflects the coupling relationship to some extent. At stand ecosystem levels, variability WUE results from trade-off between loss C gain in process plant photosynthetic assimilation. Continuous observations C, water, energy fluxes were made at three selected forest sites ChinaFLUX with eddy covariance systems 2003 2005. different...
Abstract Responses of hydrological processes to climate change are key components in the I ntergovernmental P anel for C limate hange ( IPCC ) assessment. Understanding these responses is critical developing appropriate mitigation and adaptation strategies sustainable water resources management protection public safety. However, not well understood little long‐term evidence exists. Herein, we show how change, specifically increased air temperature storm intensity, can affect soil moisture...
Recent studies have suggested that tropical forests may not be resilient against climate change in the long term, primarily owing to predicted reductions rainfall and forest productivity, increased tree mortality, declining biomass carbon sinks. These changes will caused by drought-induced water stress ecosystem disturbances. Several recent reported has mortality temperate boreal forests, or both recruitment rates forests. However, no study yet examined these subtropical account for majority...
Abstract Net ecosystem productivity (NEP) was continuously measured using the eddy covariance (EC) technique from 2003 to 2005 at three forest sites of ChinaFLUX. The forests include Changbaishan temperate mixed (CBS), Qianyanzhou subtropical coniferous plantation (QYZ), and Dinghushan evergreen broad‐leaved (DHS). They span wide ranges temperature precipitation are influenced by eastern Asian monsoon climate varying extent. In this study, we estimated respiration (RE) gross (GEP)....
Abstract Soil organic carbon (SOC) plays critical roles in stabilizing atmospheric CO2 concentration, but the mechanistic controls on amount and distribution of SOC global scales are not well understood. In turn, this has hampered ability to model C budgets find measures mitigate climate change. Here, based data from a large field survey campaign with 2600 plots across China's forest ecosystems collection published forested land, we that low litter carbon-to-nitrogen ratio (C/N) high wetness...
Abstract Light use efficiency (LUE) models are widely used to simulate gross primary production (GPP). However, the treatment of plant canopy as a big leaf by these can introduce large uncertainties in simulated GPP. Recently, two‐leaf light (TL‐LUE) model was developed GPP separately for sunlit and shaded leaves has been shown outperform big‐leaf MOD17 at six FLUX sites China. In this study we investigated performance TL‐LUE wider range biomes. For optimized parameters tested using data...
There is evidence that climate change induced tree mortalities in boreal and temperate forests increased forest turnover rates (both mortality recruitment rates) Amazon forests. However, no study has examined China's tropical subtropical evergreen broadleaved (TEBF) cover >26% of terrestrial land. The sustainability this biome vital to the maintenance local ecosystem services (e.g., carbon sequestration, biodiversity conservation, climatic regulation), many which may influence patterns...
Climate models simulating continental scale deforestation suggest a warming effect of land clearing on the surface air temperature in tropical zone and cooling boreal due to different control biogeochemical biophysical processes. Ongoing land-use/cover changes mostly occur at local scales (hectares), it is not clear whether local-scale will generate patterns consistent with climate model results. Here we paired 40 12 flux sites nearby weather stations North South America Eastern Asia,...
Abstract Intensification of the Earth's hydrological cycle amplifies interannual variability precipitation, which will significantly impact terrestrial carbon (C) cycle. However, it is still unknown whether previously observed relationship between soil respiration ( R s ) and precipitation remains applicable under extreme change. By analyzing observations from a much larger dataset field experiments (248 published papers including 151 grassland studies 97 forest studies) across wider range...
Over the past 2 to 3 decades, Chinese forests are estimated act as a large carbon sink, yet magnitude and spatial patterns of this sink differ considerably among studies. Using microwave (L- X-band vegetation optical depth [VOD]) (normalized difference index, leaf area tree cover) remote-sensing products, study compared live woody aboveground biomass (AGC) dynamics over China between 2013 2019. Our results showed that cover has highest consistency with published AGC maps (mean correlation...
