: Although litter can regulate the global climate by influencing soil N2O fluxes, there is no consensus on the major drivers or their relative importance and how these impact at the global scale. In this paper, we conducted a meta-analysis of 21 global studies to quantify the impact of litter removal and litter doubling on soil N2O fluxes from fore...
Article
Carbon (C) and nitrogen (N) coupling processes in terrestrial ecosystems have the potential to modify the sensitivity of the global C cycle to climate change. But the degree to which C–N interactions contribute to the sequestration of terrestrial ecosystem C (Cseq), both now and in the future, remains uncertain. Methods In this study we used a met...

Heatwaves exert disproportionately strong and sometimes irreversible impacts on forest ecosystems. These impacts remain poorly understood at the tree and species level and across large spatial scales. Here, we investigate the effects of the record-breaking 2018 European heatwave on tree growth and tree water status using a collection of high-tempor...

Full-text available
Soil respiration is controlled by land‐use changes associated with cropland vegetation restoration, and this can vary with topography, although the magnitude of this effect and the underlying mechanisms are still unclear. We synthesized 69 recently published papers from China to explore the influence of topography‐related changes in land use on soi...

Salix matsudana is an important tree species for shelterbelt and barren hill afforestation in North China. Knowledge of the seasonal pattern of the stem radial growth (SRG) of S. matsudana and its response to environmental factors is crucial for understanding the tree growth and climate relationships in the increasingly warm and dry climate of Nort...
Article
Full-text available
The importance of labile soil carbon (C) and nitrogen (N) in soil biogeochemical processes is now well recognized. However, the quantification of labile soil C and N in soils and the assessment of their contribution to ecosystem C and N budgets is often constrained by limited information on spatial variability. To address this, we examined spatial...
Article
Full-text available
Forest ecosystems play an important role in regulating global temperatures through their capability to take up and store CO2 from the atmosphere, but the magnitude and sustainability of this carbon (C) sink is critically dependent on the availability of nutrients, particularly nitrogen (N). However, the extent to which the absolute amount of N or m...
Article
Full-text available
Globally, soils store two to three times as much carbon as currently resides in the atmosphere, and it is critical to understand how soil greenhouse gas (GHG) emissions and uptake will respond to ongoing climate change. In particular, the soil-toatmosphere CO2 flux, commonly though imprecisely termed soil respiration (RS), is one of the largest car...
Article
Full-text available
Litter inputs can influence soil respiration directly through labile C availability and, indirectly, through the activity of soil microorganisms and modifications in soil micro-climate; however, their relative contributions and the magnitude of any effect remain poorly understood. We synthesized 66 recently published papers on forest ecosystems usi...
Article
Full-text available
Soil fluxes of nitrous oxide (N 2 O) play an important role in the global greenhouse gas budget. However, the response of soil N 2 O emissions to climate change in temperate forest plantations is not yet well understood. In this study, we assessed the responses of soil N 2 O fluxes to experimental warming with or without water addition, using a rep...

Surface litter(hereafter ‘litter’) input was an important factor affecting soil respiration. However, based on the current study results at home and abroad,the factors to influence the response of soil respiration to litter input were still unclear. 1 393 pairs of valid data from 30 published research papers were used for analyzing the effect of li...
Article
Interactions between the carbon (C) and nitrogen (N) cycles can impact on the sensitivity of terrestrial C storage to elevated atmospheric carbon dioxide (CO2) concentrations (eCO2). However, the underlying mechanisms associated with CN interactions that influence terrestrial ecosystem C sequestration (Cseq) remains unclear. Here, we quantitatively...
Article
Future climate change is expected to alter the terrestrial carbon cycle through its impact on soil respiration. In this study, we determined the responses of soil respiration and its components to experimental warming with or without water addition. A replicated in situ heating (∼2 °C above ambient soil temperatures) and water addition (170 mm in t...
Article
Land-use conversions and elevated temperature can impact on carbon dioxide (CO2) and nitrous oxide (N2O) emissions, both of which are important greenhouse gasses (GHGs). Afforestation activity has increased significantly over the last century with a significant focus in recent years directed at offsetting GHG emissions, as forests have a large capa...

Thesis
Projected changes in climate, including increases in soil temperature and changes in precipitation regimes that result in less frequent, but more intense rainfall events may result in modifications in greenhouse gas (GHG) emissions from terrestrial ecosystems. This investigation assessed the impacts of artificial warming, using infra-red heaters, w...
Conference Paper
Dendrometers have proven useful to understand water fluxes and storage in tree stems as well as growth dynamics. To date, dendrometer data have been primarily employed at the site level with little attention given to large-scale links among climate, stress, and growing season characteristics. Within the framework of the COST Action STReESS (FP 1106...

Abstract:The change of soil organic carbon (SOC) pool in cropland ecosystem and its effecting factors were little investigated in the alpine area of Qinghai Province in recent decades. Using soil type as the unit, combining the second soil survey data (1982) and the recent (2011) repeatedly collected soil samplings, the spatio-temporal distribution...

A Soil-Plant Analysis Development (SPAD) chlorophyll meter can be used as a simple tool for evaluating N concentration of the leaf and investigating the combined effects of nitrogen rate and leaf age on N distribution. We conducted experiments in a paddy field over two consecutive years (2008-2009) using rice plants treated with six different N app...

Located in the arid and semi-arid areas, Loess Plateau has fragile ecosystems, serious soil erosion and severe loss of soil organic carbon pool. Vegetation recovery become an important way to control soil erosion and improve soil organic carbon reserves. As an important biotic factor, vegetation affect the amount of soil organic matter inputs; and...

Aboveground litter is a key factor for carbon sequestration in territorial ecosystems as well as soil conservation in erosion-derived, degraded areas. On the Loess Plateau, understanding aboveground litter contribution to soil respiration (LC) enhances the investigation of soil C dynamics as a consequence of litter accumulation accompanying vegetat...

The spatial distribution patterns of soil water and Soil Organic Carbon(SOC) caused by topography and land use provide opportunities to study the coupling of water and carbon of the terrestrial ecosystem. It can help us better understand the contribution of soil water to SOC accumulation and distribution at a watershed scale, but the strong variabi...

Slope aspect and position are two important factors which affect the changes of soil organic carbon (SOC) and total nitrogen (TN). It is important for studying the influences of two terrain factors on the SOC and TN and forecasting the changes of carbon sink in watersheds of the Loess Plateau. Based on two slope aspects (west-facing slope and east-...

On the loess plateau, summer fallow season is a hot rainy time with intensive soil microbe activities. To evaluate the response of soil respiration to soil moisture, temperature, and N fertilization during this period is helpful for a deep understanding about the temporal and spatial variability of soil respiration and its impact factors, then a fi...
