Spatial and temporal variations of net ecosystem productivity in Xinjiang Autonomous Region, China based on remote sensing

open access: yesFrontiers in Plant Science, 2023
Net ecosystem productivity (NEP), which plays a key role in the carbon cycle, is an important indicator of the ecosystem's carbon budget. In this paper, the spatial and temporal variations of NEP over Xinjiang Autonomous Region, China from 2001 to 2020 ...

Asymmetric warming significantly affects net primary production, but not ecosystem carbon balances of forest and grassland ecosystems in northern China [PDF]

open access: yes, 2015
We combine the process-based ecosystem model (Biome-BGC) with climate change-scenarios based on both RegCM3 model outputs and historic observed trends to quantify differential effects of symmetric and asymmetric warming on ecosystem net primary ...

Impacts of droughts on carbon sequestration by China's terrestrial ecosystems from 2000 to 2011 [PDF]

open access: yesBiogeosciences, 2014
In recent years, China's terrestrial ecosystems have experienced frequent droughts. How these droughts have affected carbon sequestration by the terrestrial ecosystems is still unclear.

Impact of Atmospheric Optical Properties on Net Ecosystem Productivity of Peatland in Poland

open access: yesRemote Sensing, 2021
Peatlands play an important role in the global carbon cycle due to the high carbon storage in the substrate. Ecosystem production depends, for example, on the solar energy amount that reaches the vegetation, however the diffuse component of this flux can

Effects of climate change and land use/cover changes on carbon sequestration in forest ecosystems in the coastal area of China

open access: yesFrontiers in Forests and Global Change, 2023
IntroductionClimate change and land use/cover changes (LUCC) greatly influenced terrestrial carbon sequestration.MethodsThis study evaluated the effects of climate change and LUCC on the carbon sequestration of forest ecosystems from 1991 to 2020 in the ...

Influence of Spring and Autumn Phenological Transitions on Forest Ecosystem Productivity [PDF]

open access: yes, 2010
We use eddy covariance measurements of net ecosystem productivity (NEP) from 21 FLUXNET sites (153 site-years of data) to investigate relationships between phenology and productivity (in terms of both NEP and gross ecosystem photosynthesis, GEP) in ...

Analyzing the causes and spatial pattern of the European 2003 carbon flux anomaly in Europe using seven models [PDF]

open access: yes, 2007
International audienceGlobally, the year 2003 is associated with one of the largest atmospheric CO2 rises on record. In the same year, Europe experienced an anomalously strong flux of CO2 from the land to the atmosphere associated with an exceptionally ...

Net ecosystem productivity and its uncertainty in a diverse boreal peatland [PDF]

open access: yes, 1999
Net ecosystem exchange (NEE) of CO2 was measured in four peatlands along plant community, hydrologic, and water chemistry gradients from bog to rich fen in a diverse peatland complex near Thompson, Manitoba, as part of the Boreal Ecosystem-Atmosphere ...

Comparison of boreal ecosystem model sensitivity to variability in climate and forest site parameters [PDF]

open access: yes, 2001
Ecosystem models are useful tools for evaluating environmental controls on carbon and water cycles under past or future conditions. In this paper we compare annual carbon and water fluxes from nine boreal spruce forest ecosystem models in a series of ...

Boreal forest CO2 exchange and evapotranspiration predicted by nine ecosystem process models: Intermodel comparisons and relationships to field measurements [PDF]

open access: yes, 2001
Nine ecosystem process models were used to predict CO2 and water vapor exchanges by a 150-year-old black spruce forest in central Canada during 1994–1996 to evaluate and improve the models.
