“…However, influence of management measures on carbon sequestration potentials should not be underestimated (Nabuurs et al., 2000). Considering hydrothermal condition influencing carbon balances of natural forests, plantations are a type of ecosystems under human control, and their operations and managements are more important factors that affecting their carbon balances (Jandl, Neumann, & Eckmullner, 2007; Jandl, Lindner, et al., 2007; Waterworth & Richards, 2008).

The Grain for Green Program (GGP) was the most all‐embracing program of ecological reconstruction implemented in China. To estimate carbon storages and carbon sequestration potentials of the GGP forests, the study presented in the paper collected data spanning from 1999 to 2010, such as tree species, tree planting area relevant to the GGP, empirical growth curves suitable for different planted tree species in China, as well as wood density (WD), biomass expansion factor (BEF), carbon fraction (CF) of different trees species, and estimated the carbon storages of the biomasses of GGP forests from 1999 to 2050. It showed that the total carbon storage of the biomass of GGP forests was 320.29 Tg upon the GGP completion in 2010; the total carbon sequestration is higher during the early GGP‐implementation stage than at the late GGP‐implementation stage, and the annual mean carbon sequestration of GGP forests was 26.69 Tg/year. The potential of GGP forests as carbon sink presented an increasing increment. In China, the potential increments of GGP forests as carbon sinks were estimated to be 397.34, 604.00, 725.53, and 808.90 Tg in 2020, 2030, 2040, and 2050, respectively, and the carbon sequestration rates were 1.72, 0.89, 0.52, and 0.36 Mg ha−1 year−1, respectively, corresponding to 2010s, 2020s, 2030s, and 2040s. Therefore, the GGP forests had bigger carbon sequestration capacities and potentials in China.

“…Estimates of F LUC are calculated using the Australian National Carbon Accounting System (NCAS), a greenhouse accounting framework for the land sector. It is based on spatially explicit ecosystem modelling that uses extensive groundbased datasets for parameterization and validation, and Landsat data time series at 25-m resolution (Richards and Brack, 2004;Waterworth and Richards, 2008;Waterworth et al, 2007).…”

Abstract. This paper reports a study of the full carbon (C-CO2) budget of the Australian continent, focussing on 1990–2011 in the context of estimates over two centuries. The work is a contribution to the RECCAP (REgional Carbon Cycle Assessment and Processes) project, as one of numerous regional studies. In constructing the budget, we estimate the following component carbon fluxes: net primary production (NPP); net ecosystem production (NEP); fire; land use change (LUC); riverine export; dust export; harvest (wood, crop and livestock) and fossil fuel emissions (both territorial and non-territorial). Major biospheric fluxes were derived using BIOS2 (Haverd et al., 2012), a fine-spatial-resolution (0.05°) offline modelling environment in which predictions of CABLE (Wang et al., 2011), a sophisticated land surface model with carbon cycle, are constrained by multiple observation types. The mean NEP reveals that climate variability and rising CO2 contributed 12 &pm; 24 (1σ error on mean) and 68 &pm; 15 TgC yr−1, respectively. However these gains were partially offset by fire and LUC (along with other minor fluxes), which caused net losses of 26 &pm; 4 TgC yr−1 and 18 &pm; 7 TgC yr−1, respectively. The resultant net biome production (NBP) is 36 &pm; 29 TgC yr−1, in which the largest contributions to uncertainty are NEP, fire and LUC. This NBP offset fossil fuel emissions (95 &pm; 6 TgC yr−1) by 38 &pm; 30%. The interannual variability (IAV) in the Australian carbon budget exceeds Australia's total carbon emissions by fossil fuel combustion and is dominated by IAV in NEP. Territorial fossil fuel emissions are significantly smaller than the rapidly growing fossil fuel exports: in 2009–2010, Australia exported 2.5 times more carbon in fossil fuels than it emitted by burning fossil fuels.

“…In the local Taihang Mountian area, the typical forest management practices of R. pseudoacacia, P. granatum, and Z. jujube are given in Table 2. Forest management of plantation has an obvious effect on GHG emissions by changing soil hydrothermal condition, soil nutrient content, and soil structure (Waterworth and Richards, 2008). Haynes and Gower (1995) showed that the addition of mineral fertilizer (N, P, K, Ca, Mg, S) induced a decrease in soil respiration and fine root production of a coniferous forest soil.…”

Abstract. The objectives of this study were to investigate seasonal variation of greenhouse gas fluxes from soils on sites dominated by plantation (Robinia pseudoacacia, Punica granatum, and Ziziphus jujube) and natural regenerated forests (Vitex negundo var. heterophylla, Leptodermis oblonga, and Bothriochloa ischcemum), and to identify how tree species, litter exclusion, and soil properties (soil temperature, soil moisture, soil organic carbon, total N, soil bulk density, and soil pH) explained the temporal and spatial variation in soil greenhouse gas fluxes. Fluxes of greenhouse gases were measured using static chamber and gas chromatography techniques. Six static chambers were randomly installed in each tree species. Three chambers were randomly designated to measure the impacts of surface litter exclusion, and the remaining three were used as a control. Field measurements were conducted biweekly from May 2010 to April 2012. Soil CO 2 emissions from all tree species were significantly affected by soil temperature, soil moisture, and their interaction. Driven by the seasonality of temperature and precipitation, soil CO 2 emissions demonstrated a clear seasonal pattern, with fluxes significantly higher during the rainy season than during the dry season. Soil CH 4 and N 2 O fluxes were not significantly correlated with soil temperature, soil moisture, or their interaction, and no significant seasonal differences were detected. Soil organic carbon and total N were significantly positively correlated with CO 2 and N 2 O fluxes. Soil bulk density was significantly negatively correlated with CO 2 and N 2 O fluxes. Soil pH was not correlated with CO 2 and N 2 O emissions. Soil CH 4 fluxes did not display pronounced dependency on soil organic carbon, total N, soil bulk density, and soil pH. Removal of surface litter significantly decreased in CO 2 emissions and CH 4 uptakes. Soils in six tree species acted as sinks for atmospheric CH 4 . With the exception of Ziziphus jujube, soils in all tree species acted as sinks for atmospheric N 2 O. Tree species had a significant effect on CO 2 and N 2 O releases but not on CH 4 uptake. The lower net global warming potential in natural regenerated vegetation suggested that natural regenerated vegetation were more desirable plant species in reducing global warming.
