“…The carbon storage of herbs was only measured in six-year-old plantations, which showed that MX accumulated significantly more carbon than monoculture plantations, EU, AC or CH. We found that the contribution of the sum of shrubs and herbs to total carbon storage of AC and MX was 18.7% and 46.6%, which was greater than that reported in other studies [33,34]. The greater contribution of understory vegetation to total carbon storage was mainly attributed to higher resource availability, such as light under younger plantations.…”

Abstract:In order to understand how carbon storage and allocation patterns vary among plantation types, we estimated carbon allocation between above-and below-ground compartments in four subtropical plantations and a naturally recovered shrubland (as a control). Results indicated that the carbon storage and allocation pattern varied greatly among forest types and was highly dependent on specific traits of trees and understory vegetation. The fast-growing species, such as Eucalyptus urophylla, accumulated more carbon in plant biomass. The biomass carbon was about 1.9-and 2.2-times greater than the 10-species mixed plantation and Castanopsis hystrix plantations, respectively. Meanwhile, the plantations sequestered 1.5-to 3-times more carbon in biomass than naturally recovered shrubland. The carbon allocation pattern between above-and below-ground compartments also varied with plantation type and stand age. The ratio of tree root carbon to tree aboveground carbon decreased with stand age for Eucalyptus urophylla and the 10-species mixed plantation. In contrast, the ratio increased for Acacia crassicarpa. Our data suggested that planting the fast-growing species in the degraded land of subtropical China was an effective choice in terms of carbon sequestration. The information about OPEN ACCESSForests 2015, 6 795 carbon allocation patterns was also valuable for decision making in sustainable forest management and climate change mitigation.

“…The method for carbon accumulation rate was adopted as follows (Zhou et al., 2008):

Cr = \frac{C t k - C t j}{t_{k - j}}, false(k > j false)

where Cr represents carbon accumulation rate (Mg ha −1 year −1 ); C tk , and C tj are carbon storage in year k and j (Mg); t k ‐ j is the interval of time between years k and j . In our study, the Cr in the periods of 2010–2020, 2020–2030, 2030–2040, and 2040–2050 was the mean values of the 10 years of each period.…”

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.

“…A 10-year, large-scale reforestation program was implemented to counter ecosystem degradation as a result of human disturbances in Guangdong province in South China (Zhou et al 2008). Reforestation not only contributed to the erosion control but also led to large C sequestration in vegetation and soils in Guangdong province from 1980 to 2000 (Xie et al 2007;Zhou et al 2008).…”

Background aim and scope Soil organic carbon (SOC) accumulation is strongly affected by soil erosion and deposition that differ at slope positions of a watershed. However, studies on the effects of topography on soil aggregation and SOC dynamics, especially after the implementation of vegetation restoration, are rare. Poorly understood mechanisms and a lack of quantification for the suite of ecological benefits brought by the impacts of topography after planting further obstructed our understanding of terrestrial ecosystem carbon (C) sequestration. The purposes of this study are to (1) quantify the impacts of vegetation restoration on size and stability of soil aggregates and the sequestration of C in soil and (2) to address the impacts of various slope locations on aggregates and SOC distribution. Materials and methodsThe experimental sites were set up in 1959 on a highly disturbed barren land in a tropical and coastal area of Guangdong province in South China. One site received human-induced vegetation restoration (the restored site), while the other received no planting and has remained as barren land (the barren site). The soil in the study sites was a latosol developed from granite. Soil samples were taken from 0 to 20 and 20 to 40 cm soil layer at shoulder and toe slope positions at both sites for comparisons. Soils were analyzed for proportion of soil macroaggregates (>0.25 mm), the SOC in soil layers, and the aggregate soil organic carbon (AOC) at different aggregate sizes. Results and discussion Measurements in 2007 showed that fractions of water stable macroaggregates in 0-40 cm at shoulder and toe slope ranged from 28% to 45%, about one third to one half of those of dry macroaggregates (91-95%) at the restored site. Soil macroaggregates were not detected at barren site in 2007. Average SOC storage in 0-40 cm soil layer of shoulder and toe slope positions at the restored site was 56.5±10.9 Mg C ha −1 , about 2.4 times of that (23.4± 4.6 Mg C ha −1 ) at barren site in 2007. Since 1959, the soil aggregation and SOC storage are significantly improved at the restored site; opposite to that, soil physical and chemical quality has remained low on the barren land without planting. SOC storage in 0-40 cm at toe slope was 15.9± 1.8 Mg C ha −1 , which is only half of that (30.9±9 Mg C ha −1 ) at shoulder slope of the barren site; this is opposite to the pattern found at restored site. The ratios of AOC in 0-20 cm to AOC in 20-40 cm at toe slope were lower than those at shoulder slope of the restored site. The comparison of organic carbon sequestered in soils at different slope positions suggest that soil aggregates played a role in sequestering C based upon landscape positions and soil profile depth as a consequence of soil erosion and deposition.
