Аннотация: Afforestation in low-carbon-density areas has been proposed for mitigating climate change, because it leads to a reduction in the atmospheric carbon dioxide concentration. However, afforestation can be conducted for numerous purposes, and the complexity of tree species may render accurate estimation of the carbon (C) sequestration potential difficult. In this study, 22 cropland afforested plantations among 12 tree species and 4 study sites were investigated. We investigated stand development and aboveground biomass C accumulation of cropland afforestation in Taiwan, and examined how tree species and site conditions affected stand growth and yields. Results showed that average values of the mean diameter at breast height, tree height, stand density, and aboveground biomass C stocks for all studied plantation at 8-10 yr after planting were 12.1 cm, 8.5 m, 1272 trees ha-1, and 32.1 Mg C ha-1, respectively. The results also revealed that fast-growing tree species such as Swietenia macrophylla and Melia azedarach attained the highest growth rates and accumulated the most biomass C stocks, whereas slow-growing tree species such as Zelkova serrata exhibited the lowest growth rate and C accumulation potential. Trees grown at sites with deep soils outperformed those grown at sites with shallow and rocky soils. Overall, current cropland afforestation in Taiwan can enhance C sequestration, and also generate economic and ecological benefits. © 2016, Taiwan Forestry Research Institute. All rights reserved.

Аннотация: The Kulunda steppe is part of the greatest conversion areas of the world where 420,000 km2 grassland have been converted into cropland between 1954 and 1963. However, little is known about the recent and future impacts of land-use change (LUC) on soil organic carbon (OC) dynamics in Siberian steppe soils under various climatic conditions. By investigating grassland vs. cropland soils along a climatic gradient from forest to typical to dry steppe types of the Kulunda steppe, our study aimed to (i) quantify the change of OC stocks (0–60 cm) after LUC from grassland to cropland as function of climate, (ii) elucidate the concurrent effects on aggregate stability and different functional soil organic matter (OM) fractions (particulate vs. mineral-bound OM), and (iii) assess climate- and LUC-induced changes in the microbial community composition and the contribution of fungi to aggregate stability based on phospholipid fatty acid (PLFA) profiles. Soil OC stocks decreased from the forest steppe (grassland: 218 ± 17 Mg ha?1) over the typical steppe (153 ± 10 Mg ha?1) to the dry steppe (134 ± 11 Mg ha?1). Across all climatic regimes, LUC caused similar OC losses of 31% (95% confidence interval: 17–43%) in 0–25 cm depth and a concurrent decline in aggregate stability, which was not related to the amount of fungal PLFA. Density fractionation revealed that the largest part of soil OM (>90% of total OC) was associated with minerals and <10% of C existed in particulate OM. While LUC induced smaller relative losses of mineral-associated OC than particulate OC, the absolute decline in total OC stocks was largely due to losses of OM bound to minerals. This result together with the high 14C ages of mineral-bound OM in croplands (500–2900 yrs B.P.) suggests that mineral-bound OM comprises, in addition to stable OC, also management-susceptible labile OC. The steppe type had a larger impact on microbial communities than LUC, with a larger relative abundance of gram-positive bacteria and less fungi under dry conditions. Our results imply that future drier climate conditions in the Siberian steppes will (i) result in smaller OC stocks on a biome scale but (ii) not alter the effect of LUC on soil OC, and (iii) change the microbial community composition more than the conversion from grassland to cropland. © 2016 Elsevier B.V.

Аннотация: Changes in land use and climate are the main drivers of change in soil organic matter contents. We investigated the impact of the largest policy-induced land conversion to arable land, the Virgin Lands Campaign (VLC), from 1954 to 1963, of the massive cropland abandonment after 1990 and of climate change on soil organic carbon (SOC) stocks in steppes of Russia and Kazakhstan. We simulated carbon budgets from the pre-VLC period (1900) until 2100 using a dynamic vegetation model to assess the impacts of observed land-use change as well as future climate and land-use change scenarios. The simulations suggest for the entire VLC region (266 million hectares) that the historic cropland expansion resulted in emissions of 1.6? 1015 g (= 1.6 Pg) carbon between 1950 and 1965 compared to 0.6 Pg in a scenario without the expansion. From 1990 to 2100, climate change alone is projected to cause emissions of about 1.8 (± 1.1) Pg carbon. Hypothetical recultivation of the cropland that has been abandoned after the fall of the Soviet Union until 2050 may cause emissions of 3.5 (± 0.9) Pg carbon until 2100, whereas the abandonment of all cropland until 2050 would lead to sequestration of 1.8 (± 1.2) Pg carbon. For the climate scenarios based on SRES (Special Report on Emission Scenarios) emission pathways, SOC declined only moderately for constant land use but substantially with further cropland expansion. The variation of SOC in response to the climate scenarios was smaller than that in response to the land-use scenarios. This suggests that the effects of land-use change on SOC dynamics may become as relevant as those of future climate change in the Eurasian steppes. © 2021, The Author(s).
