“…Since the lower canopy density results in higher soil temperature, which increases the decomposition rate of organic matter [17], the decomposition rate of organic matter may be higher before canopy closure. Contrary to Caragana, Hippophae, and Prunus plantations in the temperate Loess Plateau of China, where the SOC contents were higher in older plantations [19], in our study the C contents in the Chinese hickory stands remained similar, suggesting that the TOC contents could not be expected to increase under intensive management.…”

“…In Caragana korshinskii Kom., Hippophae rhamnoides L., and Prunus davidiana Carr. plantations, the SOC contents were higher in the 26-year-old than in the nine-year-old plantations [19]. Yet again, in Alberta, Canada, the differences in C stocks between native aspen forest and poplar plantations were mainly attributed to differences in plant biomass and not to differences in SOC content in the 0-50 cm soil layer [20].…”

To assess the effects of long-term intensive management on soil carbon cycle and microbial functional diversity, we sampled soil in Chinese hickory (Carya cathayensis Sarg.) stands managed intensively for 5, 10, 15, and 20 years, and in reference Chinese hickory–broad-leaved mixed forest (NMF) stands. We analyzed soil total organic carbon (TOC), microbial biomass carbon (MBC), and water-soluble organic carbon (WSOC) contents, applied 13C-nuclear magnetic resonance analysis for structural analysis, and determined microbial carbon source usage. TOC, MBC, and WSOC contents and the MBC to TOC ratios were lower in the intensively managed stands than in the NMF stands. The organic carbon pool in the stands managed intensively for twenty years was more stable, indicating that the easily degraded compounds had been decomposed. Diversity and evenness in carbon source usage by the microbial communities were lower in the stands managed intensively for 15 and 20 years. Based on carbon source usage, the longer the management time, the less similar the samples from the monospecific Chinese hickory stands were with the NMF samples, indicating that the microbial community compositions became more different with increased management time. The results call for changes in the management of the hickory stands to increase the soil carbon content and restore microbial diversity.

“…With the global implementation of forest landscape restoration to balance different functions at the landscape scale including water regulation, wildlife habitats, biodiversity and carbon storage (CS) 8 , the CS capacity of forest stands based on type and age has been studied extensively 9,10 . However, studies more often focus on carbon storage in soil (SCS) than on CS at the ecosystem level.…”

At an ecosystem level, stand age has a significant influence on carbon storage (CS). Dragon spruce ( Picea asperata Mast.) situated along the upper reaches of the Bailongjiang River in northwest China were categorized into three age classes (29–32 years, Y 1 ; 34–39 years, Y 2 ; 40–46 years, Y 3 ), and age-related differences in total carbon storage (TCS) of the forest ecosystem were investigated for the first time. Results showed that TCS for the Y 1 , Y 2 , and the Y 3 age groups were 323.64, 240.66 and 174.60 Mg ha −1 , respectively. The average TCS of the three age groups was 255.65 Mg C ha −1 , with above-ground biomass, below-ground biomass, litter, and soil in the top 0.6 m contributing 15.0%, 3.7%, 12.1%, and 69.2%, respectively. CS in soil and TCS of the Y 1 age group both significantly exceeded those of the Y 3 age group ( P < 0.05). Contrary to other recent findings, the present study supports the hypothesis that TCS is likely to decrease as stand age increases. This indicates that natural resource managers should rejuvenate forests by routinely thinning older stands, thereby not only achieving vegetation restoration, but also allowing these stands to create a long-term carbon sink for this important eco-region.

“…Generally, tree C stock increases as the stand age increases in Chinese fir (Lan et al 2016), Larix olgensis A. Henry plantations (Ma et al 2014), and Prunus davidiana (Carr.) Franch, Caragana korshinskii Kom., and Hippophae rhamnoides plantations (Dang et al 2017). Nevertheless, many tree C stock estimates have been obtained using a constant factor for the conversion of biomass to C stock, ignoring tissue-specific C stock.…”

& Key message Carbon (C) concentrations in Cunninghamia lanceolata (Lamb.) Hook plantations differed significantly among tissue types and were greater for aboveground than belowground tissues. Plantation C stock increased with a developmental stage from young to mature to overmature, but at all stages, the majority occurred as soil organic carbon (SOC) and was more influenced by belowground fine roots than by aboveground litterfall. & Context Failing to account for tissue-specific variation in the C concentration can result in inaccurate forest C stock estimates. & Aims We aimed to quantify the relative magnitudes of C stock for Chinese fir plantations at different developmental stages. Specifically, we focused on assessing tissue-specific C concentrations and C dynamics return of above-and belowground litterfall. & Methods Carbon traits (C concentration, C flux, C stock, and distribution at tree and ecosystem scales) were quantified in a chronosequence of Chinese fir (Cunninghamia lanceolata (Lamb.) Hook) monoculture plantation stands at young (10), mature (22), and overmature (34 years old) developmental stages. & Results Carbon concentrations differed significantly among tissue types, with mean values of 48.5 ± 0.1% and 42.5 ± 0.2% for above-and belowground biomass, respectively. The aboveground tissue C concentration, tree-and plantation-scale C stock, and SOC stock depended on developmental stage. Carbon return in litterfall, tree C stock, and SOC increased from the young to the overmature stage. SOC stock accounted for the majority of plantation C stock at all developmental stages (78.3, 59.6, and 55.7% in the young, mature, and overmature stages, respectively) and was more highly influenced by belowground fine roots than aboveground litterfall. Carbon stocks in Chinese fir plantations were 86, 129, and 153 t ha −2 at the young, mature, and overmature stages. & Conclusion Prolonging Chinese fir rotation increases C sequestration potential and should be the focus of forest management strategies. The tissue-specific C concentrations provide detailed information for more accurate biomass C stock estimates for Chinese fir plantations and other subtropical coniferous forests. They indicate that current guidelines result in an overestimation of belowground biomass C stocks. Using the standard 0.47 biomass to C conversion factor, the belowground C stock would have
