“…Vegetation types significantly affected the tree C density, which was greater in the broad-leaved plantation than in coniferous plantations (Zhang et al, 2020). It is generally accepted that broadleaved trees have relatively large biomass C (Zhang et al, 2020;Osei et al, 2022). In this study, the C density of tree root in SSP was higher than that in MPP, which was related to the physiological habit of tree species (Hu et al, 2021).…”

“…The average tree C density of three plantations was 9.9 kg m −2 . This value is higher than the tree C density of Asian forests of 3.4-8.6 kg m −2 (FAO, 2010), but lower than the average tree C density of 12.6 kg m −2 for typical evergreen broad-leaved forests (Zhang et al, 2020) and of 12.4 kg m −2 for tropical forests (Chaudhury et al, 2022). In addition, the average C density of the tree root was 2.1 kg m −2 , accounting for 11.2% of the total tree C density, which was in sharp contrast with the results of natural spruce forests in northwest China, where the root C density accounted for 4.9% of the total biomass C (Yue et al, 2018).…”

“…The uneven C uptake capacity of tree species leads to a significant influence on plant C sequestration (Kang et al, 2006;Thomas and Martin, 2012). Moreover, soil C stocks vary in plantations due to different quantities and quality of organic matter contributed to the soil by plant species (Subashree et al, 2019;Zhang et al, 2020). Broad-leaved trees usually have higher organic matter inputs to the soil (Vesterdal et al, 2008), while coniferous trees have lower litter decomposition rates (Yang et al, 2004a,b).…”

Establishing plantation forests significantly increases the carbon (C) storage of terrestrial ecosystems. However, how vegetation types affect the ecosystem C sequestration capacity is not completely clear. Here, a slash pine plantation (SPP), a Schima superba plantation (SSP), and a Masson pine plantation (MPP), which have been planted for 30 years, were selected in subtropical China. The C storage and distribution patterns of plant, litter, and soil were investigated and calculated. The ecosystem C density was 17.7, 21.6, and 15.3 kg m–2 for SPP, SSP, and MPP, respectively. Ecosystem C stocks were mainly contributed by tree aboveground (39.9–46.0%) and soil C stocks (41.6–44.2%). The ecosystem C density of SSP was higher than that of SPP and MPP, and significant differences were found among three plantations for both aboveground and underground C densities. The aboveground and underground ecosystem C storage of SSP was 27.4 and 53.4% higher than that of MPP, respectively. Meanwhile, root C storage of MPP was lower than that of SPP and SSP, while soil C storage of MPP was lower than that of SSP. In the understory layer, SPP had the highest C density, followed by MPP, and there was a significant difference in C density among three plantations. However, no significant difference was found for the ecosystem C distribution among three plantations. Our results show that vegetation types significantly affect C storage but not C distribution in forest ecosystems and establishing the broad-leaved plantation has the highest ecosystem C storage in the subtropics. This study provides a theoretical basis for us to choose appropriate forest management measures.

Subtropical forests are rich in vegetation and have high photosynthetic capacity. China is an important area for the distribution of subtropical forests, evergreen broadleaf forests (EBFs) and evergreen needleleaf forests (ENFs) are two typical vegetation types in subtropical China. Forest carbon storage is an important indicator for measuring the basic characteristics of forest ecosystems and is of great significance for maintaining the global carbon balance. Drought can affect forest activity and may even lead to forest death and the stability characteristics of different forest ecosystems varied after drought events. Therefore, this study used meteorological data to simulate the standardized precipitation evapotranspiration index (SPEI) and the Biome-BGC model to simulate two types of forest carbon storage to quantify the resistance and resilience of EBF and ENF to drought in the subtropical region of China. The results show that: 1) from 1952 to 2019, the interannual drought in subtropical China showed an increasing trend, with five extreme droughts recorded, of which 2011 was the most severe one; 2) the simulated average carbon storage of the EBF and ENF during 1985-2019 were 130.58 t·hm-2 and 78.49 t·hm-2, respectively. The regions with higher carbon storage of EBF were mainly concentrated in central and southeastern subtropics, where those of ENF mainly distributed in the western subtropic; 3) The median of resistance of EBF was three times higher than that of ENF, indicating the EBF have stronger resistance to extreme drought than ENF. Moreover, the resilience of two typical forest to 2011 extreme drought and the continuous drought events during 2009 - 2011 were similar. The results provided a scientific basis for the response of subtropical forests to drought, and indicating that improve stand quality or expand the plantation of EBF may enhance the resistance to drought in subtropical China, which provided certain reference for forest protection and management under the increasing frequency of drought events in the future.
