“…In the old forest stand age, structural and functional complexity can affect the routing of precipitation through canopy interception, throughfall and stemflow in the forest ecosystem (Kermavnar & Vilhar, 2017). Moreover, the effect of stand age on litter amount may affect water flow in a Chinese fir plantation (Zeng et al, 2021). High litterfall could further intercept surface runoff and rainfall and ultimately maintain high storage of water with increasing stand age (Sangha et al, 2006).…”

“…Forest ecosystems provide multiple ecosystem services and functions (e.g., nutrient dynamics, carbon storage, climate regulation, water holding, wood production, biodiversity and litter decomposition) (Byrnes et al, 2014). The capacity of ecosystems to provide multiple services and functions (multifunctionality) has attracted strong interest from scientists, policy‐makers and land managers (Byrnes et al, 2014; Jonsson et al, 2020; Zeng et al, 2021). Ecosystem multifunctionality enables the synthesis of the multiple diverse ecosystem services and functions to avoid a biased perception of forest management practice (Delgado‐Baquerizo et al, 2020).…”

“…In recent years, the role of plantations as providers of ecosystem multifunctionality has become topical (Selvaraj et al, 2017; Yao et al, 2014; Zeng et al, 2021). However, a lot of studies addressing the effects of chronosequence on forest ecosystem multifunctionality have focused on secondary forest succession (Lucas‐Borja & Delgado‐Baquerizo, 2019; Jönsson et al, 2020; Shi et al, 2021).…”

“…Chinese fir plantation covers approximately 9 million ha in China, occupying 24% of the total plantation area in China (MacDicken., 2016). However, the rapid development of Chinese fir plantation has caused many concerns (Zeng et al, 2021), such as the severe degradation of soil quality and fertility (Ma et al, 2007) and biodiversity loss (Ares et al, 2010; Chen et al, 2021) under shortened rotations. Therefore, the rapid growth and intensive management practices of Chinese fir plantations in some regions have caused potential functional degradation, including soil nutrient deficiency, reduced litter decomposition and biological stability (Ares et al, 2010; Zeng et al, 2021).…”

Chinese fir (Cunninghamia lanceolata) is the main plantation species in the subtropical region of China. However, the shift in ecosystem multifunctionality with stand development remains largely unexplored for these plantations. This study used a chronosequence to investigate the variations of ecosystem multifunctionality by employing individual functions and identified its driving factors in Chinese fir plantations. The findings provide strong evidence that the individual functions of carbon stocks, water regulation and wood production increased with stand ages, but the tradeoff of individual functions did not significantly increase ecosystem multifunctionality. Soil microbial parameters (the abundances of bacteria, fungi and actinomycete), soil properties (soil moisture, total carbon and total nitrogen), and plant parameters (the shrub layer cover and total understory cover) exhibited positive correlations with ecosystem multifunctionality. The structural equation model revealed that plants, soil properties and microbes pathways explained 83% of the total variance in ecosystem multifunctionality. Results showed that plants, soil microbes and properties directly and significantly affected ecosystem multifunctionality with path coefficients of 0.404, 0.487 and 0.334, respectively. Soil microbes were identified as the top direct predictor for ecosystem multifunctionality, while plant and soil properties had strong direct and positive effects on ecosystem multifunctionality. These results verified that soil microbes, plants and soil properties directly and positively regulated ecosystem multifunctionality. Our findings demonstrate that ecosystem multifunctionality should be considered as a comprehensive ecological indicator for ecosystem services and functions, and sustainable plantation management. This study highlights the importance of conserving soil microbes for maintaining multifunctionality in Chinese fir plantations.

Stoichiometric characteristics of medium‐ and micro‐elements (Ca, Mg, Fe, and Mn) in soil aggregates as affected by stand age in Chinese fir plantations

et al. 2022

In order to understand the fertility of soil comprehensively in Chinese fir plantations, the stoichiometric characteristics of soil nutrient elements should be paid more attention to. Despite the broad investigation of the stoichiometry regarding soil C, N, P, and K, the stoichiometry regarding soil Ca, Mg, Fe, and Mn remains unclear.Therefore, this research aimed at exploring how the medium-and micro-element (Ca 2+ , Mg 2+ , Fe 2+ , and Mn 2+ ) contents, stocks, and their stoichiometric ratios (Ca 2+ / Mg 2+ and Fe 2+ /Mn 2+ ) in soil aggregates varied with Chinese fir-planting age (3, 9, 17, and 26 years) in the soil profile (0-40 cm). Our results showed that the stand age affected the stoichiometric characteristics of soil medium-and micro-elements in Chinese fir plantations, but such effects at the soil depth of 0-30 cm were more obvious compared with those at the 30-40 cm. At the soil depth of 0-30 cm, soil Fe 2+ and Mn 2+ were gradually accumulated over time, whereas soil Ca 2+ and Mg 2+ were susceptible to leaching and fir up taking. In the process of Chinese fir planting, decreasing soil Ca 2+ and Mg 2+ , especially the Ca 2+ (as demonstrated by decreasing soil Ca 2+ /Mg 2+ ratio), could cause soil acidification. And then, soil acidification could lead to more Fe 2+ and Mn 2+ released by accelerated mineral collapse, especially the Fe 2+ (as demonstrated by increasing soil Fe 2+ /Mn 2+ ratio). Overall, the present research advances knowledge of soil nutrient dynamics in Chinese fir plantations and provides supplementary information for the ecological stoichiometry of soil in the terrestrial ecosystem elsewhere in the world.

Exploring the variations of soil bacterial communities can contribute to the sustainability of Chinese fir plantations (CFPs). As the living environments of soil bacteria, soil aggregates significantly affect the diversity and composition regarding soil bacterial communities in CFPs. However, the distribution characteristics exhibited by soil bacteria at the aggregate scale are still not clear. In the present research, the diversity and composition regarding soil bacterial communities (using high-flux sequencing) in CFPs with diverse stand ages (3, 9, 17, and 26 years) were analyzed from the perspective of soil aggregates (>2, 1-2, 0.25-1, <0.25 mm) in Guangxi, China. According to the results, regardless of the aggregate size and the stand age, bacterial communities in soil were mainly composed of Proteobacteria, Chloroflexi, and Acidobacteria. During Chinese fir growth, the relative abundance (RA) of soil Proteobacteria first elevated and afterwards reduced, with the greatest level in the 17 years, while that of soil Chloroflexi exhibited an inverse trend. In addition, the RA of soil Acidobacteria increased over time. At the aggregate scale, the 17-year-old CFPs presented the greatest soil bacterial community diversity (based on the Chao 1 and Shannon indices). After 17 years, the destruction of coarse macroaggregates (>2 mm) could induce the reduction of soil bacterial community diversity, as coarse macroaggregates, taking up the majority of bulk soil, offered suitable environments for soil bacteria to survive and thrive. Moreover, soil organic C and total N concentrations and soil pH also significantly affected the diversity and composition regarding soil bacterial communities over time. Hence, the conservation of coarse macroaggregates after 17 years of Chinese fir growth is important to sustain the soil health as well as the bacterial community diversity in Guangxi, China.
