“…These observations correspond to those of a previous study that found that the elevational variations in bacterial community composition in different soil layers were significantly different (Tian et al, 2021). However, recent studies conducted in the Central Austrian Alps and northern Greater Khingan Mountains found that elevation had a stronger effect on soil microbial communities than soil depth (Bhople et al, 2022; Ji et al, 2022). These diverse results could indicate that soil bacterial and fungal community compositions respond differently to climate and edaphic properties along an elevational gradient, and that the elevational patterns of taxonomic groups in microbial communities are determined by distinct environmental factors (Ji et al, 2022; Shen et al, 2020).…”

Knowledge about the elevational patterns of soil microbial biomass and communities can facilitate accurate prediction of the responses of soil biogeochemical processes to climate change. However, previous studies that have considered intra‐ and inter‐annual variations have reported inconsistent results on the one hand, and they have paid little attention to the effect of soil layer on the other hand. We, therefore, conducted a 4‐year in situ soil core incubation experiment along a 2431‐m elevational gradient across the dry valley shrubland, valley‐montane ecotone forest, subalpine coniferous forest, alpine coniferous forest, and alpine meadow in an ecologically fragile alpine‐gorge region on the eastern edge of the Qinghai‐Tibetan Plateau. Soil microbial biomass and community composition in the organic and mineral layers were measured using the phospholipid fatty acids (PLFA) method at five critical periods each year. Our results indicated that soil microbial biomass in the organic layer was the highest in the subalpine coniferous forest, followed by the alpine meadow, alpine coniferous forest, and valley‐montane ecotone forest. In contrast, soil microbial biomass in the mineral layer was significantly higher in the alpine meadow than in the other sites. Soil microbial biomass exhibited differential seasonal fluctuations at different elevations, resulting in their elevational patterns being strongly intra‐annual and inter‐annual dependent. Our results revealed that elevation and seasonality significantly affected soil microbial communities. Seasonality had a more substantial effect than elevation on soil microbial communities during the first three years of incubation, whereas the relative importance of seasonal and elevational effects on microbial communities was reversed in the organic layer with incubation time. These results are mainly attributed to the magnitude and direction of effect of environmental variables on soil microbial biomass and communities vary with elevation, soil layer, and sampling time. Briefly, the elevational patterns and dominant factors of soil microbial biomass and communities have intense soil layer and temporal specificity, implying that differential responses of soil biochemical processes to climate change might be observed at different elevations.This article is protected by copyright.

“…In this study, native forests and eco‐forests with high SOC content were located at higher altitudes (>2200 m), while orchards with low SOC content were at lower altitudes (<2200 m) closer to the settlements (Figure 1). (2) Altitude‐dependent changes in SWC were another critical explanation for this phenomenon (Bhople et al, 2022; Guan et al, 2019; Tsozué et al, 2019). For higher altitudes with a higher SWC (Figure 3b), abundant vegetation, litter, and a slower SOC decomposition rate contributed to SOC accumulation (Choudhury et al, 2016).…”

“…Altitude gradients are often able to redistribute hydrothermal conditions at the regional scale. Hydrothermal differences can affect SOC distribution (Bojko & Kabala, 2016) by altering soil properties such as physics (Guan et al, 2019; Li et al, 2017), chemistry (Tsozué et al, 2019), soil microorganisms (Bhople et al, 2022; Yang et al, 2020), and vegetation distribution (Simon et al, 2018) and litter abundance (Hu et al, 2021). Various regions produce different results.…”

Few studies have been conducted on the factors and distribution of soil organic carbon (SOC) in plantation forests in arid mountainous regions, especially in orchards. We aimed to unravel the SOC distribution among land‐use types and the effects of altitude gradients and rock fragment content (RFC) on SOC accumulation and sequestration in the Upper Min River Arid Valley, China. The differences in SOC distribution among land‐use types were quantified. The correlation analysis of SOC with various factors, such as altitude and RFC, was conducted. The variation percentage in SOC content and stocks was explained by the factors' contribution using mixed‐effects models. SOC distribution was characterized by high content and low stocks in native forests and shrubs, high content and high stocks in eco‐forest, and low content and high stocks in orchards. At the surface (0–30 cm), SOC content and stocks in orchards (cherry, plum, and apple) were significantly lower than those in eco‐forests. There was a significant positive correlation between altitude and SOC content at the surface but not at the subsoil (30–60 cm). With RFC increased, the surface SOC content decreased in native forests, shrubs, and eco‐forests, while it increased in orchards. Our results suggest that land management is the main factor controlling the variation in SOC distribution. Enhancing the surface SOC stability in orchards by land management is a priority for soil carbon pool management in the Arid Valleys.
