Abstract ：
Chinese fir forests play an indispensable role in both ecological and economic contexts, serving dual purposes in soil and water conservation, as well as providing significant economic benefits as an efficient timber-producing species. However, the issue of soil degradation due to continuous Chinese fir planting cannot be overlooked. Continuous planting leads to a decrease in soil nutrients, a reduction in microbial diversity, and changes in microbial community composition, which in turn affect the abundance of carbon and nitrogen cycle functional genes in Chinese fir forest soils. We utilized metagenomic sequencing technology to investigate the dynamics of microbial community composition and carbon and nitrogen-related functional genes in the soils of Chinese fir forests across different plantation generations, exploring their relationship with soil carbon and nitrogen nutrients. We found that bacterial communities at the phylum and genus levels dominate. The PLS-PM model indicates that planting generations have a negative effect on dissolved organic carbon (DOC), NO3--N, and microbial biomass nitrogen (MBN), with a significant negative impact on microbial residual carbon (MRC). Easily utilizable carbon nutrient (DOC) in Chinese fir forest soil shows a significant positive effect on the abundance of carbon fixation functional genes (direct effect = 0.91, p 3--N, MBN) in the soil also have a significant positive effect on the abundance of carbon fixation functional genes (direct effect = 0.90, p © 2024, The Authors.

为探讨红壤侵蚀区不同植被类型下土壤磷素有效性，选取福建长汀红壤丘陵生态系统国家定位观测研究站的裸地(CK)、针叶林(CF)、针阔混交林(CB)以及阔叶林(BF)4种植被类型，分别测定其铁氧化物、各级磷素形态，并采用高通量测序技术对解磷菌(PSM)进行测定。结果表明：随着植被类型的转变，中等活性磷含量增加，低活性磷含量总体上减少，游离态氧化铁(Fe_d)含量逐渐减少。土壤中解磷菌的丰富度和多样性随植被类型的转变增加。在门分类水平上，优势类群主要有变形菌门(Proteobacteria)、放线菌门(Actinobacteria)、异常球菌—栖热菌门(Deinococcus-Thermus)等。变形菌门和酸性磷酸酶的含量随植被类型的转变总体呈现出增加趋势，变形菌门与ACP呈极显著正相关。综上所述，随着植被类型转变，稳定态磷逐渐向可利用态磷转化，土壤潜在磷源增加；游离态氧化铁含量的减少有利于有机磷的解吸和矿化，进而增加磷的有效性；解磷菌群落结构与多样性变化会受到土壤理化性质的影响，解磷微生物可通过分泌酸性磷酸酶的方式水解有机化合物并降解固定在土壤的无机磷，进而提高磷的有效性。

Abstract ：
Studying the changes and linkages between dissolved organic matter (DOM) and microorganisms in soils during vegetation restoration will help to understand the role of vegetation restoration in soil carbon sequestration and thus improve the understanding of the global soil carbon cycle. Soil DOM molecules were characterized by Fourier-transform ion cyclotron resonance mass spectrometry (FT-ICR MS) and the results showed that the soil DOM consisted mainly of lignin/carboxylic rich alicyclic molecule (CRAM)-like structures, while the ratios of lipids and aliphatic/protein decreased in sequence with recovery time. Lipids and aliphatic/proteins with high H/C DOM (labile DOM) degrade preferentially, while lignin/CRAM-like structures and tannins with low H/C DOM (recalcitrant DOM) are recalcitrant during vegetation restoration. With the restoration of vegetation, DOM molecules tend to be diversified and complicated, and DOM compounds with low double bond equivalent (DBE), low aromatic, and low alkyl structures will be converted into persistent organic matter with high carbon numbers and high DBE. The diversity of soil microorganisms was determined by high-throughput sequencing. The results showed that the abundance and diversity of soil bacteria increased significantly after revegetation, while the abundance and diversity of soil fungi began to increase when the ecosystem became a more mature coniferous forest. The soil microbial community exhibited complex connectivity and strong interaction with DOM molecules during vegetation restoration. As most of the DOM molecules are recalcitrant, vegetation restoration facilitates C sequestration in the soil, thereby contributing to climate change mitigation.

Abstract ：
To identify possible dominating processes involved in soil microbial community assembly, dissolved organic matter (DOM) and multi-nutrient cycling (MNC) interactions and contribute to understanding of climate change effects on these important cycles, we investigated the interaction of soil chemistry, DOM components and microbial communities in five vegetation zones ranging from evergreen broad-leaved forest to alpine meadow along an elevation gradient of 290-1960 m in the Wuyi Mountains, Fujian Province, China. Soil DOM composition and microbial community assembly were characterized using Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) and Illumina MiSeq high-throughput sequencing, respectively. Sloan's neutral model and the modified stochasticity ratio were used to infer community assembly processes. Key microbial drivers of the soil MNC index were identified from partial least squares path models. Our results showed that soil DOM composition is closely related to the vegetation types along an elevation gradient, the structure and composition of the microbial community, and soil nutrient status. Overall, values of the double bond equivalent (DBE), modified aromaticity index (AI(mod)) increased, and H/C ratio and molecular lability boundary (MLBL) percentage decreased with elevation. Lignins/CRAM-like structures compounds dominated soil DOM in each vegetation type and its relative abundance decreased with elevation. Aliphatic/protein and lipids components also decreased, but the relative abundance of aromatic structures and tannin increased with elevation. The alpha diversity index of soil bacteria gradually decreased with elevation, with deterministic processes dominating the microbial community assembly in the highest elevation zone. Bacterial communities were conducive to the decomposition of labile degradable DOM compounds (H/C = 1.5) at low elevation. In the cooler and wetter conditions at higher-elevation sites the relative abundance of potentially resistant soil DOM components (H/C < 1.5) gradually increased. Microbial community diversity and composition were important predictors of potential soil nutrient cycling. Although higher elevation sites have higher nutrient cycling potential, soil DOM was assessed to be a more stable carbon store, with apparent lower lability and bioavailability than at lower elevation sites. Overall, this study increases understanding of the potential linkage between soil microbial community, multiple nutrient cycling and DOM fate in subtropical mountain ecosystems that can help predict the effect of climate change on soil carbon sequestration and thus inform ecosystem management.

Abstract ：
Characterization of soil dissolved organic matter (DOM) and understanding of the interactions between soil microbial communities and DOM molecules along elevation gradients in alpine ecosystems are still limited. To unravel these interactions and how they change along alpine elevation gradients, we sampled topsoil in the Sygera Mountains (Tibet, China) at elevations between 3800 and 4600 m. The molecular characteristics of soil DOM were determined using Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) and soil microbial composition was identified by high-throughput sequencing. Among the seven components of DOM, the lignins/CRAM (carboxyl-rich alicyclic molecules)-like structure dominated at all elevations, followed by tannins, while the relative abundance of unstable substances, including lipids, aliphatic/protein, and carbohydrates, was lower. As elevation increased, the molecular diversity, degree of oxidation, aromaticity, and unsaturation of soil DOM decreased. The abundance and diversity of soil bacteria and fungi also generally decreased with elevation. Both bacteria and fungi play an important role in the degradation of DOM molecules, but bacteria appear to have greater degradation ability. Among them, Proteobacteria and Bacteroidetes mainly promote the degradation of lignins/CRAM-like structure molecules, while Basidiomycota mainly degrade more unstable substrates. Co occurrence network analysis revealed complex correlations between specific microbial groups and DOM molecules. Our results suggest that more active cycling of soil DOM could occur in alpine ecosystems due to climate warming, as the result of increased vegetation productivity and litter input in response to rising temperature promoting the relative abundance of microbial groups capable of degrading lignins/CRAM-like structures in soil DOM.(c) 2021 Published by Elsevier B.V.

Abstract ：
We used metagenomics to investigate the rhizosphere microbial community assembly and functions associated with different nutrient cycles in Chinese fir at different monoculture times and growth stages. Mantel test results indicated significant positive correlations between soil TP contents and bacterial communities. The concentrations of soil AP also exhibited a significantly positive association with the fungal community. The relative abundance of ko00720 and ko00680 increased from young-old stands to mature stands. It then decreased in over-mature plantations (45 years) and had a recovery in 102-year-old stands. The potential degradation pathway of cellulose had the highest abundance in 26-year-old stands than the other aged plantations. Potential N cycling processes were dominated by assimilatory nitrate reduction to ammonium and dissimilatory nitrate reduction to ammonium pathways. The variation-partitioning analysis revealed that three forms of N contents (NH4+-N, NO3--N, and DON) comprised 7%, whereas the other soil properties constituted 15.6% variation in the relative abundance of the genes involved in N cycling. Thus, metagenomics elucidates the evolution characteristics of rhizomicrobial composition and their functional changes at different developmental stages of Chinese fir plantations, providing a suitable reference for the potential utilization of carbon and nitrogen properties.
