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.

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 ：
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。

[目的 ]分析不同代数杉木林的土壤有效氮含量变化，探讨硝态氮与不同分类水平的氨氧化古菌（AOA）群落结构、多样性之间的联系，为人工林土壤氮素的有效性和杉木林土壤质量评估提供参考。[方法 ]在福建南平选取4个代数的杉木人工林，采用高通量测序技术对PCR扩增的amoA基因进行测定，运用Mantel＿r相关分析、随机森林模型和偏最小二乘路径模型等分析方法研究不同代数的土壤有效氮含量与氨氧化古菌群落丰度、多样性之间的关系。[结果 ]随杉木连栽代数增加，硝态氮（NO_3~--N）含量显著下降，铵态氮（NH_4~+-N）和微生物量氮（MBN）含量变化不明显。土壤酶活性、氨氧化古菌群落丰度与多样性总体呈降低趋势，土壤有效氮含量与氨氧化古菌群落以及酶活性之间联系密切，其中，氨氧化古菌丰度与多样性指数是影响硝态氮含量的最主要因素。[结论 ]随着连栽代数增加，氨氧化古菌群落的丰富度与多样性一定程度上降低，除第4代土壤脲酶和氨单加氧酶活性略有上升，土壤氮循环相关酶活性基本呈降低趋势，从而导致土壤硝态氮含量显著降低，限制了杉木连栽林土壤氮素的有效性。

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.

[目的 ]研究降雨丰沛，土壤水分长期饱和条件下生物炭对杉木人工林土壤铁还原的影响，分析土壤铁还原菌、解磷菌群落结构变化规律，最终明确生物炭对土壤铁还原的影响及与磷形态转化的关系。[方法 ]以杉木人工林红壤为供试土壤，收集林下杉木叶烧制成300℃和500℃生物炭，以0、1%、3%占比添加生物炭进行40 d的室内培养。测定土壤基本化学养分，采用修正后的Hedley方法测定土壤中不同磷素形态含量，利用高通量测序技术分析土壤解磷菌与铁还原菌群落结构。[结果 ]淹水处理后土壤活性磷含量增多，并且随生物炭添加量的增加而增加，其中水溶态有机磷和碳酸氢钠态无机磷占比较大；残渣态磷含量随生物炭添加量的增加而减少。淹水处理组的铁还原菌基因拷贝数高于非淹水处理组，且同一水分条件下随生物炭烧制温度的增加而增加，淹水处理组的亚铁离子含量远高于非淹水处理，且随生物炭添加量的增加而降低，淹水处理组的土壤化学性质例如pH、全碳、全磷含量高于非淹水处理组，且随生物炭添加量的增加而上升。在淹水处理中土壤解磷菌群落丰富度随烧制温度的升高而增加，并且解磷菌群落结构和多样性增强。[结论 ]厌氧条件促进Fe(Ⅲ)还原，生物炭的添加改变了土壤化学性质，影响土壤解磷菌群落结构和多样性、铁还原菌的生长微环境，在微生物与Fe(Ⅲ)还原的双重作用下，促进残渣态磷与氢氧化钠态磷向水溶态磷和碳酸氢钠态有机磷转化，增强了土壤磷素有效性。因此，在南方降雨充沛地区，杉木人工林施加生物炭能够改善土壤养分状况，为杉木生长提供足够磷素。

Abstract ：
以二代杉木林地土壤为供试土壤，进行室内培养试验来探讨P肥与生物炭配施对杉木林地土壤养分和微生物结构的影响，为施用生物炭和P肥对我国经营南方杉木人工林的可持续性提供合理的依据。试验设置4组处理，进行150 d室内生物培养试验后测定土壤基本养分状况，同时采用高通量测序技术分析土壤细菌、真菌的群落组成，并对土壤主要养分与微生物类群的相关性进行分析。结果表明，与单施P肥处理组(P)相比，在施加P肥的条件下，配施的生物炭在氧化前后均能促进土壤全C、全N、全P,速效K的含量增加，同时也降低了硝态氮和速效P的含量，其中与施生物炭处理组(WBCP)相比，氧化生物炭处理组(OBCP)对速效P和溶解性有机碳的含量有显著的抑制作用；与原土(CK)相比，P处理组中土壤细菌相对丰度以及群落结构差异较小，而其他处理中土壤的细菌相对丰度以及群落结构差异较大；WBCP和OBCP处理组对土壤真菌种类影响弱于P处理组，不同生物炭的添加培养分别降低子囊菌门的相对丰度，提高了毛霉亚门的相对丰度；土壤基本养分含量与门、属水平下主要微生物类群具有密切的相关性。因此在施用P肥的土壤中添加生物炭，能够有效改善杉木人工林土壤的主要养分状况，总体上促进土壤微生物物种数的增加，但生物炭氧化后其改善效果减弱，在对主要微生物类群相对丰度的调节上具有差异。
