Due to human activities and the invasion of , the population of () in the Yangtze River Estuary has gradually declined. To address this issue, numerous restoration efforts have been undertaken. To investigate the changes and influencing factors of soil bacterial communities during the restoration of wetlands, we selected populations as the research focus and divided the samples into two years, S1 and S2. High-throughput sequencing technology was employed for observation and analysis. The results revealed that from S1 to S2, soil bacterial diversity in the wetland increased significantly and displayed clear seasonal patterns. The dominant bacterial phyla included Proteobacteria, Bacteroidota, Firmicutes, and Acidobacteriota. Among these, Proteobacteria had the highest relative abundance, while Acidobacteriota showed the most pronounced increase, surpassing Bacteroidota and Firmicutes to become the second most abundant group. Redundancy analysis (RDA) indicated that soil organic matter and electrical conductivity were the key factors influencing the composition and diversity of the soil bacterial community, with Acidobacteriota playing a dominant role during wetland restoration. In conclusion, during the ecological restoration of the wetlands, attention should be given to environmental factors such as soil organic matter and electrical conductivity, while the regulatory role of Acidobacteriota in wetland soils should not be overlooked. This study provides a microscopic perspective on the interactions between microbial diversity and ecosystem functions in coastal wetlands, offering valuable guidance for the ecological restoration of degraded wetlands.
由于人类活动以及[物种名称]的入侵，长江口[物种名称]的种群数量逐渐减少。为解决这一问题，已开展了多项修复工作。为调查[湿地名称]湿地修复过程中土壤细菌群落的变化及影响因素，我们选取[物种名称]种群作为研究重点，并将样本分为S1和S2两年。采用高通量测序技术进行观测与分析。结果表明，从S1到S2，[湿地名称]湿地的土壤细菌多样性显著增加，并呈现出明显的季节模式。优势细菌门类包括变形菌门、拟杆菌门、厚壁菌门和酸杆菌门。其中，变形菌门的相对丰度最高，而酸杆菌门的增加最为显著，超过拟杆菌门和厚壁菌门成为第二丰富的类群。冗余分析（RDA）表明，土壤有机质和电导率是影响土壤细菌群落组成和多样性的关键因素，酸杆菌门在湿地修复过程中起主导作用。总之，在[湿地名称]湿地的生态修复过程中，应关注土壤有机质和电导率等环境因素，同时不应忽视酸杆菌门在湿地土壤中的调节作用。本研究为沿海湿地微生物多样性与生态系统功能之间相互作用提供了微观视角，为退化湿地的生态修复提供了有价值的指导。
