国家级自然保护区是保护生态资源、构筑国家生态安全屏障的重要组成部分。铜鼓岭国家级自然保护区以其独特的热带岛屿生态系统和丰富的生物资源而闻名。本研究利用16 S rDNA基因高通量测序技术，对10、20和30 cm深度土壤中的细菌群落多样性和组成进行了表征和比较。我们发现，从20厘米的土壤具有最高的多样性，并可能作为一个“中间桥梁”的动态分布之间的10- 30厘米的土壤样品。多样性格局表明，不同深度土壤中的主要优势类群差异显著。此外，绿弯菌是TNR土壤中最具活力的类群，与另一个丰富但很少报道的类群Verrucomicrobia一起，极大地增强了TNR土壤的微生物多样性。总的来说，这项研究的结果强调了迫切需要更好地了解细菌群落的变化，以应对人类活动和气候变化。
National nature reserves are important for preserving ecological resources and constructing national ecological security barriers. Tongguling National Nature Reserve (TNNR) is known for its unique tropical island ecosystem and abundant biological resources. This study was conducted to characterize and compare its bacterial community diversity and composition in soils from 10, 20, and 30 cm in depth using high-throughput sequencing of 16S rDNA genes. We found that soils from 20 cm had the highest diversity and might serve as a “middle bridge” to the dynamic distribution between the 10- and 30-cm soil samples. The diversity pattern indicated that the main abundant groups varied distinctly and significantly among soils of different depths. Moreover, Chloroflexi was the most dynamic group in TNNR soils, together with another abundant but rarely reported group, Verrucomicrobia, which greatly enhanced the microbial diversity of TNNR soils. Overall, the results of this study emphasize the urgent need for greater understanding of bacterial community variations in response to human activities and climate change.
