The deep sea area is an important component of the marine ecosystem. It has high pressure, low temperature, no light, and oligotrophic characteristics. The extremely special habitat has given birth to unique microbial communities. It is necessary to investigate the structure and composition of the microbial community in the deep sea and its relationship with the environment in order to analyze the role of microorganisms in the geochemical cycle.

深海区是海洋生态系统的重要组分，具有高压、低温、无光、寡营养等特征，极端特殊的生境孕育了独特的微生物群落。探究深海区微生物群落的结构组成，及其与环境之间的相互关系，对于解析微生物在地球化学循环中的作用十分必要。
