使用生物指标来监测湿地的健康和功能一直是湿地科学家和管理者的一个持续目标，并且主要侧重于监测宏观生物的变化，因为它们相对容易识别和计数。近年来，高通量测序技术的建立、特定功能基因检测方法的开发以及更好的定量测量方法使得我们更容易获得各种微生物群落的广泛多样性概况和更可靠的丰度估计，并使我们能够探索湿地微生物组及其在生态系统功能中的作用。这种启发式搜索使我们能够关注微生物群落的少数群体，而这些群体很难通过更传统的分子工具进行仔细检查。监测微生物指标对养分负荷、污染物和氧化还原电位的响应有利于湿地生态系统管理。微生物种群可以作为响应各种环境变化最敏感、最快速的生物指示剂。单一的物理、化学或生物参数不能有效地满足湿地状况和恢复的评估，但多种属性的组合可以有效地进行稳健的湿地评估和管理。微生物的各种功能群可以作为湿地评估工具，提供对微生物种群动态和各种直接微生物活性测量的更深刻的理解。了解控制人工湿地生物地球化学循环的微生物群落可以支持优化这些有前途的处理系统的性能。本综述重点关注微生物作为湿地管理有效生物指标的潜在用途。
The use of biological indicators to monitor the health and functioning of wetlands has been an ongoing goal of wetland scientists and managers, and has focused primarily on monitoring the changes in macroorganisms, due to the relative ease of identifying and counting them. In recent years, the establishment of high-throughput sequencing techniques, development of assays for specific functional genes, and better quantitative measures are making it easier to get extensive diversity profiles and more robust abundance estimates of various microbial communities, and empowers us to explore wetland microbiomes and their role in ecosystem function. This heuristic search enables us to illuminate a spot light on minor populations of microbial communities, which were difficult to be scrutinized by more traditional molecular tools. Monitoring microbial indicators in response to nutrient loading, pollutants and redox potential is beneficial for wetland ecosystem management. Microbial populations can serve as the most sensitive and rapid bioindicator in response to various environmental changes. Evaluation of wetland condition and restoration cannot be met effectively by a single physical, chemical or biological parameter but a combination of multiple attributes is effective for robust wetland assessment and management. Various functional groups of microorganisms can be used as wetland assessment tools and provide a more profound understanding of microbial population dynamics and various direct microbial activity measurements. Understanding of the microbial communities controlling biogeochemical cycles in constructed wetlands could support optimizing performance of these promising treatment systems. This review focuses on a potential use of microorganisms as effective biological indicators for wetland management.
