中文摘要：

人工湿地是一种新型污水处理技术，微生物作为人工湿地的主要分解者，在人工湿地去除水中污染物的过程中发挥着重要作用，因其高效污水净化能力目前已得到广泛关注。本文从人工湿地中的微生物多样性、微生物污水净化机理、研究方法及根际微生物的研究等方面介绍了微生物在人工湿地污水处理中的研究进展。指出根际微生物在人工湿地中的的分布和作用特点，以及开展研究的重要意义。

英文摘要：

Constructed wetlands are a new type of technical methods for wastewater treat- ment. As important decomposers, microorganisms play a key role in contaminants removal from constructed wetlands. Owing to its high efficiency for wastewater treatment, the mi- crobial community within these wetlands has received great attention recently. The research development on microorganisms in constructed wetlands for wastewater treatment is intro- duced in this article, which discussed the multiplicity of microorganisms, the purification mechanism for wastewater treatment, research methods and study on rhizosphere microor- ganisms. It showed the distribution and function characteristics of rhizosphere microorgan- isms in constructed wetlands, as well as the value to study.
