大型浅水湖泊鄱阳湖湿地微生物的研究现状

Research status of microorganisms in a large, shallow lake Poyang Lake wetland

摘要:

鄱阳湖是我国第一大淡水湖泊，同时也是一个典型的季节性通江浅水湖泊，独特的水文特征和多样的湿地景观类型形成了复杂多样的微生物群落。本文综述了鄱阳湖水文节律、营养盐及重金属含量对湖泊微生物群落组成的影响，以及水位高程和湿地围垦对鄱阳湖湿地土壤微生物分布特征的影响，同时还探讨了未来湖泊湿地微生物的研究方向和鄱阳湖所拥有的独特研究条件，以期为未来湖泊微生物研究提供重要参考。

Abstract:

Poyang Lake, the largest freshwater lake in China, is a typical seasonal shallow lake. Its unique hydrological characteristics and various wetland landscape types make the microbial communities complex and diverse. This paper summarized the current research status of the microbes in Poyang Lake on: (1) effects of hydrological rhythm, nutrients and heavy metal contents on the composition of microbial community in Poyang Lake; (2) effects of water level elevation and wetland reclamation on soil microbial distribution in Poyang Lake wetland. Meanwhile, the future research direction of microorganism in lake wetland and the unique conditions of Poyang Lake are also discussed, providing an important reference for studying lake microorganisms in the future.
