| 摘 要： | 目的]了解鄱阳湖区水体的质量状况。方法]于2014年对鄱阳湖区域的浮游藻类组成进行季节性调查。根据湖区浮游藻类的种类和数量,利用指示生物法和藻类多样性指数法(Margalef和Shannon-Weiner多样性指数)对其水质进行评价。结果]从鄱阳湖的样品中共鉴定出浮游藻类共5个门36个属62个种。鄱阳湖浮游藻类群落组成中,绿藻门和蓝藻门在种类和数量上均占据优势,其次为硅藻门。根据多样性指数和物种丰富度指数来看,鄱阳湖水体已经存在严重的污染问题。结论]调查结果为鄱阳湖的水体质量评价及后期的生态修复提供了理论依据。

| Abstract: | Objective] The aim was to understand the water quality condition of Poyang Lake.Method] The composition of phytoplankton in the lake was investigated in 2014.Based on the species and quantity of phytoplankton,biological assessment of water pollution and eutrophication con-dition were conducted by using the methods of indicator organism and biotic diversity index (Margalef and Shannon-Weiner index).Result] A total of 5 phyla,36 genera and 62 species of phytoplankton were identified from all samples.In the phytoplankton community,Chlorophyta and Cy-anophyta were dominant in both alga species and quantities,followed by Bacillariophyta.Both of the index about diversity and dominant were showed that this lake had been polluted seriously.Conclusion] The results provide theoretical basis for water quality evaluation and ecological restoration of Poyang Lake. |
