| 摘 要： | 鄱阳湖洲滩植物面积在鄱阳湖占很大比例,在维持鄱阳湖生态系统稳定上发挥着重要作用。本次调查选择鄱阳湖有代表性的蚌湖作为研究对象,对秋季洲滩植物群丛结构、分布范围、生物量等进行了调查,通过与历史调查数据的对比,发现鄱阳湖洲滩植物在过去的45年中,特别是近15年生物量下降趋势明显;曾为鄱阳湖洲滩优势种的芦苇、南荻在洲滩的分布范围严重萎缩,且生物量下降明显。

| Abstract: | The area of beach vegetation in Poyang Lake accounts for a large proportion,and it plays an important role in maintaining the ecosystem stability in Poyang Lake.Bang Lake was chosen as the study area.The survey covered structure of flora,range of distribution,and biomass of plant.Comparing with historical data,the biomass decreased significantly in the past 45 years,especially in the recent 15 years.The distribution range of Phragmites communis and Triarrhena lutarioriparia which were the dominant species before have been declining seriously as well as its biomass. |
