鄱阳湖典型湿地植物现状与保护策略

Current Status of and Conservation Strategy for Typical Wetland Plantsin Poyang Lake

鄱阳湖是我国最大的吞吐型、季节性浅水通江湖,呈现丰水期和枯水期周期性交替的独特水文节律。近年来鄱阳湖水位波动加剧,在各种因素及2020年特大洪水的影响下,鄱阳湖沉水植物呈退化趋势。综述了鄱阳湖湿地植物种类、典型湿地植物及其适应策略等,探讨鄱阳湖水文水质变化、10年禁渔、采砂等对沉水植物群落等分布的影响,为鄱阳湖湿地植物的保护及恢复提供参考。

Poyang Lake is the largest shallow,river connected lake in China,with significantly seasonal water-level fluctuation.It has the unique hydrological rhythm of dry season and wet season which alternates periodically.In recent years,the fluctuation of water level of Poyang Lake has increased,as a result of some factors and the catastrophic flood in 2020.Submerged plants in Poyang Lake showed a trend of degradation.This paper introduces number of wetland plant species in Poyang lake,typical species and adaptation strategies of which,discusses the impact of hydrology and water quality changes,ten-year fishing prohibition and sand mining on the submerged plant communities in Poyang lake,provides a basis for the conservation and restoration of the wetland plants in Poyang lake.
