摘　　要：鄱阳湖水域类型有碟形湖、围垦湖、河道等,这些水域具有独特水位变化规律,选取鄱阳湖碟形湖水域代表“沙湖”、围垦湖水域代表“珠湖”、河道水域代表“赣江吴城段”这3类水域,基于对2022年水位实测数据进行水位变化分析。结果表明:①碟形湖水位变化受河道水位影响,丰水期碟形湖与河道联通,枯水期则隔离;②围垦湖水位不受河道水位影响,且丰水期也不受鄱阳湖水位影响,水位由围垦湖降雨及闸口人为控制影响;③河道水域水位变化受上游来水影响且变幅较大。碟形湖、围垦湖和河道这3类水域的水位变化特征不同,应按水域分类开展鄱阳湖研究。There are different water areas of Poyang Lake,such as dish-shaped lake,reclaimed lake and riverway,which have their own unique water level variation rules.Three types of water areas were selected,namely Shahu Lake in dish-shaped lake,Pearl Lake in reclaimed lake,and Wucheng Section of Ganjiang River in riverway,and the water level changes of 2022 water level data were analyzed.The results showed that:①The water level changes of the dish-shaped lake was affected by the water level of the river,the dish-shaped lake was connected with the river in the flood periods,but not in the dry periods.②The water level changes of the reclaimed lake was not affected by the water level of the river,and the flood periods was also not affected by the water level of the Poyang Lake,and the water level was controlled manually by the gate of the reclaimed lake.③The water level changes of the river bodies were influenced by the upstream inflow and had the greatest amplitude.Therefore,the ecological environment research of the three types of habitats of Poyang Lake of dish-shaped lake,reclaimed lake and riverway,should be studied differently and accurate research on Poyang Lake needs to be carried out according to water body categories.
