| 通过对2010年、2013年、2014年、2021年和2022年鄱阳湖大湖池和修河的日水位实测数据进行分析，研究大湖池与修河的河湖关系。结果表明：修河吴城站水位高于1636m呈现“高水似湖”，低于1636m呈现“低水似碟及低水似河”；水位为1036m～1636m时，大湖池的水位变化由闸口人为控制，大湖池与修河隔离（2013年、2014年）或连通（2010年、2021年、2022年）取决于修河水位与闸口控制水位的高低；大湖池与修河年内月平均水位值均表现为1月—7月逐月升高，8月—12月逐月降低，大湖池最低水位为湖底高程即大湖池干涸，修河最低水位每年不同且持续降低。 |
| 英文摘要: |
| This paper studied the relationship between Dahu lake and Xiu River in Poyang Lake by analyzing daily water level in 2010， 2013， 2014， 2021 and 2022. The results showed that when the water level at Wucheng Station in Xiu River was higher than 16.36 m， it was lake like， when the water level was lower than 16.36 m， it was saucer like or river like. When the water level was between 10.36 m and 16.36 m， the water level of Dahu lake was artificially controlled by the gate. The connection（in 2010， 2021 and 2022） and disconnection（in 2013 and 2014） between Dahu lake and Xiu River depended on the water level of Xiu River and the control water level at the gate. The monthly average water level of both Dahu lake and Xiu River increased month by month from January to July and decreased month by month from August to December. The lowest water level of Dahu lake was the elevation of the lake bottom， that is， the lake dried up. The lowest water level of Xiu River varied from year to year and 〖GK!86mm〗continued to decrease. |
