| 摘要: |
| 根据蚌湖和鄱阳湖修水站的水位同步观测资料,结合湖区地形,分析蚌湖与鄱阳湖的水量交换关系,并利用三峡工程对鄱阳湖修水、星子、都昌站水位影响的预测结果,讨论三峡工程对蚌湖水情的影响。结果表明:(1)丰水期蚌湖水位与鄱阳湖水位以相同涨落率变化,呈现出高水位的一致性,三峡工程对鄱阳湖修水站丰水期的水位预测结果,可以用来表示丰水期三峡减泄流量对蚌湖水情的影响;(2)枯水期蚌湖与鄱阳湖之间,由天然堤几乎完全隔离而成为一个相对独立的湖泊,进出湖水量很小,水位相对稳定在13.80m左右,枯水期三峡增泄流量、一般年份不会超过蚌湖13.80m的天然堤漫堤水位,因此对蚌湖水情影响较弱,不会对越冬珍稀候鸟构成严重威胁;(3)蚌湖相对于鄱阳湖的水位变化,总体上无明显滞后效应,仅当水位在13.80~14.50m之间时,其水位涨落率小于鄱阳湖水位的涨落率,表现出滞后现象,但历时较短。 |

| Abstract: |
| According to observed data at Banghu and Xiushui hydrologic stations, this paper in combination with topography of the lake region analyzes water exchange between Banghu Lake and Poyang Lake.On the basis of the prediction results of impacts of the Three-Gorges Project on water level at Xiushui, Xingzi and Duchang hydrologic stations in Poyang Lake, the authors analyzes the impacts of the Three-Gorges Project on water regime of Banghu Lake in detail. |
