| 摘 要： | 根据三峡工程蓄水前后的实测资料，分析了荆江河段沿程水位流量关系变化。研究成果表明：除枝城站在枯水流量下水位略有下降外，上荆江在中、枯流量下水位也均有一定程度的下降，其中沙市站枯水位下降最大，下荆江河段水位在同流量下略有下降。除枝城站枯水位变化受卢家河浅滩形成的沙坎石泓影响外，三峡工程蓄水后影响荆江河段水位流量关系变化的...

| Abstract: | The change of stage-discharge relation along the Jingjiang river is analyzed based on the field data before and after the impoundment of Three Gorges Reservoir.Results show that the water level during low flowrate at Zhicheng station decreased slightly.Apart from that,the water level during medium and low flowrate decreased to some extent at stations in the upper Jingjiang reach,among which Shashi station witnessed the largest decline of low water level.The water level in lower Jingjiang reach also decrease... |
