摘要: 建立中华鲟产卵场三维水流数学模型,模拟葛洲坝电厂不同调度情况下产卵场水流条件;分析了葛洲坝下游近坝段适宜中华鲟产卵的水深、近底层流速和两者叠加的区域范围;研究了葛洲坝电厂调度对中华鲟产卵场水流条件影响,并初步提出了中华鲟产卵场水流条件改善措施。研究结果表明:葛洲坝下泄流量在15000~6000m3/s范围变化时,适宜中华鲟产卵的水流区域范围随下泄流量减小相应减小;在下泄流量为6000m3/s情况下,若下泄流量全由大江电厂泄流时有利于增大大江尾水区适宜产卵的水流区域范围。

Abstract: A three-dimensional mathematical model of the flow at Chinese sturgeon spawning ground was established. The flow condition in the presence of different dispatching operation modes of Gezhouba power station was simulated by this model. The regional scale of water depth, bottom velocity and the superposition of the two of the area suitable for Chinese sturgeon spawning in the downstream near the Gezhouba Project was analyzed. The influence of Gezhouba Project dispatching on the flow condition of Chinese sturgeon spawning ground was studied, and measures of improving the flow condition of Chinese sturgeon spawning ground were discussed. The results show that when the discharge of Gezhouba Project varies in the range of 15 000-6 000 m3/s, the flow area suitable for Chinese sturgeon spawning decreases accordingly with the reducing of discharge; when the discharge is 6 000 m3/s, if all the flow is discharged by Dajiang Powerplant, it will be beneficial to increase the suitable flow area for Chinese sturgeon spawning.
