| 摘 要： | 葛洲坝的修建阻断了中华鲟的洄游路线,致使中华鲟的产卵场目前仅存葛洲坝下游不足7 km的河道内。针对十分脆弱的中华鲟产卵场环境,采用了有限体积法建立二维数学模型进行流场模拟计算,分析了中华鲟产卵对流场特性要求、不同流量条件下产卵场流场的特征以及隔流堤修建后对整个产卵场造成的不利影响,以期为今后产卵场的保护提供一定的理论依据。

| Abstract: | Since the migration channel of Chinese sturgeon is blocked due to theGezhouba project,it makes the length of spawning ground reduce to less than 7 km in the downstream of Gezhouba.Two-dimensional model is established to simulate the quite fragile environment of the Chinese Sturgeon spawning ground using the finite volume method.The flow field requirement of Chinese sturgeon spawning, characteristics of flow field under different discharge conditions,and negative effect of separation levee on the whole spawning ground are analyzed,which aims to provide reference for protection of the Chinese sturgeon spawning ground in future. |
