水利水电技术（中英文）

分析了长江水系四大家鱼资源繁殖的水文和水动力适宜条件需求,围绕上游控制性水库优化调控过程开展了针对性数学模型研究,提出一种有利于改善四大家鱼产卵环境的水库生态调度过程。所建模型初步量化了面向四大家鱼繁殖需求的动态调度过程,利用上游水库的调蓄功能,采用"先蓄后泄"的调度方式形成人工涨水过程,在不明显影响发电量的前提下,有利于达到刺激四大家鱼进行产卵的目的。

The suitable hydrological and hydrodynamical conditions for the reproduction of the four major Chineses carps in the Yangtze River System are analyzed herein,and then a study on the pertinent mathematical model is made around the optimized regulation process of the upstream controlling reservoir; from which a reservoir eco-regulation process favorable to improve the spawning environment of the carps is proposed. The dynamic regulation process for the reproduction of the four major Chinese carps is preliminarily quantified by the model established herein,i. e. it is favorable to get the target of stimulating the spawning of the carps by the regulation and storage function of the upstream reservoir with the artificial water-rising process created by the operation mode of"storing first and then discharging"under the premise that not impacting the power generation obviously.
