Abstract

The expansion of large-scale ports necessitates a delicate balance between operational efficiency and environmental preservation. Our study tackles this issue by exploring sustainable water exchange optimization in intricate port systems. Focusing on Dalian Port’s Taiping Bay as our research site, we integrate ecological principles into port development and apply a tidal flow model to assess the effects of diverse channel designs on water dynamics. A key advancement of our work is the refinement of the “retention factor” concept and the adaptation of the concentration-water exchange rate equation. This innovative approach allows for a more precise evaluation of water exchange capabilities amidst complex environmental scenarios. Our findings reveal that channel width plays a pivotal role in water exchange efficiency, with a notable plateau effect beyond a threshold that achieves a 90% exchange rate. These insights underscore the potential for design optimization that aligns with ecological sustainability, offering a roadmap for future port developments that prioritize minimal ecological disruption.

港口设计中加强水交换和环境可持续性：以大连港太平湾为例

大型港口的扩张需要在运营效率和环境保护之间取得微妙的平衡。我们的研究通过探索复杂港口系统中可持续的水交换优化来解决这个问题。本文以大连港太平湾为研究基地，将生态原则融入港口发展，并应用潮流模型评估不同渠道设计对水动力的影响。我们工作的一个关键进展是“保留因子”概念的细化和浓度-水交换率方程的适应。这种创新的方法可以更精确地评估复杂环境下的水交换能力。我们的研究结果表明，渠道宽度在水交换效率中起着关键作用，在达到90%的交换率阈值之后，存在显著的平台效应。这些见解强调了与生态可持续性相一致的设计优化的潜力，为未来港口的发展提供了优先考虑最小生态破坏的路线图。
