海河水利

帕孜水利工程对鱼类生活与繁殖的影响主要体现在阻断库区内鱼类的洄游通道，削弱不同水域鱼类种群之间的遗传交流，进而可能导致种群整体遗传多样性下降。随着近年来国家对生态环境保护要求的不断提高，在新建水利工程的同时，同步建设生态鱼道设施已成为保障鱼类顺利通行的重要措施。鱼道设施的型式可通过数值模拟等技术手段进行优化与确定，以更好地满足鱼类洄游需求，促进水生态系统的健康与可持续发展。鱼道在保护鱼类资源和维护生态环境方面具有重要意义，其不仅是一项工程措施，更体现了水利建设与自然生态和谐共生的理念。

The impact of the Pazi Hydraulic Project on fish life and reproduction is primarily manifested in the obstruction of migration channels within the reservoir area, which weakens genetic exchange among fish populations in different water bodies and may lead to a decline in overall genetic diversity. With the continuous improvement of national requirements for ecological environmental protection in recent years, the synchronous construction of ecological fishway facilities alongside new hydraulic projects has become a crucial measure to ensure the smooth passage of fish. The type of fishway facility can be optimized and determined through technical means such as numerical simulation to better satisfy fish migration needs and promote the healthy and sustainable development of the aquatic ecosystem. Fishways hold significant importance in protecting fish resources and maintaining the ecological environment; they constitute not only an engineering measure but also an embodiment of the philosophy of harmonious coexistence between hydraulic construction and natural ecology.
