“一条江”水电开发模式下的鱼类保护实践

Fish protection practices under condition of entire river hydropower development by a single company

雅砻江整江水电开发由雅砻江流域水电开发公司全权负责,因而可以做到在水电开发科学、有序、和谐的同时统筹规划采取环保措施,保护河流生态环境。针对雅砻江鱼类的分布特点、生活习性,雅砻江水电开发公司制定并实施了综合保护措施以将水电开发对鱼类资源的影响降低到最小,主要措施包括:建立鱼类自然保护区、大坝分层取水、生态流量下泄、鱼类栖息地修复、过鱼设施建设、鱼类增殖站建设等。鱼类保护设施建成运行后,为了检验鱼类保护效果,进行了实地调查分析。调查结果表明,鱼类保护设施的修建和运行取得了较好的效果。在总结鱼类保护设施建设、运行经验的基础上,提出了相关建议,以利于今后工作的改进。
