摘要
调查河段发现有鱼类48种,未发现国家级保护鱼类及云南省保护鱼类。糯扎渡电站建设会对鱼类资源产生不利影响,影响方式主要包括:库区淹没、大坝阻隔、下泄水物理化学性质改变、径流调节等。这些影响主要集中在电站运行期。通过对比分析,实施网捕过坝、建立鱼类增殖放流站和珍稀鱼类自然保护区,分层取水,实施结合资源、环境和渔政的保护管理等措施,可以将电站建设对鱼类资源的影响降到最低程度。同时,需要在糯扎渡电站影响范围内进行长期的跟踪调查和分析,实时针对性地提出保护措施。
There are 48 species of fishes in the investigation river. The national and provincial key protected species have not been found. The construction of Nuozhadu hydropower station would be harmful to fishes in this area.The main ways of influence covers reservoir inundation,dam block,Physical and chemical properties change of the drainage water,runoff regulation,and so on. These effects would mainly occur in the operating period of power station. The comparison and analysis,fishing with a net and moving the fishes to the downstream,selective withdrawal structures,the construction of fish restocking discharge station and natural conservation area,protection and management of the resources and environment can minimize the influences of power station construction on fish resources. At the same time,long-term tracking and analysis in the impact area of Nuozhadu hydropower station is needed,and putting forward the targeted protection measures timely is necessary too.
