赣江作为鄱阳湖第一大河流,是鄱阳湖水系四大家鱼的主要栖息和繁殖场所。随着赣江上水利枢纽的逐渐增多以及其它环境胁迫的日益加剧,有必要了解水利枢纽兴建对以四大家鱼繁殖的影响。本文在阐述赣江梯级枢纽开发现状的基础上,分析了拟建新干枢纽对库区四大家鱼水产种质资源保护区的影响,并提出相应的保护建议。为进一步研究赣江流域四大家鱼产卵场奠定基础,并为赣江流域枢纽开发与鱼类资源保护的和谐发展提供参考。
As the largest river in Poyang Lake, Ganjiang River is the main habitat and breeding place of the four major fish in Poyang Lake water system. With the increasing number of water conservancy hubs in Ganjiang River and the increasing intensification of other environmental threats, it is necessary to understand the impact of the construction of a water control project on the reproduction of the four major domestic fish. Based on the status quo of the development of the cascade hub in Ganjiang River, this paper analyzes the impact of the planned hub of Xinjian Hydropower Station on the conservation areas of the four major marine fish aquatic germplasm resources in the reservoir area and puts forward corresponding protection suggestions. This will lay the foundation for further research on the spawning grounds of the four major domestic fish in the Ganjiang River basin and provide a reference for the harmonious development of the pivotal development of the Ganjiang River Basin and the conservation of fish resources.
