Research on fish resources protection and ecological restoration in the construction of hydropower stations in plateau areas

The plateau regions are characterized by significant topographic relief, and the construction of hydropower stations has become an effective component of economic development. However, the construction of hydropower stations can lead to damage to fish resources and the aquatic ecological environment. This paper focuses on the protection of fish resources in hydropower stations in plateau regions and finds that dam construction and power plant construction can restrict the migration of fish and affect fish diversity. Water storage during the dry season can increase fish diversity in rivers, but the release of flow in the reduced water section not meeting standards can also have a certain impact on fish diversity. Therefore, this paper suggests that fish resource protection and ecological restoration can be carried out through engineering and non-engineering methods.
