The construction of water resources and hydropower projects has a profound impact on the ecosystem service functions of rivers. This paper explores how these projects change the water flow, water quality, and biodiversity, and thus affect the ecosystem services such as provisioning, regulating, cultural, and supporting services. Although water resources and hydropower projects provide important means for clean energy and water resources management in human society, they also bring about problems such as eutrophication of water bodies and obstruction of fish migration routes. Through the analysis of existing cases, this paper puts forward several strategies to mitigate the negative impacts, including ensuring ecological flow, constructing fishways, and environmental monitoring, etc. Reasonable planning and scientific management are the keys to achieving the harmonious coexistence of water resources and hydropower projects and river ecosystems.
