关 键 词：cascaded reservoirs eco-environmental impact operation 

摘      要：With the rapid development of cascaded reservoirs, a series of eco-environment problems have been produced, though the reservoirs have achieved great social and economic benefit in recent years. The impacts of cascade reservoirs operation on eco-environment have been generally analyzed, including the impacts on atmosphere, water, biology, river morphology, estuary, and reservoir geology. Some measures and methods are also put forward, such as perfecting rules and laws, consummating the control system and taking ecological operation. Through these measures, the eco-environment problems of river basin are believed to be solved to a certain extent.
