Ecological Restoration for Littoral Zone of Reservoir

Water level regulation due to hydropower production has caused notable changes in the littoral zones of regulated lakes and rivers. Heavy geomorphologic, littoral benthos and vegetation changes have taken place in reservoirs with a fluctuation of water level. This paper presents an analysis of ecological and environmental problems in littoral zone of reservoir, including physical and geochemical problems, and problems for vegetation and animal. In accordance with these problems, four basic ecological restoration principles were put forward: integrated ecology, long term and stages, systematization, and multi-objects. Finally, four main kinds of ecological restoration model were introduced according to restoration principles. This paper could provide scientific principle and basis for maintaining ecological functions and protecting ecosystems in whole reservoir, keeping balance, safe and health of ecosystem in littoral zone of reservoir.
