三峡水库消落区生态环境现状及生物治理技术

The Status and Bioremediation Technology of Ecological Environment in Water-level-fluctuating Zone of the Three Gorges Reservoir

三峡水库消落区具有水淹时间长、消落幅度大、水位涨落节律逆反自然枯洪规律及面积大、生境类型复杂等特点。从三峡水库消落区目前所面临的生态环境问题出发,总结了国内外关于库区生态环境问题及生物治理的研究进展,提出了三峡水库消落区的生物治理方案。

Water-level-fluctuating zone of the Three Gorges Reservoir possesses some specific characters such as long flooding duration, wide-range fluctuation of water level （30 m）, reversed flooding time to winter, large area and complex habitat types and so on. Based on the ecological environmental problems of water-level-fluctuating zone of the Three Gorges Reser- voir, the ecological environmental problems and research advances on bioremediation technologies of water-level-fluctuating zone of the reservoir at home and abroad were summarized. The bioremediation strategies for water-level-fluctuating zone of the Three Gorges Reservoir were DrODosed.
