三峡工程是当今世界最大的水利枢纽工程.三峡水库竣工运行后,库区将出现落差达30 m的消落带. 消落带是水陆生态交错带的一种类型,在流域生态系统中发挥着重要作用,具有较高的生态、社会和经济价值.其功能包括:缓冲带功能、保持生物多样性及保护生境的功能、护岸功能和经济美学价值等.从三峡水库消落带生态环境特征和生态功能出发,剖析了三峡水库消落带面临的主要生态环境问题,如生物多样性减少,污染加剧,库区土地资源锐减,环境地质灾害加剧,旅游资源恶化,流行性病情和疫情的发生,生态系统更为脆弱等.针对这些问题从系统全局的高度提出了三峡水库消落带环境保护和综合防治对策,为科学地制定三峡水...

The completion of the Three Gorges Dam will form 30-meter-high water level fluctuation zone （WLFZ）in the three gorges reservoir area . As a kind of aquatic-terrestrial ecotone,WLFZ plays an important role in the watershed ecosystem, and has high ecological, social and economic values. Its functions include WLFZ buffer, conservation of biological diversities and special habitats,dike protection from soil erosion,and economic and esthetics values and so on. This paper presented the main ecological and environmental challenges in the WLFZ includ...
