三峡库区消落带分区固土护岸模式

Patterns of Soil Conservation and Revetment by District at Water-Level-Fluctuating Zone in Three Gorges Reservoir

三峡库区消落带是库区陆域与水库之间生态过渡的缓冲带,在生态系统中发挥着极重要的作用,也是生态系统极度脆弱的地区之一。保护三峡水库,使三峡工程有效运转,是该地区生态环境保护的当务之急。本文以消落带为研究对象,依据消落带功能及生态环境特点,论述了植被恢复与重建对消落带固土护岸的重要性,总结了固土护岸的植被技术及其与小型工程措施相结合的治理方法,并因地制宜地提出了消落带分区固土护岸模式,以期促进该模式的推广和应用,从而为长江三峡库区消落带的生态恢复与重建提供经验及技术支撑。

As the riparian buffer of ecotone between land and reservoir,the water-level-fluctuating zone in the Three Gorges Reservoir not only plays a significantly important role in the ecosystem,but also is the serious fragile zone of the ecosystem. It is imperative to protect local ecological environment through preserving the Three Gorges Reservoir and further ensuring the effective operation of the Three Gorges Project.According to the characteristics and functions of the water-level-fluctua-ting zone,and taking water-level-fluctuating zone as research object,the necessity of restoration and reestablishment of the vegetation to soil conservation and revetment,and further the methods of combining corresponding plantation technique and small engineering measures are studied.Finally,the patterns of soil conservation and revetment adjusted to local conditions are put forward.Concluded above,it is hoped that the ecosystem will be restorated and reconstruced in the water-level-fluc-tuating zone of Three Gorges Reservoir Area by applying soil and revetment technique.
