摘　　要：三峡大坝的修建在取得航运、防洪、发电等社会经济效益的同时,也给库区消落带生态环境造成了不利影响。以生态学思想为指导的景观基塘系统、湖岸生态缓冲带、林泽系统和生境岛屿结构设计,有助于汉丰湖城市护岸水质净化、景观优化,及生物生境等综合生态服务功能的实现,并促进汉丰湖湿地景观建设与人居环境的协同共生。以重庆开县汉丰湖消落带为对象,研究了反季节水位变动背景下的湖城共生复合生态系统的恢复重建模式与方法。本研究是对城市消落带生态护岸结构设计思路与方法的全新探索,将为库区沿岸其他城市消落带相关研究和工程实践提供参考。The construction of Three Gorges Dam contributed significant social economic benefits on navigation, flood control and power generation while leaded some negative effects to the ecological environment. The landscape dike-pond system, lakeshore ecological buffer zones, littoral woodland and habitat islands which were designed based on the ecological principles are beneficial to the relazation of ecologcial services such as water purification, landscape optimization, and biology habitats, promoting a harmonious coexistence relationship between wetland landscape construction and inhabitation environment in Hanfeng Lake. Take the drawdown zone of Hanfeng Lake in Kai County, Chongqin as object, this paper studied the restoration mode and method of the land-city symbiotic eclogical system in the off-season water level fluctuation background. This study was a new exploration of ecological bank structure in drawdown zone of city, providing advisable experience and reference for the revetment construction for other cities along the Three Gorges Reservoir.
