The treatment of hydro-fluctuation belt is of great significance to improve the ecological environment in the Three Gorges Reservoir Area. The traditional treatment methods of hydro-fluctuation belt focus on its own process and solve the pollution problem from the eco-technological level. However, it is not suitable for the treatment of hydro- fluctuation belt which is located in the center of city. This essay proposes that the treatment of hydro-fluctuation should be managed with method of urban design, integrating it into the overall urban function, taking the relationship between the hydro-fluctuation belt and city development into full account. After the overall urban design, pollution problem of the hydro-fluctuation belt will be resolved radically, and the hydro-fluctuation belt will become the sustainable power for city development.%消落带的治理对三峡库区生态环境的改善有着重大意义。传统的消落带治理方法注重的是对消落带自身的处理，关注的是从生态技术的层面来解决污染问题，但该方法不适宜于地处城市中间的消落带。本文提出利用城市设计的方法来治理消落带，将消落带的治理融入到城市整体功能中，统筹考虑消落带与城市发展的关系。经过统筹设计后，消落带污染问题得到根治，消落带也将由城市发展的软肋转变为城市可持续发展的助力。
