“City-Scene” Characteristics and Optimization Strategies Research on Three Gorges Reservoir Area of the Post-Three Gorges Era

摘要

In the long-term symbiotic evolution process,the town areas along the Yangtze River and its natural and cultural landscapes have presented a sound 'city-scene' landscape form. But with the implementation of the Three Gorges project,the town relocation as well as the flooding in the natural and human landscape area,the original harmonious 'city-scene' pattern started to collapse and fell into the situation of 'fragmentation' and 'islanding'. The differentiation between city and landscape,uncoordinated scale and fractured urban context become pressing issues that affect the integral form optimization of the town areas. This paper aims at responding to the call of the government about proceeding the construction of the Yangtze River economic belt under the ecological and green strategy and seeking an attuned 'cityscene' relationship of the town area. Based on the analysis of the dynamic evolution of the 'city-scene' relationship,the paper also pointed out that the urban construction around the reservoir area in the postThree Gorges era was the key stage of 'scene-city' integration and symbiosis while the maintenance of scenery pattern,the harmony of space scale and the protection of living culture should be applied as the vital strategies.
